Working with a torque wrench can drastically reduce the chance of damaging any parts on yo🔥ur bike or having them come loose while riding. A torque wrench is a tool that allows you to tighten all the bolts and components on your bike to the manufacturer's recommended torque specifications. Modern bikes and components all have specific torque ratings, and adhering to them can prevent damage, especially on modern carbon fibre frames and parts. Owning one will help you work on your bike accurately and safely and even help you save money long term.
A torque wrench will allow you to quickly and safely tighten your bike's fasteners or bolts to the correct torque spec every time. This helps protect the delicate and lightweight components that are now so commonplace on the 澳洲幸运5开奖官网在线查询开奖结果:best road bikes, as well as prevent a failure or mechanical whilst ou✃t on a⛦ ride.

❌ You want to torque past 15Nm: Most bike components dont need high torque rates, b🦩ut if you do its worth noting this torq🅺ue wrech only goes to 15Nm.
The Pedros Demi Torque wrench gets our best overa⛄ll spot and brings 🌠a lot to the table if you're shopping for a torque wrench.
The wrench itself is a compact and lightweight unit that covers a torque range of 3-15Nm. This is similar to several wrenches in the guide and will have you covered for a lot🐎 of common maintenance tasks on the bike. You'll be able to torque all of your handler and stem bolts, most component bolts like derailleurs and brakes, not to mention a range of accessories and computer mounts.

✅ You need to work up to 60Nm: The high torque range is perfect for torquing💖 🌞things like cassette lockrings and cranksets.
Don't buy it if
❌ You need to torque bolts below 10Nm: Most handlebars stem bolts and seatpost clamps are only 𓄧torqued 🀅to 4 to 6Nm.
The BBB BTL-175 is the best option if you're looking for a big🧜ger torque wrench to torque things like cassette lockrings and chainset bolts, which often have higher torque ratings.
The unit covers a 10-60Nm range and uses a larger 1/2" drive, it's a solid feeling aᩚᩚᩚᩚᩚᩚᩚᩚᩚ𒀱ᩚᩚᩚnd is my go-to wrench to use at home for the aforementioned jobs like crankset bolts with higher torque ratings. It would also be great for shop mechanics for everyday use.
The adjuster dial on the end is easy to adjust, and I can adjust from the zero setting of 10Nm up to 40Nm for a cassette lock ring in 🏅just a few seconds.
The zippered foam-lined case is nice to work out of, and there'💧s a velcro pouch inside which contains the calibration certificate but you could also keep useful spares or small tools in here.
Not all of my tools and sockets are 1/2" so I purchased a convertor socket so I can use all of my tools❀ with the wrench. You may꧃ want to do the same if you're in the market.

Don't buy it if
❌ You are on a budget: This is a pꦯricier option compared to manual torque wrenches.
The Topeak D-Toꩲrq DX is an electronic, 3/8" drive torque wrench that 🍎covers a huge torque range of 4-80 Nm, meaning this torque wrench has the ability to cover everything on a bike.
If you 🥂like the idea o🍬f an electronic torque wrench and also like the idea of using one wrench for everything the D-Torque DX will allow you to hit the ground running.
It comes in a smart carry case with one of the largest ranges of included bits and sockets including a 1/2" inch drive converter socket, something I mention needing when using the BBB option. I also really like the carbon effect surround in the case𒀰, it just looks techy and cool.
Another point that highlight itself to me whenever I use the wrench is the ease with which you can set your desired torque with the soft rub🌠ber buttons compared to manually adjusting a mechanical wrench. If you suffer from any arthritis or similar issues and want to keep repetitive movements to a minimum this makes things really useful and saves some effort. I know I tried to minimise repetitive movements when spannering all day every day. The wrench then beeps not clicks when you reach your desired torq▨ue rating.
Though the wrench covers a huge range of torque it is a little longer than some of the more compact wrenches i🍷n the guide and may make working in tighter spots a little awkward, just something to think about, although you could always invest in a smaller or pre-set unit at a later date.

If you want to treat yourself or are perhaps buying the cyclist in your life a special present, you might want to look at the Effetto Mariposa Giustaforza 1-15 Pro Evo.
Effetto Mariposa overhauled its torque wrench lineup this year and the 1-15 Pro Evo superse𝄹des the Giustaforza 2-16 Pro model that was previously featured in our guide.
The new 1-15 Pro Evo gets an oil-slick finish which is rather flashy, though admittedly it doesn't bring any extra functionality to the table. It does make for a more special feeling though. The Pro Evo gets a 1-15Nm torque range, which has changed slightly from the old units 2-16 and also features a clockwise and counter-clock💝wise tightening calibration, useful for suspension hardware and the like.
Also new is the new micro-scale on the torque adjusting dial, which also locks into place, I've found this very useful on parts that have a specific torque reading like 6.2Nm for exꦐample.
The wrench is avai꧃lable on its own or with a nice tool roll and bits as pictures for some extra cash. There is also a standard 'Pro' model available for less cash which is all red, and just loses out on the dual-direction torque tightening feature the Evo gets. There are less expensive wrenches in this guide which offer similar performance points but if you're looking for a special feeling tool to use at home or ꧂work, the Guistaforza remains a nice, high-end option.

✅ You want a quality, well-constructed torque wrench: Comfꦰortable handle and durable finish make this a great option for working with all day.
✅ You want an accurate torque wrench: The Click Torque A5 is calibrated to the ne𒅌west, most stringent ISO standard.
Don't buy it if
❌ You need to work past 25Nm: Enough range for all but the hi🌃ghest torque needs.
❌ None of your sockets are for 1/4" drive: The 1/4" drive and the fact it doesn'💯t include bits means you may need to invest in extra bits or adapter🍎s.
The Wera Click Torque A5 is a 1/4" drive click-style torque wrench with an operating range of 2.5-25nm. This means it's suitable for everything on the bike, except cassette and disc lockrings and larger crankset bolts. It's 30 cm long making it mid-si𓆉zed against the wrenches in this guide. It's definitely a tool for home use rather than travelling or riding with.
It's a larger unit ꩵand will be highly accurate and reliable, making it ideal for shop environments. The A5 conforms with the ISO678-1:2017 calibration standard and comes with a certifi🍨cate of conformance. I learnt during my metrology lab visit that the 2017 standard is very stringent and checks the torque wrench across a great many test points.
It uses a 1/4" square drive fitting and doesn't co💃me with🦩 bits. So you may need to invest in some 1/4" drive bits and adaptors as needed.
I liked the ergonomic, comfy handle, and if you were using𝓡 this wrench several times a day I think it would start to come into its own. The click when torque is reached is also loud and easily audible. Once the bottom adjuster dial is pulled open the whole lower body of the torque wrench rotat🧜es with a really nice light action allowing you to set the desired torque spec quickly and easily.
This isn't specifically a shꦬop-level tool💫 though, it would make a great addition to any workshop or garage setup. Wera also offers a calibration service in the UK that you can send that wrench back to if needed.

Don't buy it if
❌ You need to torque past 14Nm or half increments: T꧃he 2-14 Nm range is only adjustable in 1Nm increments.
The Range Click Torque Wrench from Feedback 💟Sports is an updated offering from the American brand. I really like this neat, compact torque wrench🌃 and it comes in a smart travel case with 13 of the usual hex and torx bits.
The Range Click has a 2-14 Nm range which increases in 1Nm increments. Feedback is fairly specific about how you hold the wrench to torque things off so it's worth reading tܫhe for best practice. When torquing something off you will need to hold the silver end section of the wrench so use your other hand to hold the head and stabilise the tool. It's easy to do in use.
The wrench promises + / - 4% accuracy over 4000 cycles and Feedb🌳ack offers a calibration service of its own. This is a pleasant torque wrench to use and iꦍf you like the size and look of the Effetto Mariposa option above, this will provide a similar experience for a lot less cash.
The case is a little on the large side to carry on rides, and it's probably overkill. But the size of the unit overall makes it ideal for taking to events of all kinds, it's compact and neat and won't take up a lot of space. I like its in-hand fe🗹el and for the price, it's a really attractive option.&nbsღp;

✅ You want a multi-tool that can torque things too: The tool comes with loads of bits, a chain breaker and a ratchet tool making working on the bike mu𒐪ch easier.
Don't buy it if
❌ You prefer your torque wrench to 'click off' when the desired torque is reached: We prefer having a tactile click when using a t♛orque🐻 wrench.
The Topeak Ratchet Rocket Lite NTX + (phew!) is made up of a useful and well-thought-out range of tools kept in a 🍎neat velcro case. Included is a neat ratchet, chain splitter tool, 11 hardened steel hex and torx bits and a pre-set torque attachment that covers a 𒐪;2-6Nm range. Ideal for working at home, or for travelling with, the case is also small enough that I can carry it in a cycling jersey pocket if required. It's the sort of tool that would be perfect to take on a trip if you need to work on your bike upon arrival.
You could pretty much build a bike with this kit, the 1/4" ratchet is extendable and has a reversible head and nifty thumb wheel. I like you can add a hex bit to the other end of the ratchet too, I recently found this useful when installing disc rotor bolts.&🧸nbsp;
The torque attachment is useful and covers a 2-6Nm range, so this will be ideal for setting seatpost heights or adjusting handlebars. It doesn't click when torque is reached, you need to visually align the dashes on the unit so this is worth bearing it mind. There is a 2-year warranty and pre-set torque accuracy is + / - 6%. This is🌸 an ideal tool to carry or have at home to make roadside adjustments and torque bolts off, it probably won't be quite as accurate as a full-blown torque wrench but if you need a smaller all-ro💯under, this is a great option.

Don't buy it if
❌ You can't see yourself needing to torque anything out on the road or at an event: The torque adapter doesn't offer any additional functionality beyond its limited torque abiliti✨es.
The Topeak Nano Torqbar DX is another great portable option and my go-to for carrying on the bike, especially for road rides thanks to its small po꧅rtable size and cl🔴ever inbuilt tool storage.
It comes with three pre-set torque limiters of 4, 5 and🤪 6 Nm and a selection of bits in a neat plastic case.&𒊎nbsp;You then add your desired limiter and hex bit to the tool body.
What I like is the fact you can just carry the most relevant torque limiter for your bike and two hex bits inside the handle, making for a really compact setup for your saddle bag or jersey pocket if you want the ability to tꦗorque things like seatposts or bars out on the ro🔥ad.
The torque click is easy to miss though, so you will need to get a feel for this starting off to ensure you don't miss it.&nb😼sp;
ܫIt's worth spending as much as you can afford on a torque wrench from a manufacturer that provides calibration documents or lists the calibration standard adhered to. This means you sho🥀uld end up with an accurate tool.
Aside from that, work out the max torque rating to be found on your bike(s) and work backwards from this. You may need one or two torque wrenches to tackle everything, and pay at♕tention to whether you have any hard-to-reach or awkwardly placed bolts that may be hard to access; this may dictate the torque wrench size you go for.
Also worth considering is drive size, if you have a socket set of 3/8" hex bits already, investing in a 3/8" drive torque wrench means you can do a lot more with your hex bits and sockets and use them with your new wrench for example, although you can of course buy convertor sockets ꦍor the appropriately sized tools to get around this.
It's also worth mentioning a bike shop will be able to torque everything on your bike to spec for you if you don't think you need a wrench at home. If you aren't sure, be confid🤪ent to go in and ask for a torque check on your bike/s.
What is torque?
Torque is the twisting force applied to an item. In the case of bike torque wrenches, that's the bolts and components that hold your bike together, but you'll also find torque numbers (much larger ones) mentioned in relation to the turning force delivered by the 澳洲幸运5开奖官网在线查询开奖结果:best e-bike motors.
Torque on bikes is almost universally measured in Newton meters💮, abbreviated Nm, although there are other units like in/lb, ft/lb or kg/cm. Make sure that your torque wrench works in Nm to avoid having to convert values each time you use your tool.
Nearly every bolt or fastener on a bike will carry a torque rating specified by the manuf🌞acturer. Torque is the measurement of rotational force that is applied to an object. When we tighten down a bolt we stretch the threads creating friction, which prevents the bolt from coming undone. Too loose and the bolt or screw may work free, but too tight and we may end up causing damage.
Is one torque wrench enough?
In order 🃏to be able to torque every component to spec on your bike you're probably going to need two torque wrenches. Though this isn't a hard and fast rule.
The torque range of components across a bike normally ranges from 3 Newton metres and tops out at around 40-70nm depending on the component in question. Most wrenches won't cover this range so most people or shops end up with a smaller torque wrench for, you guessed it, the smaller stuff and a larger torque wrench to cater for things like 𓄧cassette lock rings and crank arm bolts. A smaller torque wrꦆench will also allow you to easily access smaller bolts that are potentially hard to reach such as brake calliper bolts and awkwardly placed seatpost clamp bolts.
Is a preset torque key good enough?
For smaller jobs on your bike, you may be fine with a pre𓂃set torque key rather than needing an adjustable torque wrench. Many small bike bolts specify a torque spec of around 5Nm, so a torque key preset to this value will really help you out. Some torque keys come with multiple fixed-value torque heads, so you'll be covered for other values too.
It's worth noting that not all pre-ꦐset torque wrenches can be recalibrated and do have a shelf or cycle life. So if you have been using the same unit for years it's probably good practice to replace it with a fresh one. Otherwise, you may be unknowingly over or under-tightening bolts.
Where's the best place to buy a torque wrench?
Don’t be afraid ꧅to look beyond cycling brands. Torque is certainly not specific to the bike industry, there is a whole range of torque wrenches on the market, what you should look for is a quality wrench that has been calibrated to the relevant ISO standard so you know it is accurate.
For bikes that means torque ranges that make sense for the bolts on a bike and it means scales rated in Newton metres. Purchasing something designed for another industry might be cheaper but could require constant conversions. Torque is torque though; as long as you find something that works it doesn't matter too much what it's𝔉 marketed for.
How do you use a torque wrench?
.
Once you know the torque rating of the bolt you want to tighten, set the torque wrench dial or gauge to the relevant rating and begin tightening the bolt. Ensure the hex bit attachment🉐 is sitting straight fully engaged with the fastener you are tightening. Once your desired torque is reached the wrench will audibly 'click', or if electronic, 'beep' letting you know the desired torque has been reached. You will also be able to feel a physical click in the wrench itself when the desired torque spec is reached. Resist the urge to redo the bolt, you only need to torque it to spec once.
What are the most common types of bolts found on bikes?
The bolts or fasteners most commonly found on most modꦡern bikes are Hex and Torx bolts. Hex bolts, also commonly referred to as allen key bolts have a six-sided head. Torx bolts have a six-sided star-shaped head and are visibly different to Hex bolts. In case you weren't sure, most of the regular bolts on your bike will be Hex bolt൲s.
Bicycles don't require big nuts and bolts. The most common size hex bolts found on bikes are 2mm, 3mm, 4mm, 5mm, 6mm, 8mm and 10mm. If you're looking for a torque wrench with included bits cꦯheck what your bike uses and buy the one with the most relevant bits for you. To be honest, most generic torque bit sets will cover a lot of common jobs on a modern bike.&nbs🃏p;
The Torx bolts most commonly used on bikes a🐎re T15, T20, T25 and T30. Common uses for these sixes are disc brake rotor bolts which are often T25, and Shimano chainring bolts which are T30. Again, if you are shopping for a torque wrench with bits check what Torx bits come with it.
What type of torque wrench is best?
Some torque wrenches ar𓄧e electronic and some are mechanical. There's nothing that makes one inherently more accurate than the other but there are reasons you might choose one or the other. The main argument for mechanical is that they don't need🍌 batteries. You never run the risk of reaching for your wrench and finding it dead. Also, torque wrenches can last a very long time and LCD displays don't have the same staying power as a precision metal tool.
Electronic wrenches offer more flexibility and information. If you hav🐈e a need✃ to measure different units an electronic torque wrench lets you easily switch between them.
More useful to most people though is seeing the torque as you approach your setting. It can feel comforting to know if you are getting close and loud alarms with blinking lights make it obvious when you've reached your target. It's also nice to be able to p💟recisely set an exact🌠 number and have it easy to read. The downside is that the dead zone and click of an analogue wrench when it reaches the set value is easier to feel and electronic wrenches don’t have that.
Electronic or analog torque wrench?
Fundamentally the way that analogue wrenches and electronic wrenches work is different. Analog wrenches use a spring and when you get to the correct torque there's a release of pressure along with a click and some amount of dead zone. Digital torque gauges work the way that a power meter doe🀅s, with strain g൩auges. What that means in practical use is that there's no release of pressure and dead zone in electronic wrenches. But their batteries can run flat, which may catch you out from time to time.
Elec﷽tronic torque wrenches also have a slightly different feel to mechanical units that can take some getting used to and it can be slightly harder to feel the torque or 'tightness' of a fastener as you tighten it with an electronic wrench. In our experience, this can ma𝔍ke you doubt yourself sometimes, and I personally prefer the feel of an analogue torque wrench. If something feels off, don't just blindly proceed, stop and check your work.
Do torque wrenches need maintenance?
Torque wrenches are precision tools for measuring torque, not general-purpose wrenches or ratchets. If you use your torque wrench to undo bolts, you risk pushing it out of calibration and or damaging it. Always use another 🦩allen key or regular wrench for loosening bolts and only use your torque wrench for tightening to spec.
For the same reason, you also want to be sure to zero the wrench when you finish using it. Leaving the wrench spring in tension during storage will affect calibration over time. It only takes a moment to set the wrench to the lowest sett♒ing before storing it and it will make sure you get the most precision out of an expensive tool.
Most manufacturers recommend a calibration check yearly. This is not particularly expensive to get done and will ensure your wench is still operating in the correct range of torque. However, I used my own torque wrench day in and day out for 💛a few years, dropped it and left it wound on more than once, and it passed a metrology lab calibration check and was still in spec, so don't fret if you don't calibrate your wrenches for years. I♔t's best practice, not the law.
Try to avoid dropping your torque wrench and always store it in its case or bag. Temperature extremes can also affect the accuracy and a few practice 'clicks' befor🌸e you begin working will provide more accurate results as the spring in your click-style torque wrench warms up.
Do I have to use a torque wrench?
You don't have to use a torque wrench on your bike but♉ it is advisable and best practice to do so.
Using a torque wrench is the difference between hoping something is ri♊ght and knowing it is, this is especial𒉰ly important if you are working on bikes for other riders or customers.
Using your own feel when tigh🌳tening bolts will get you pretty close (if said feel is decent), but ultimately it's just a guess.
A torque wrench eliminates any doubt and co💧nfirms your components won't be damaged or vibrate loose on your bike. In the event of a warranty issue, you'll be in a bett𝐆er position.
How do I find the torque rating of a part?
Components like handlebar stems, seat post cl♌amps and crank bolts often will have torque ratings listed on them somewhere by the manufacturer. Bu🌞t often things like derailleur bolts and brake pinch bolts will all have torque ratings but you may have to look them up.
Manufacturers' websites will have torque specs listed, but Park Tool also has a of torque🦂 specs here for you🍰 to reference.
Should I grease the threads of bolts before I torque them?
An assembly compound such as grease or anti-size seize etc is often recommended by manufacturers when assembling components and𒁏 tightening bolts.
Friction between dry threads can lead to inaccurate torque readings. It's best to adhere to the manufacturer's specs if you are unsure, but grease and/or anti-seize is a good idea on nearly every threaded fastener. if you ar🅺en't sure, pick up the phone and ask the manufacturer or retailer for best practices.
Torque terms glossary
Torque Terminology Glossary
Some specific terminology comes with torque wrenches. We are going to outline some of the common terms in this guide before we begin so you can follow the buying advice easily and understand everything. We know it can be confusing sometimes when you keep reading a term, bu🅰t don't completely understand what it means or refer too.
Torque: A way of measuring the force applied to an object that moves.
Newton metre (Nm): A measurement of torque
Square drive: The square connection on the torque wrench that can connect with a range of sockets or tools
Bits: The small Hex or Torx tool bits are used to work on the bolts on your bike.
Convertor Socket: A socket that for example allows you to fit 1/2" sized sockets to a 1/4" drive tool, allowing the use of a wider range of tools
How we test torque wrenches
Research:
Testing for this guide starts with res💦earching and reading about as many of the relevant torque wrenches on the market as I can find. After receiving a test unit I then went back to the manufacturers or distributors with any additi😼onal questions I had.
Initial inspection: I inspected all of the torque wrenches on arrival fo꧂r any defects or quality issues and photographed them. I also take into account packaging, for example, if there is a lot of non-recyclable plastic or unnecessary paꦅckaging.
Workshop testing:
I then use and test all of the torque w🦹renches we review on a range of different bikes, components, and service jobs to see how they operate. The larger wrenches were useꩲd in my home workshop and the smaller compact ones I travelled with or carried with me on rides.
Repeatability and consistency:
I repeatedly performed lots of jobs that you would expect a torque wrench to be used for by a bike mechanic or home user. From torqui💖ng stem and seat clamp bolts tཧo spec to torquing chainset spider lockrings and larger crank bolts. It's important to repeatedly work with and use them tools, a single test may not be a true indicator of performance.
Tom joined the Cyclingne🍨ws team in late 2022 as a tech writer. Despite having a degree i🦹n English Literature he has spent his entire working life in the cycling industry in one form or another. He has over 10 years of experience as a qualified mechanic, with the last five years before joining Cyclingnews being spent running an independent workshop. This means he is just as happy tinkering away in the garage as he is out on the road bike, and he isn’t afraid to pull a bike apart or get hands-on with it when testing to really see what it’s made of.
He has ridden and raced bikes from an early age up to a national level on the road and track, and has ridden and competed in most disciplines. He has a keen eye for pro-team tech and enjoys spotting new or interesting components in the wild. During his time at Cyclingnews, Tom has already interviewed some of the sport's biggest names including Mathieu van der Poel, Tadej Pogačar and Alberto Contador. He's also covered various launches from brands such as Pinarello, Ridley, Specialized and more, tackled the Roubaix Challenge sportive aboard his own rim-brake Cannondale SuperSix Evo, tested over 20 aero helmets in the wind tunnel, and has created helpful in-depth buying advice relating to countless categories from torque wrenches to winter clothing.
