9 of the best torque wrenches for bikes — get your bolts to just the right tightness

Why you should use a torque wrench to avoid expensive and dangerous over-tightening

With a torque wrench you can get the bolts on your bike as tight as they need to be and — importantly — no tighter. The best torque wrenches for bikes cover the relatively low tightness requirements of bikes and are easy to use.

Why is using a torque wrench to get the tightness of your bike's bolts right important? Too loose and you run the risk of a bolt coming undone, too tight and there’s the danger of causing serious damage to your bike and, as a result, to yourself. Over-tighten a seat clamp, for example, and you could ruin a carbon-fibre frame.

  • Bike-specific torque wrenches provide just the range of tightness most commonly found on easily-damaged parts like seat post and handlebar clamps

  • Click-type torque wrenches are the most common kind, alerting you with a click when you've reached the set tightness

  • The best torque wrenches come with factory certification and can be returned or recalibration so you know they're doing the job perfectly

9 of the best torque wrenches for bikes

You’re too smart to trash a component by over-tightening it? It’s easily done. The mechanics at your local bike shop will tell you about people who’ve cost themselves a lot of money by getting it wrong. Torque wrenches aren’t exactly cheap but buying one could save you a lot of cash in the long run.

You'll also need a torque wrench to install some power meters so they provide accurate measurements, though this is less common than a few years ago.

The amount that you should tighten a bolt varies between components, so always check manufacturers’ recommendations.

This Shimano Ultegra crank, for instance, comes with the instruction: “Each of the bolts should be evenly and equally tightened to 12-14N·m by torque wrench”. The N·m stands for Newton metre.

Torque bolts - 2.jpg

This seat clamp requires 4N·m.

If you're wondering what a Newton metre is, it comes from the definition of torque. A torque is a rotational force. Force is measured in Newtons, as you'll recall from GCSE physics. Torque is the force multiplied by the distance between the point where it's applied and the centre of the bolt. You get a torque of 4 Nm by applying 4N to the end of a spanner a metre long, or — if you don't happen to have a set of stupendously large spanners — a 40N force on a 10cm spanner.

The right torque for a particular bolt depends on what it's made from, what the parts it fits into are made from and — if it's part of a clamp — what the thing it's clamping is made from, among other things.

Torque wrenches have become a must-have in the last few years because there's so much carbon fibre and very light aluminium in modern bikes. Clamps around carbon components can easily do damage if over-tightened, so a torque wrench is essential if you're handling such gear.

A torque wrench is also useful for big jobs, when you may not realise just how tight something needs to be. Square taper cranks, for example, typically need around 40 N·m, which is surprisingly hard to achieve without a long spanner.

Torque wrench types

BBB TorqueSet Adjustable Torque Tool .JPG

Different torque wrenches work in different ways, but one common type allows you to set your required torque by turning a knob at the end of the handle. This one (above) from BBB costs £52.48. You fit the appropriate head, then turn the wrench until a distinct ‘clunk’ tells you that you’ve reached the correct torque.

To maintain accuracy, manufacturers of adjustable click-type torque wrenches usually recommend you send the tool back to the factory to be calibrated after a certain amount of use: check the manual for your tool's particular requirement.

Birzman Digital Torque Wrench.jpg

If you can't live without an LCD display, then there are torque wrenches that'll feed your desire for digits. You can either read the torque from the display as you tighten the bolt, or set a target torque and it'll buzz and flash a light when you reach it.

Park Tool PTD-4_002.jpg

One other option is to use something like this Preset Torque Driver from Park Tool (£39.99). This one allows you to tighten 3, 4, 5mm and T25 bolts accurately to 6N·m, clicking when you’ve reached the required torque. Drivers set to other torques are available.

Park Tool Torque Wrench TW-1.jpg

You might also run across a beam type torque wrench like the Park Tool TW-1, above. This indicates torque with a pointer that simply indicates how much the tool's main arm has deflected as you turn the bolt. Beam wrenches are incredibly simple, very tough and don't have to be sent back to the factory to be recalibrated. If the pointer isn't on zero when the wrench is at rest, you just bend it until it is.

However, you can't set the torque in advance and get a satisfying click when you reach it, so beam-type wrenches have all but disappeared. Park no longer makes the TW-1 or its big brother, the TW-2.

Topeak Torq Stick — £79.49

2020 Topeak Torq Stick.jpg

The Topeak Torq Stick is compact, very nicely made and easy to adapt to most fastener types with its magnetic 1/4in drive. Running from 2-10Nm, it's a great way to ensure important bolts are tight but not dangerously so – especially important if you run a carbon bar or seatpost. The five supplied bits are basic and disappointing, though, and if portability isn't important you can get much cheaper wrenches.

The Torq Stick adjusts from 2-10Nm in 0.25Nm steps, and is certainly accurate enough for bicycle use. It's also enough torque for most components, such as bars, stems, brake and shifter clamps, drivetrain parts and most bits of disc and rim brakes. It's not enough for cranks, bottom brackets or pedals, though.

The scale is etched clearly alongside a physical indicator, so it's easy to read and should stay that way. The aluminium casing has a slightly satin anodised finish that's pleasing – and comfy at maximum torque – while the adjuster is grippy and impossible to twist accidentally once set.

Merida Adjustable Torque Wrench — £26.99

2020 Merida Adjustable Torque wrench.jpg

A no-frills T-shape handle design, Merida's Adjustable Torque Wrench is the perfect tool for quick and easy bolt tightening. It has three torque settings – 4, 5 and 6Nm – and with the 3, 4 and 5mm Allen keys, as well as a T25 Torx key, it'll cater for most common bolts on a bike. Neatly, all keys bar one are hidden inside the case. It's a good price too.

The chunky T-shape handle makes it easy to hold the torque wrench firmly, and its relatively stubby nature means you can tighten bolts easily without worrying about the key slipping inside a bolt head.

Adjusting the level of torque is easy – a dial on the top allows you to do this on the fly – although I found it slightly ironic that you need a separate 6mm hex key to adjust it, which sort of spoils the ease of having everything you need in the one unit.

Norbar 13702 Torque Screwdriver — £115.00

norbar 13702 torque screwdriver

Your classic torque wrench is, in effect, a sophisticated spanner handle. But a lot of bike parts don't need the high torque you can reach with a spanner, and for those applications the easy turning of a screwdriver handle is more convenient. The 13702 screwdriver has a range of 1.2 to 6 N·m, and can be adjusted in 0.1 N·m increments.

Norbar is a British company that specialises in torque measurement. The 13702 screwdriver comes with a calibration certificate, and if you suspect the device has drifted off, you can get it recalibrated.

Effetto Mariposa Giustaforza II Pro — £148.99

Effetto Mariposa Giustaforza II Pro.jpg

Effetto Mariposa was one of the first brands to offer a high-quality, high-precision torque wrench specifically for bike use. This Pro version has a two-way ratcheting head for speedy tightening, a handy addition to the original's fixed head. It's not cheap, but it has a very useful 2-16 N·m range, it's very accurate and it oozes class.

If you can live without the ratchet, or you need to get at bolts in very confined locations, the standard Effetto Mariposa Giustaforza II is £100.49.

BBB TorqueFix BTL-73 — £49.99

BBB TorqueFix BTL-73.jpg

Not as sophisticated as the Giustaforza, but much, much cheaper, this is a decent generic torque wrench at a very reasonable price. There are several very similar tools available: the X-Tools Pro Torque Wrench and Pro Bike Gear torque wrench are almost identical. Buy whichever you can find cheapest.

Topeak D-Torq — £149.99

topeak d-torq torque wrench.jpg

The Birzman digital wrench we mentioned earlier is no longer available, but this Topeak torque wrench with a digital display is very similar. It has a ratcheting head, a range of 1-20 N·m and can be set in 0.01N·m increments. To be honest, that's a tiny bit silly. It's hard to imagine needing more than 0.5N·m precision, but it's amusing for geek points.

If you need more oomph, the £168.53 D-Torq DX has a range of 4-80N·m.

Park Tool ATD-1.2 — £71.998

Park Tool ATD-1.jpg

Most bike-fettling jobs that really call for a torque wrench require fairly low torque values, like the 4-6 N·m range of the Park Tool ATD-1.2. It's quite expensive for a limited-function tool, but does what it does so well that it's very highly regarded.

Ritchey Torque Mini Tool Key Set - 4N·m or 5N·m — £20.98 - £23.84


Ritchey popularised the idea of a single-setting torque wrench with its first Torqkeys, but they were also supplied with just one hex size, which was fine if it was the one you needed, but a bit limiting if not. The latest version bundles a selection of useful bits with either a 4N·m or 5N·m body. Moulding a driver for a Shimano Hollowtech crank cap into the handle is a nice touch.
