It is a good suggestion to make use of a torque wrench when engaged on fashionable bikes. Fashionable street and gravel bikes are inclined to function carbon fibre parts, frames and wheels, and a torque wrench is the distinction between hoping you’ve got tightened a fastener correctly and realizing you may have.
The best bike torque wrenches provide the means to use the right amount of torque to a fastener when tightening it up. In easy phrases, in case your tightening a bolt or screw, a torque wrench is the instrument that may guarantee you may have tightened it to the producers’ beneficial spec, which is commonly, however not all the time listed on the half.
At the moment, I am trying on the M Half torque wrench, which is a extra reasonably priced providing for anybody engaged on bikes. It is a neat little instrument and set which is available in a troublesome plastic case and with seven bits included, which suggests you may hit the bottom working and use it immediately.
M Half is an in-house model of UK distributor Madison, so this instrument could also be trickier to search out in Europe or the States, although you could possibly order one. The RRP is £59.99, although yow will discover it for even much less on-line.

Design and aesthetics
The M Half wrench is available in a sturdy plastic case with two snap-lock closures. Inside is the wrench itself, which is silver with a black deal with. There is a calibration and instruction leaflet, six Hex and one Torx bit. The Hex bits are 3/4/5/6/8/10mm, and the Torx bit is a T25.
The torque wrench itself covers a torque vary of 3-15Nm, so this unit will cowl all of your commonplace handlebar, stem, seatpost bolts, derailleur mount bolts, Shimano crankset bolts, and many others. It’ll cowl a variety, however it’s possible you’ll want one other wrench for cassette and disc lockrings or larger crankset bolts. Some fasteners and headset components do have torque scores decrease than 3Nm, however they’re extra unusual.
The torque wrench itself makes use of a 1/4 sq. drive head. If numerous your sockets are 3/4″ dimension, as I do know mine are, don’t fret an excessive amount of, because the included bits will get you off and working. You possibly can all the time add extra bits or sizing converter sockets as you go.
The wrench has a reversible ratcheting head with a reasonably high quality motion, and a push button on the again of the pinnacle releases sockets effortlessly.
There’s a see-through torque scale window on the physique of the unit, and also you alter the torque setting by pushing the underside of the wrench in and rotating it. There’s even a helpful picture on the underside of the underside when you need assistance.
The torque wrench is calibrated to the ISO 6789 commonplace and comes with a paper certificates of calibration within the field. This can be a fairly stringent calibration, as I learnt when I took torque wrenches to a calibration lab, and ensures the wrench goes to be correct for not less than one yr of use, which is the interval that almost all producers advocate getting a torque wrench recalibrated. I imagine this hardly ever occurs, not less than within the bike trade. A torque wrench of mine was nonetheless in calibration after not less than two years of heavy use. Nonetheless, it is good to recollect it is a precision instrument, and it’ll pay to take care of it.

Efficiency
The hex bits will cowl all types of helpful jobs on the bike (Picture credit score: Tom Wieckowski)
This has been a fantastic torque wrench to make use of to this point. The ISO 6789 calibration offers me confidence that I am working precisely. This goes for any torque wrench, however it is possible for you to to ship it for calibration when wanted in most territories.
It would not cowl every little thing. I wanted a 1.5Nm ranking on the Canyon Grail gravel bike I just lately completed testing, for example, however for almost all of frequent jobs on a contemporary bike, it is going to show very helpful for the cash.
It is round 30cm in size, and the grip is snug and simple to make use of. I additionally just like the clear audible click on off when torque is reached. M Half recommends simply protecting the hand ‘centred on the deal with’ in use, so simply maintain the black deal with evenly to make sure correct torque.
One factor I discovered a bit of niggly at first was following the printed scale for decimal locations, the dimensions would not have entire numbers printed. As an example, it goes from 0.8 to 1.2, that means it’s a must to decelerate and take your time to reach at sure torque scores. Particularly since solely even numbers are printed on the white torque scale on the wrench’s physique. It is hardly the top of the world, but it surely’s extra noticeable coming from different wrenches, that are simpler to make use of. I received used to it rapidly sufficient, but it surely’s not the quickest means of working.
The opposite factor I’d advocate buying if you do not have it already is an extended hex bit and holder so you may torque down shifter clamp bolts, which frequently get neglected. An extended bit will even assistance on different hard-to-access bolts, like seatpost clamp body bolts, for example.
It is good to have a case included, and it retains the unit mud and grime free and provides to the worth providing once more.

Worth
I believe this instrument affords fairly stable worth. It is made in China, I imagine, and I’ve seen related trying items on supply from different manufacturers, however the ISO calibration is a seal of accuracy.
In use, the wrench has completed precisely what it says on the tin for me. The size is my solely small gripe, and as talked about, the included chrome vanadium bits and case add to the general high quality of the package deal, particularly contemplating the worth.

Verdict
This can be a good worth providing from M Half that ticks numerous containers at a aggressive value level. The included bits mean you can hit the bottom working, and the ISO calibration offers confidence. I take pleasure in utilizing it and can proceed to make use of it to work on a variety of bikes.
