Torque wrenches

simonp123

I've decided I need to get a torque wrench for use on the bike after my bars coming loose the other day :oops: Obviously my hand calibration is not what it was
What torque range would need to cover all (or most) bike fittings?

You can get a bike specific torque wrench which shud cover just about everything, prices vary from about £30 upwards so shop around.

Seems like a decent wrench for the money.

A torque key should cover most things on a bike ............ and it's cheap and easy to carry around

fyi
take the accuracy of a torque wrench with a pinch of salt

but the smaller the usable range the better it will be, but digital is the way to go these strain cells will stay accurately for longer, than some friction based design, but the price is mental, really

that micrometer 1 looks like a winner, is there a 1/4" option

I can get 50-60% off Sealey list price, so can probably get it even cheaper

Yes agreed about the strain gauage ones. I was working on doing the electronics on one for Britool a few years back. They do tend to be on the pricey front though. I think we have one somewhere, but it is about 3 feet long so probably OTT for a bike

Hmm, our discount is off the list price, which would in fact make it MORE than those prices. List is £88.74... I need to see what price we can get it at. I think that selling on would break our trade agreement though, sorry!

Absolutely. I used to work on overhauling circuit breakers in a power station, where everything had to be set to exacting tolerances. We had some staggeringly expensive tools, but it was common practice to set the torque wrench using the dial, then chekc it's callibration on a torque gauge, re-adjust, re-check etc etc until the wrench was tripping at the right torque value, and keep checking the callibration every hour or so.
Even a really expensive, monye-no-object torque wrench could be showing settings that were a world apart from what it was actually set to.

Tights tight, too tights fked!, works for me..

I got a cheap one off the bay, 18 del, it's 20-200 inch pounds, 1/4" drive then bought a nice driver set of hex and tx sockets for it. The big blue cycle repair book quotes most stuff in inch pounds anyways, also, if you have the net, not hard to find a conversion. From reading, torque wrenches are a little hit and miss anyways, but it is reassuring to know when to stop!! (Don't quote me on this when I post about how my mech flew off and put me in a wheelchair!
