I've got 3 torque wrenches, but don't use them for bike work, relying on
calibrated wrists.


Seriously, you need to get a feel for tightness, after all by the side of
the road you won't have your torque wrench handy. I can only think of one
nut/bolt on any of my bikes where rigorous attention to tightness is a
necessity, and that's the rear wheel axle for horizontal drop-outs. Maybe
seat pillar too, but with my sylph-like figure (cough) I don't need to
worry.

That'll be OK for cranks, but too big & heavy & inaccurate at low settings
for just about everything else on a bike. But you don't need a torque
wrench for anything else, IMO.

I once read an article in Cars & Car Conversions where Dave Walker (big name
in the car tuning world - actual race cars etc. not max power tat) had gone
along to a torque wrench manufacturer and they'd had a couple of bolts
mounted on stress gauges. They asked for a volunteer to do up a bolt with
the torque wrench, so everyone could see how accurate it was. He went and
did up the bolt with the torque wrench, then asked for a normal spanner and
got the torque dead on by hand.

That's fine if you've used a torque wrench and know what you're aiming for.

If you've never used a torque wrench, then just how tight should the below
feel (using standard sized spanners/allen keys)?
5-7 Nm (eg front mech and cleat bolts)
9-11Nm (eg stem clamp bolts)
35Nm (eg pedal to crank)
50Nm(eg bottom bracket)
(from http://www.sgr.me.uk/mountainbikingmeuk/torque.html)

Thanks, Peter

The only time I ever used a torque wrench on bikes was when rebuilding
suspension forks, for that sort of application I think this would be
more appropriate:

but the torque range is still a bit high. Most other fastenings on a
bike are pretty easy to tighten "by feel" if you have mechanical
sympathy.

Surely you want this one http://sheldonbrown.com/tork-grip.html :-)

Seriously I can;t really think of a time when I'd use a torque wrench,
rather than a spanner. when it's tight, it's right.

Torque Screwdrivers are also available (used a lot in electronic
and mechanical production environments). These have much lower
torque ranges than a wrench.

RS Components do a range, but many (not all) have no dial and
have to be set up using additional measurement equipment.

Just tight

Just tight, then small amount of pressure more


35Nm (eg pedal to crank)


Well tight


50Nm(eg bottom bracket)


With a normal sized spanner quite an effort but not putting your full
weight on it.
