What Torque Wrench?
« on: 30 July, 2008, 01:32:12 pm »
Wiggle have a Park Tool that looks different to the one Pumpe posted about ( BBB ).

I have carbon lovliness but also an increasing amount of light weight aluminium that has torque settings to stay within.

Which torque wrench for me?

however that one is not like the one Pumpe linked too.

More important than the torque wrench is ensuring that nuts and bolts are clean and lubricated to go on smoothly, so that you don't get a false reading due to 'stiction'.

Yep, agree with the above :thumbsup:

What about this one from Screwfix.  A bit cheaper and has a good range.

Ah we can commence the discussion reguarding a clean thread and a lubricated thread.

Does it come with a calibration certificate?  Better not to skimp on something as importatant as torque wrench.

I have that Park torque wrench and I've never used it even though I too own carbon loveliness. I'll sell it to you if you want - £20?

I have the Screwfix version already.  Got it free with my re-subscription to CycleSport mag.
But, I don't think it works.
I shall take it into the LBS and see if he can get it to work.

Just make sure you get one that works in both directions!

Indeed. You don't want to over-loosen your nuts.

Checking is quite expensive, around £25-£35 and it may not be adjustable to bring it back into calibration.

NEVER USE A TORQUE WRENCH TO LOSSEN NUTS use a breaker bar

Should be used for differing direction threads

I know it is the click when tension reached type, but that is my point, I can't get that bit to work to my satisfaction before I use it in anger on the carbon bling bits.  I will get the LBS to test it on some old steel hack of an MTB he will have out the back.

For those (admittedly rare) situations when you need to do up a left-hand-thread nut to the right (or should that be left? :)) torque.

You in London?  Just had mine checked and were found to be within 2% over all. So you can compare against mine.

Yes, well, they're okay so long as they're calibrated properly.

What about this one, at the lower end of the price scale, for the upper end of the torque range used for bikes?

10 - 80 Nm seems quite a useful range. I already have a small TW for lighter stuff.

far too heavyweight for anything on a bike except crank bolts maybe.

again 10Nm still a bit heavy unless like you say you've got a lighter one like you have.

Most things on carbon bikes have to be the same torque, i.e. about 5 or 6Nm, so consider the pre-set one that Ritchey do:

only problem might be is if you've got things which don't take an M4 bit, whether you can change it or not i don't know, but most seat posts and stem bolts are 4mm I think.

The only things for which I use a torque wrench on a bike are Sturmey-Archer axle nuts.  These are made of a soft white metal, and designed to strip before the more expensive (and hard to replace) axle.  I only use 20Nm on them.

On a car I use a torque wrench (two different ones, actually) for spark plugs (it's v.easy to strip cylinder heads) and wheel nuts (mainly to ensure even pressure on the brake disc).

I can't remember the last time I stripped a bolt or had anything come undone on the road.  Years of working with BSOs gives you a feel for when a thread is tight enough, and what different materials will take.

The bolts on stems work pretty well with the "finger tight using the wrong end (less leverage) of the allen key, then half a turn" method.
Hard work sometimes pays off in the end, but laziness ALWAYS pays off NOW.
