Torque wrench for bike and car

[Tin Pot]

Does anyone sell a torque wrench that covers car and bike torque ranges? I'd rather not buy two.
I understand the range would be something like 9Nm-130Nm

Cheers all,

Torque wrench? Why would you need one? <ducks head>

Take a look at http://www.cyclechat.net/threads/loctite-on-pedal-thread.151259/

Some people think you should use a torque wrench, others not....

I think it might be a bit hard to find one that covers all that range. The Sealey STW1011 goes from 7-112 Nm. I have another Sealey model and they are pretty good value for money.

Cheaper to buy a decent one for each

Yes you can buy one to cover the range that you require but they are expensive and you pay more for one that ACCURATELY covers such a wide range rather than buy 2 that splits the range and are likely to be more accurate.
The problem with covering very low to mid range torque settings is the chance of breaking/damaging the part you are using it on due to the size of the torque wrench i.e. bigger torque = bigger wrench.
If you still want one or look at a selection of wrenches here is a good guide to base your choice on http://uk.rs-online.com/web/c/?sear...9g&sort-by=P_breakPrice1&sort-order=desc&pn=1
Personally as a mechanical engineer I use 2 or 3 torque wrenches to cover that range but I didn't pay for them so cost wasn't a problem for me.

Look in MachineMart for a variety of prices. 130Nm too low for general car usage and 9Nm too high for bikes.
Agree with what @Cow Pie says. I personally have 4 and really need another 2 to reasonably cover full range of use.

\yeah, I though so. Wheels on a car and a carbon seat post are worlds apart - it was just on the off chance

From 24th March, Lidl's was holding "car care" specials. They have a torque wrench for £15.99. I bought one of them a few years ago and use it for my bottom bracket and fitting cassettes. In real terms I do not know how good it is compared to a more expensive one, but I have found it satisfactory. They may still have some in stock

For smaller jobs on the bike though I had to buy a "Giant" torque wrench as most jobs are around 5 Newtons

I wouldn't recommend a car-sized torque wrench for the likes of stem bolts. For the bottom bracket and casette it will be fine, but trying to use a torque wrench that goes up to 200Nm for small jobs is not a good idea.

Buy a bag of apples.
One apple supplies approximately 1 newton under earth's gravitational field (assuming 100g per apple and 9.8m.s^-2 gravity).
Imagine applying one apple (one newton) at the end of a 1 metre long lever (or five apples if you need 5Nm torque)
If your lever is only 0.1m long, then you need 10 times as many apples.
Simple!

I like this idea, and it does make it simple. However, a word of warning: technically this will only work with metric apples such as French Golden Delicious. All torque settings are thrown off if you use something like a more traditional McIntosh (and I've heard Cortlands give inconsistent results).
