Torque wrench

nels

Hi all,

can anyone advise on what range NM i should be needing from a torque wrench for the majority of home mechanic activities. ?

thanks in advance

I use one that goes to 25NM I find its the smaller torque, i.e stem bolts that you always over do and snap.

Anything over 25NM I can usually get a feel for.

I have 2 - Pedro's beasties...one got to 18nm and the other goes to 32nm (I think)...which seems to cover everything I need them for until I got my new bike...and my crankset needs tweaked to 45Nm (I think)...anyway, at that sort of tightness, I just wait for my knuckles to almost turn white and I stop!

5 - 25NM should cover most things on a bike, anything over that is just efin tight

B&Q do one for £25

Small stuff, the small torque wrench. Big stuff, the big torque wrench. Simple :P

i.e. small things like rotor bolts, calliper bolts, stem bolts, anything screwed to the handlebars. Basically little bolts in the main. Mostly about 5 to 10Nm.

Big stuff - cassette lockring, cranks, pedals, BB. These can all be in the 40Nm+ range.

But up to you whether you feel you need them or can be confident in your own force and know how tight stuff should go. I just like to be sure I'm doing stuff up enough and not too much that it won't come off again or break.

Mainly I prefer the big wrench. Small stuff I can do it without, but doing up cranks and stuff I'm always surprised how far I have to go and without I'd probably not do it up enough and something might come undone.

Thing to watch is with the socket types, the high torque wrench is not accurate at the bottom end, so you need the small wrench too. Also they're not so accurate with opposite threaded stuff.

true was shocked when i did the bb on my cough cough scott shhhhhhhhhhhh road bike :oops: just how high and how much force the 50-65 nm was... i only got a big torque wrench it only goes as low as 20 nm. need to get a smaller one.. but need to get a job first to afford it... unless the jobcentre will buy me one, as i'm unemployed,,
