Torque Wrench

Raam

I bought a Park Tool Torque wrench and I'm wondering which
Bit Set can be used with it.

Is the Pedros one appropriate?

I can't see a Park bit set available on any of the usual suspects

I bought my bit set in a tool shop on Capel St.

yeah you should be fine with the pedros one - most torque sets come with square .25"/.375"/.5" drives, the pedros looks like it has an adaptor for square to hex which is what most small bits tend to be. Alternatively as ElT has pointed out just get one in McQuillans on capel st or similar - local auto shop/diy etc.

Pedros Torque Wrench kit dosen't have a 10mm HEX which is quite important for the cranks I think. My cranks campag are 10

Just wondering. I thought of getting a torque wrench a while back but then realised that once I had it, I wouldn't know what values to use on what parts. Is there such thing as a general guide or does every screw/nut combination have different tolerances?

Its not the bolt you need to worry about in a lot of cases, but the frame tolerance and cranks. The bolts will be steel but the cranks will be aluminium, which means you should check your frame manufacturer and drivetrain manufacturer websites, don't go looking at torque values for the bolts.

I think park tools have a list of recommended torques for various parts and brands.

I bought a campag groups set and every bolt has a tolerance via the associated guide but there are general recommendations as well

Seems here as though the Pedros torque wrench is also 1/4" drive so you should be grand. I have the same Park Tools wrench except in 3/8" drive, the Park 1/4" drive only goes up to 60in-lbs which is too small for pedals/cranks (and even my 70in-lbs seatpost), but is better for more precise measurements such as stems/handlebars.

There are general guidelines but apart from that it will often be printed on the components themselves. Alternatively all Shimano stuff for example come with extensive instruction sheets regarding fitting that includes torque information (also available on the web). There are also lists in some books such as Zinn and the Art of Road Bike Maintainence.

In my experience...
5-8nm for stems, handlebars
8-10nm for seatposts
12-15nm for cranks (hollowtech II anyway)
20-35nm for pedals

Good link, you should add it to the wiki.

id you get a key set? I only ask because I couldn't find one in McQuillian tools. I'm thinking I might just wait till the Park Tool set comes out that looks great.

Not got one yet.

I emailed CRC and they say the Pedros one linked in my first post should do the job.

Clever, but if you only want a torque wrench for seatpost, bars and stem and use 4mm bolts you can get one for under a tenner.

I need to get one for stuff like the crank bolts.

ednwireland

forgot about that ritchey one
