Do you have a Torque Wrench?

What size bolts do they turn? Which size do you find most useful? Where did you get it?

I'm just looking for a small hand one, inexpensive and low Nm (5-30 or so).

Thanks!

I got one with an adapter head, that fits the Kraftwerk multitool bits. For my carbon parts.

I do, but I have it from working on my cars, so it's a 1/2 in head. I just had to find a hex bit for it to tighten up crank arm bolts, but it was impossible to find in 1/2 in, so had to use and adapter to get to 3/8. I'd suggest a 3/8 beam torque wrench: www.sears.com/shc/s/...eyword=torque+wrench , which you can get at sears, etc for about 20 bucks. I think mine's probably from Pittsburgh tools or Northern Tool & Equipment.

eta: Northern Tool has one ( here: www.northerntool.com..._200263474_200263474 ) that's the nice set it and pull til it clicks type for $40- those ones are much more pleasant to use and easier to store.

We have two - I think, one of the Sears ones like mayanorange talks about and a bigger, heavier one too. Both take interchangable hex bits. The bigger one works for some things, but doesn't have fine enough gradations for a lot of bike uses. (like tightening carbon seat posts/handlebars)

It depends what you want to use it for. Not only how accurate you need it to be, but what the range is. Torque wrenches come in various ranges, and you want to be in the middle of the range for the most accuracy. You also want to use a wrench with an appropriate sized drive for the sockets/fasteners, so that you aren't risking damage to the wrench attachment (if it's too small) or the fastener (if it's too big).

For torquing anything into/onto carbon fiber or aluminum, I'd shell out for a good torque wrench. I have a cheap Craftsman 1/2" drive beam wrench for the rear axle nut on the motorcycle. I have a Snap-On 3/8" drive click wrench for most of the mid-sized fasteners on the bikes and cars. Then I have a Consolidated Devices 1/4" drive click wrench for in-lb fasteners like valve cover bolts and anything on the bici.

A good torque wrench will last you a lifetime and potentially pay for itself many times over in damage prevention. It costs about the same as two pairs of cycling shorts (one pair of expensive shorts!) or two sets of tires.

I think I'll look into a clicking one for my carbon parts in a 3/8" with some hex attachments

I like the Northern Industrial one

Thank you for all your help!
