Park Tool TW-2 Torque Wrench
Because torque specifications are now given for most parts and accessories, Park Tool offers two tough, accurate torque wrenches. The TW-2 is 3/8" drive. Includes two scales from 0-600 inch pounds and 0-70 Nm.
The scale of the TW-2 is made with increments of 5 Nm per line, and 25 in-lbs per line. Accuracy of +/- 4%.
This wrench will tell you if it's out of calibration. And then you can recalibrate it by tweaking the needle so it reads Zero at rest. It's about as accurate as a click style and quite a bit cheaper. One complaint I've heard is that it's tough to read when used on the far side of the bike. This is true. So I've marked the torque points I hit on a regular basis on the backside using Sharpie. Heck, for the price of one click wrench, you could buy two of these and steal the sticker from one to put on the backside of the other.
