Ritchey Torque Key 4mm 5Nm

Great little tool for making sure any 4mm bolt is torqued to 5N.

Great for everything on your bike that requires a torque of 5Nm.

Hummed and jawed at whether I should get one and when it came on sale I snapped one up! Best price on the net!

I saw this used at the bike shop so had to have it. Puts proper torque on carbon bars without over-tightening.

In the past I have wrecked a fancy pair of plastic bars by tightening the stem too much, and wrecked my knee when the plastic seat post slipped because I hadn't tightened the collar enough. I now have a torque wrench that I can take on the bike that allows for adjustment of all my carbon reinforced plastic bits and pieces without worrying about breaking anything. Most of the screws I am dealing with call for a torque of 6-nm. So far nothing has slipped. The only shortcoming is that you cannot use it with different size bits.

Easy to use. Grip is hard to hold with big hands. Bit is not interchangeable.
