Subject: RE: School me on torque wrenches cjohns716 - 2013-04-24 9:57 PM I've been having the same question as jmk. My seatpost is 5nm, the small screws on the stem say 6nm...is there a key type wrench like the Ritchey one previously mentioned that can be adjusted from say 4 to 10 nm? Or is the difference between the correct "tightness" of all these small parts negligible (say within one or two nm)? I've considered buying the Ritchey key at the LBS, because I have a creak coming from my seatpost (I believe), but don't want to spend the money on a 5nm wrench only to have it be useless on all the other parts. Thanks for any clarification. I would talk with your LBS mechanic on the 6Nm vs 5Nm thing, they may tell you they just torque everything to 5Nm and have never had a problem. The key is not to OVER tighten hardware with carbon, you can either crack the carbon, strip or damage the threads, or stress the components too much. I would say get the ritchey clicker wrench and use it on everything. The ritchey is probably only accurate +-10% anyway. BUT If you want to ensure all the bolts are torqued to spec, you can buy a small 1/4" drive version torque wrench that is adjustable (similar to the craftsman one). It will certainly be more expensive, but it gives peace of mind. |
