THM Clavicula Install
Posted: Fri Dec 14, 2012 5:02 am
I just installed a set. The instructions are detailed so I won't cover anything listed in them. I ran into a couple things so I figured I'd share my experience in case it helps someone else.
First - I noticed the threads on the BB were damaged. Nothing serious. I threaded them in by hand before installing just to be safe. Most people these days are using an 'Integrated System' but if you do have a threaded BB I would advise checking the threads. Disclaimer - I did not install the bottom bracket. I do not have a facing/chasing tool so I brought my frame to the LBS.
The installation of the cranks was pretty straight forwards. There is one thing I wanted to mention that the instructions didn't. It can be difficult to push the 'Drive side' arm through far enough to attach the 'Left hand crank'. I lightly greased the contact surface but it was still pretty stiff. I attempted to use the screw that attaches the two cranks with the disc to 'pull' the crank through. It did not reach yet. I purchased another screw, same threads (coarse) but longer by about a 1/4 inch. I was able to easily pull the crank through. Replaced the purchased screw with provided.
I realize my tip is vague. Hard to describe, but if you end up trying to install these I think you'll know what I am talking about. Hope this helps.
Cheers,
Ps. Mods - this is my first post so move if another Forum is more appropriate.
