I have an XD triple crank that I intend to install on a build for Mrs Banzai.
I mounted it with one BB, and I noticed that the left crankarm sat considerably (several observable millimeters) farther from the frame/chainstay than did the right. I tried with a different BB, you know, just in case there was something wrong with the first. Same problem.
Then I took the digital calipers to the arms. The left, at apparent equal insertion, measures 1mm "tighter" than the right.
I went to the LBS to gripe (I bought it from them) and they started telling me that crank symmetry is no big deal, it doesn't have to be symmetric, then proceeded to point out several bikes in the shop with asymmetrically spaced crankarms...all of them with Sugino square taper cranks.
So. Are they right? Or are Sugino cranks not as good as they're cracked up to be? Or do I just need to learn to accept such imperfection in this build?
Replies are appreciated.
