another chain line problem - 2009/11/15 23:38
i have chain line problem and i would be please with some input.
Okay so i have an All City crankset, it has a 110 spindle length. so i also bought a 110 origin 8 BB to use with it. i used to have FSA Vero crankset that has a 103mm spindle and a BB that had a 103 spindle as well.
It looks like my cranks are sticking farther out than my sprocket. The chain is making a lot of noise and sometimes i can see the chain "snap" into place on the teeth of my cog. My chain is binding at certain angles of the cranks (cause they are usually not cocentric) because of the chain line, I believe. By pedaling with my hands I can feel that the drive is very inefficient and will sooner wear my teeth and chain. I know my chain is not too tight, there is enough slack and tautness. the only places where it might be too tight is where the chain is binding due to the chainline.
I know its not my new crank and BB (i might be wrong, tell me) because if i have a 110 BB and 110 crank i should be fine as long installation is right (i will expand on that). It should only stick out of chainline if ummm you have a short spinder length on your crank and you are installing onto a longer spindled BB.
I tried Sheldon's suggestion on chain tension but it barely helped. (http://sheldonbrown.com/fixed.html#tension)
So I thinking that since I dont have a torque wrench, I used a regular 8mm allen to turn my crank bolts. In doing so, I think that maybe i didnt screw it in enough because i can see a little spindle left. I thought it was normal untill i considered my chain line.
I have provided some pictures and in advance I am sorry for the cell phone low light quality but it is still worth looking at.
