how to move bb axle, for fixed gear.
I am trying to build a fixed gear. How do you adjust the bb axle?
thanks in advance |
Adjust the BB axle... what do you mean? Are you trying to clean and regrease it? Are you trying to move it side to side (adjust the chainline)?

I am trying to move it from side to side to adjust chainline. It is a nonsealed 3 piece bb

If you need to adjust the chainline precisely, you'll probably have to get a new BB spindle (cheap these days, most LBSes would probably give you one for $5 or something). The other option is to get a spacer which sits in between the BB cup and the frame on the right side... but that will only allow you to move the chainrings further OUT, not further IN. |
thanks, i'll try a spacer. I only need to move the chainwheel slightly to the right.

I think it may need a bit more than that. What do you recommend using as a spacer?

I'm a bit surprised that you have to move the chainrings AWAY from the frame. With most converted fixies, I find that the chainrings need to be moved CLOSER to the frame to match up with the chainline of typical track cranks. |
