Default Re: Manic hub question..


The two sets of holes are for two different sprocket adapters.

I make one adapter on a 3 1/8" bolt circle, the other on a 3 5/8" b.c.

The sprockets that I ship to Pirate Cycles are drilled for both adapters.

Changing the sprocket to the other holes will not work! The sprocket will not even bolt up!

Remove the chain and spin the wheel...check to see that the sprocket is running true.

If it is then your problem is more than likely in the chain.

Provided that your hub is matched correctly with the adapter...It is virtually impossible for the sprocket to run out of true.
