Spindle length for new BB

Hey everyone. I have this 1997 Schwinn Mesa that I have been building up for this winter. I have most of it done including new rear wheel, SS conversion kit, rigid fork and front brake. The only thing I have left to do as far as I know is to get a new ISIS BB and install it along with my new crankset, and a new chain too.

The crank I ended up getting is a FSA Pounder with bashguard. It is a DH 32/22T double, but I got it cheap and think it should suit me well. Hopefully it will allow me to run a 2x2. The only thing that concerns me about it is that I wanted to make the inner ring 32T and the outer 38T or 40T, but I am not sure that anyone makes a 32T (or close to that) inner ring with 64 BCD. This isn't a huge deal though. I am running 2 cogs on the rear so I can have multiple ratios.

What I need to know is what spindle length I need on the BB to make this all nice and straight. I have the Forte chain tensioner, and it has limited inward adjustments. Would a different tensioner give me more adjustability?

This is my previous thread showing some of the process, although this is before the extra cog and fork.


Thanks for the help.

Your spindle length is determined by the crankset. Contact FSA and ask them. http://mtb.fullspeedahead.com/fly.aspx
