Can one of you 2007 Demo 8 owners give me some info on:

Seat post diameter (30.9 mm?)
BB Spindle Length (113 or 118 mm?)
Rear Axle Diameter (12 mm?)

Thanks!

This should help for 2 of your questions. Not positive about the bb spindle length though...

30.9 seatpost and 10mm axle 135 spacing the bb spindle depends on what crank you use.

Thanks for the info. I'm planning to use Truvativ Holzfeller cranks and an e13 chainguide. Anyone know the correct BB spindle length?
