Re: [ST] chain

[Colt4530 <colt4530@xxxxxxxxxxx>]

I've already thought of that and have a 17 tooth front to put on. 
However, I noticed I only have one "spot" of chain adjustment left and 
hoped to gain some back with a larger rear sprocket.  I also wanted to 
get more than 5% increase in RPM.  That's why I started looking at +3 on 
the rear, or 7%.  I borrowed a friends Mechanical Engineering Handbook. 
  Maybe it has enough information to calculate the chain length difference.
