heavy duty shift kits?

[Sidewinder Jerry]

Any specific parts you want, or are you just looking for the whole Kit? I have some extra SBP shift kit parts that I bought when they announced they were closing and I am more and more sure I probably won't be using them.

The freewheel would be the main part. The OP is a very very large person (400 lbs) with steep hills to contend with; I was going to suggest switching the 17t sprocket out to a 20t sprocket. If he plans to use something like a Phantom 85. On the bike an 8 speed 34~13 cassette. Then it'd be like having a 90t sprocket in the rear to a 36t sprocket. I'll also have to tell him what bicycle chain, shifter, and derailleur to use.
