Sherpa 198A Gearing Sprocket Sizes

Featured Replies

Advice please, the Sherpa 198A I'm refurbishing currently has 12T front and 40T rear sprockets that are very worn and to be replaced. I didn't get chance to ride the bike before stripping down, so is this a reasonable ratio for a complete novice rider? ⚙️

Cheers! 

That's  reasonably tall gearing, standard is 11/39 and most around here are running 11/40 to 11/42 just to get a little more control in the tighter sections.

A good idea would be to try 11/40 first and see how it goes. I currently run 11/42

 I currently have 11/43 on my 199A, 42 is probably easier to find and should work fine.

Thanks, everyone good advice and much appreciated. I think 11/42 sounds favourite!
