I have been looking into new chain and sprockets. Especially since I am still running the stock set-up with 700 miles on them. I am checking out the Ironman sprockets with a DID ERV2 chain. My question is should I stay with the stock 14/50 gearing? I run harescrambles with tight sections and also ride wide open trails at pretty good speeds. I find that 1st gear is useless. I almost never use it because it is geared so low. Even on extremely large hill climbs (in Ohio because NC doesn't have any that I have found) with no run, I never use first, 2nd all the way! Should I go to a 15 tooth counter sprocket, or maybe like a 45 or 48 tooth rear? How much of a difference will I notice? How much would this affect chain length? Any suggestions would be greatly appreciated!
