Ask 10 "racers" and get 10 different answers. The smallest I would go would be 15 up front. You wouldn't have $65-70 in both sprockets. $20-25 front, $40-45 rear as long as your don't to aluminum rear sprockets.Thats really interesting, I didn't know any of that. Thank you!
I was talking to a guy on Psychobike who is running 15/43 and said he is going through the traps on the limiter in 6th. He was saying his bike didn't leave as hard on a 16/45 as it does on the 15/43.
Seems like a 15/42 would probably be a pretty good combo and a bit more aggressive than what I have now. Just have to debate if it'd be worth the money to try the new setup or put that money towards some ceramic bearings...
Is there any truth behind running a smaller front sprocket and losing hp? I know I've got a few friends that say that but don't know how much I really believe them.
But with the smaller sprockets your rear wheel would be pushed out a little more. So if your about out of adjustment you may have to shorten the chain.
