My fairly new epic wc expert came with a 32T chainring, but I was wanting to go to a 34T. I find my self in the small cogs a lot especially on the DH which leaves a lot of chain slap. I have 200 miles on the bike to date and haven't ever been in the 42t cog yet, but not wanting to swap cassettes. Anybody swapped yet? if so what size and brand did you go with?
