So I was convinced to go 12sp for my TT bike and need a bigger chainring but have pretty much zero options I can find. Looking for a 58T (at least a 56T) for Shimano 12sp. Has anyone found anything out there that’s compatible?
Alugear, Garbaruk to name a few. The Alugear looks really nice with the matching cover , Rotor goes up to 56 for a 2x but I guess with wanting a 58 you are looking at a 1x option.
I just rode the Aten at 24 Hour World TT champs. Definitely take a look at their site as there are marginal gains there. Fitment is gorgous and the big NW teeth have been flawless for me over 1000+ miles. No chain catcher needed here!
130bcd non hidden bolt Quarqs can fit Aten rings fine, as well as 110bcd 4 bolt DFour. What doesn’t work is 130bcd hidden bolt, 110bcd 5 bolt and also direct mount (but 107bcd 4 bolt is okay).
Sure thing. The only issue we’ve found with 110bcd 4 bolt cranks is the SRM Origin cranks: we couldn’t get a design to work well without it being a completely separate option (which would have been too expensive!).
Thanks for the info - I think aerocoach seems like the best option if I can get it in time.
For the 11sp chainring - you are just running the chainring as 11sp, cassette and chain remain 12sp correct? I assume the risk is some inefficiency/risk of dropping due to chain link spacing?
