Yo quick question.

I'm upgrading the drivetrain on my Cougar and thinking of going full Ultra 6800. However, I've fallen in love with the DA 7703 (time trial) chainrings ever since seeing them on Dick's old Cannondale.

They came in 54/55/56t and I've found a 54 for a reasonable price. However the 6800 front mech says it will only accommodate up to a 53.

Don't know if this is a daft question as on paper it won't work - but will the extra 1 tooth really make the difference between it functioning and not? Or could I get away with it with tinkering?

These?

6800 should do a 54T - band or braze on though? It's just gonna be height you need to worry about. Single ring setup or using a big inner ring too should be ok, ~10T gap.

Braze on. Normally ride 53/39 so would like to keep the smaller ring at 39 if possible.

Alternatively I could just go full 7700 as it would be period correct, but I'm the only guy on my team running 9 speed still...
