>>1403105I'm running 50/34 and 11-28.
My prefered cadence is in the 110-120 rpm range, 130-150 when sprinting and 200 maximum.
Even when drafting trucks at 80 km/h I'm not running out of gears and don't tell me you're going much faster than that on your own.
Absurdly big rings are for posers, recumbents and velomobiles.
