Recommended Use

Run 11-28T when cadence control matters and shifts need to snap.
Go 11-32T or 11-34T when the grade turns brutal, just confirm derailleur capacity before you send it.
Choose twelve speed 11-30T for modern spacing with a clean top end.

Bottom Line

Pick the range. Lock it down. Start taking gears from people.
