Description
Description
Our revised XTR rear derailleur shifts gears as smooth as butter and keeps the chain on the teeth, even when you're thundering down the poisonous trail or conquering steep climbs. By increasing the number of pulley teeth from 11 to 13, we have also reduced friction.
Larger 13-tooth pulley
Lower preload in the rear derailleur in the lower gears to avoid excessive chain tension in these gear steps
Additional stop on the rear derailleur swingarm
