Cage Lock:
With Cage Lock technology in the rear derailleur, wheel removal and installation - as well as chain installation - becomes faster and simpler. Just pushing the cage forward to create slack and lock it into place.Roller Bearing Clutch:
Roller Bearing Clutch rear derailleurs deliver maximum drivetrain stability - even through the most punishing terrain. The derailleur bounce and chain slap will be eliminated without sacrificing precision.
X-Horizon:
The X-Horizon rear derailleur's 'straight parallelogram' design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears.
