- HYPERGLIDE+Ā drivetrain system enables smooth, quick, quiet and shockless shifting in both directions - no more *thoonk* when dropping the chain to smaller sprockets.
- Faster shifting -Ā gear change time reduced by ~33% vs. HG drivetrains.
- Less shifting shock means smoother, more efficient pedaling when it's needed most.
- SHIMANO SHADOW RD+Ā chain stabilizing system (clutch):
- keeps chain taut, reducing both noise and damage to chainstay
- is lighter and more efficient than roller chain-guide systems
- toggles on and off for easier maintenance.
- Single screw clutch tension adjuster makes fine tuning quick and easy.
- Reduced chain tension in low gear chainĀ position (on large sprocket) ensures a silent drivetrain in all gears.
- Hidden away, low-profile design helps avoid derailleur damage.
- Features a larger, 13T pulley with a new bumper to help further dampen any chain sound.
- Bumper structure at rear derailleur pulley cage reduces impact shock by absorbing chain impact on aggressive terrain.
