Shimano gives the SLX RD-M7100-SGS a low profile shape that tucks closer to the bike on tight singletrack. The HYPERGLIDE+ drivetrain system keeps shifting smooth in both directions, while the SHADOW RD+ clutch helps control chain movement across aggressive terrain with a larger 13T pulley and impact absorbing bumper structure.
Key Features
- Pulley Size: 13T
- Drivetrain System: HYPERGLIDE+ supports smooth, quick, quiet shifting in both directions
- Chain Stabilization: SHIMANO SHADOW RD+ clutch system keeps chain tension consistent and reduces chainstay noise
- Low Profile Shape: Rear derailleur sits closer to the bike to help reduce impact exposure on technical trails
- Impact Damping: Rear derailleur pulley cage bumper structure absorbs chain impact on rough terrain
