The battery is protected from damage, while the wireless setup simplifies installation and reduces maintenance.Dual-spring chain stabilisation with increased chain wrap: Two internal springs deliver 70% more chain tension and a tighter wrap around the cassette. This keeps the chain firmly in place, reduces bounce, and prevents skipping as cogs wear.Crash recovery function: If the derailleur is hit during a ride, it absorbs the impact and returns to position automatically. This helps protect internal parts and preserves shifting accuracy after collisions.Choice of GS and SGS cage lengths: The GS model supports 9 45T cassettes, while the SGS version supports up to 10 51T. Riders can select the best fit for their gearing setup without compromising compatibility or performance.Compact drive GS design with 23mm more clearance: The shorter cage offers improved ground clearance, reducing the chance of strikes on rocks and roots.
