⚡ At a Glance
  • Shifting Performance: Smooth and precise engagement thanks to Double X-Bridge outer plate geometry
  • Best for: Riders and workshops using Shimano, Campagnolo or SRAM 11-speed drivetrains
  • Not ideal for: Drivetrains that are not 11-speed

Compatible with Shimano, Campagnolo and SRAM 11-speed derailleur systems. Non-directional design, asymmetrical chamfering and Double X-Bridge geometry combine for lightweight, quieter shifting.


Quieter, faster gear changes, with Double X-Bridge outer plate

Double X-Bridge outer plate uses precisely articulated angles to guide the chain onto cogs, encouraging quicker engagement and smoother transitions between gears. Description notes that the geometry reduces interference for cleaner shifts.

More confident shifts under load and less chain noise on every change. Particularly useful during fast cadence changes and tight gear jumps.

Broad drivetrain compatibility, with non-directional design

Non-directional assembly means the chain can be fitted either way, allowing compatibility across Shimano, Campagnolo and SRAM 11-speed systems as stated in the product details. No directional alignment simplifies installation.

Simplifies spare management and makes fits quicker for home mechanics and workshop techs. Suitable for swapping between bikes that share 11-speed drivetrains.

Lower rotating mass, with shorter pins and slotted plates

Shorter length pins combined with slotted outer plates and high-grade materials reduce overall weight while maintaining plate strength. The description highlights a focus on lightweight construction.

Improves acceleration feel and keeps drivetrain responsive when accelerating or climbing. Useful for riders who value quick, snappy power delivery.
