Performance

Extended development range

With its 10-52 tooth range, the cassette offers a 520% range, allowing it to handle both steep climbs and fast sections.

Efficient transmission

The cassette design allows more time to be spent on the upper part of the cassette, where power transfer can be more efficient depending on the configuration used.

Sharp speed changes

The open architecture and X-Dome design contribute to precise gear changes, even in demanding conditions.

Reduction of mud accumulation

The open design helps to shed mud, which promotes cleaner operation and can help preserve the transmission.

Compatible with larger trays

The 10-52 tooth range allows riders to consider larger chainrings to increase top speed, while maintaining good climbing ability.
