Shifting to 1x10 gears is easier again thanks to the new ERC widening pinion, with which you can climb even the steepest climbs. In addition, the E-13 ensures accurate and fast shifting thanks to the elaborated approaches and the EXA+ material with a hard-anodized surface treatment that extends the life of the pinion.

It is recommended to pair this pinion with M profiled converters for maximum functionality.

Designed for ten speed cassettes with a single derailleur combination.
Use - you remove a 17-tooth pinion from an existing ten-speed cassette that is compatible, which creates space for fitting an ERC pinion behind a pinion with 36 teeth.

Material: EXA+ Aluminum
Thickness: 5 mm
Compatibility: 10 speeds
For size: 42z. Shimano and 42z. Shame
Colors: black, red, blue
Weight: 77 g
