eThirteen Helix Race cassette 12-speed intergalactic
The eThirteen Helix Race 12-speed cassette is available in two versions. The 13-52Z cassette shines with fine gradation in the upper sprocket range and makes it easier to find the optimal cadence in alpine terrain for maximum efficiency.

Athletes who like to race on the flat or downhill as well as feather-light climbers will get their money's worth. The 13-52T cassette has special reinforcements for e-bike use.
