Constructed of rust-free aluminum alloy in an alternating wide/narrow tooth configuration to both reduce weight and improve chain retention. Suitable for any bike type.
Available in multiple teeth choices (32T/34T/36T/38T) and color choices (black/green/red/blue).
Crank length: 104 BCD
Weight: 40g (32T), 51g (34T), 63g (36T), 83g (38T)
