Designed to pair with the ROTOR 1x13 system, this 13-speed cassette has range options for anything from crit racing to spinning up mountains on weeks-long adventure rides. We use a two-piece steel and aluminum construction to keep weight down without sacrificing durability. It is truly a beautiful piece of machining.
Gear range and sprocket sequencing were developed by analyzing pro rider power meter data from over 1 Million KM, 40,380 hours of riding, 2,400 days of competition and 12 million meters climbed. The first seven sprockets have a closer progressive sequence and the six larger sprockets offer greater increments.
