MINI CLUSTER™ The MINI CLUSTER™ hybrid cassette construction combines three small cogs that are CNC-machined out of a single block of billet steel with an additional eight cogs that are individually pinned together. The result: a cassette that’s light, durable & equipped with a 10-42 gear range that’s a perfect fit for any ride. X-Glide™ Imagine being able to shift smoothly at any time, no matter what.
