ADVENT X Ver.2 Rear Derailleur

How do you improve on a classic? ADVENT X Ver.2 is the same great derailleur you know and love, but with an all new cage design that improves performance under the hardest riding. The new cage offers better chain wrap around cassette cogs. Shifting speed and chain retention both improve. And more tooth engagement on the cassette means longer cassette life, especially on the small cogs. The new linkage mechanics reduces shifting effort, making shifts more responsive and feels better. If you liked the original ADVENT X, you will also love the Ver.2.
