Nivex 9- to 11-Speed Rear Derailleur

The ultimate analog derailleur! We’ve left no stone unturned to optimize the shifting performance of the Nivex derailleur. Desmodromic actuation makes for lightning-fast, consistent shifts across the entire gear range. A clever compensator lever keeps the chain tension constant and prevents chain slap even in small chainring-small cog gear combinations. Precision-machined aluminum pulleys with ball bearings and special tooth profiles for ultra-quiet running even at extreme chain angles. The lower pulley (which is most exposed to spray) has a labyrinth seal to protect the bearings.

At 193 g, the Nivex is lighter than most current derailleurs, yet it’s designed to last, and it’s fully rebuildable. The Nivex derailleur has already proven itself in rugged adventures like Paris-Brest-Paris, the Oregon Outback and Unbound XL.

The 11-speed model comes with a long cage and a large 13-tooth lower pulley to wrap enough chain for modern cassettes and compact cranks. Two shifter cable tensioners are included, making it easy to adjust cable tension and indexing.

Important: The Nivex requires a special braze-on under the chainstay for mounting. It cannot be mounted to derailleur hangers on the frame’s rear dropout.

• Nivex 11-speed derailleur (comes with cable tensioner)
