Nivex 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. At 185 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.

Pro Tip: The Nivex can be retrofitted to existing bikes. Braze on the Nivex derailleur mount and a chain guide large enough for two cables under the bottom bracket (a simple loop of wire will do).
