The super short cage version of our popular ADVENT rear derailleur has the same features as its longer cage counterpart, but with a cage short enough to be used on a 20-inch wheel bike. The ratchet clutch system and return spring have been precisely tuned to compensate for the shorter cage and lighter chain, allowing the derailleur to deliver fast and accurate shifting with minimal effort.

• Reliable, easily adjustable, and serviceable ratchet clutch system
• Direct cable entry for smooth and responsive shifting
• Compatible with 9-speed cassettes ranging from 11-34T up to 11-38T
• Only compatible with Advent shifters
