microSHIFT's 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 cage features a shorter overall length and improved pulley position for better chain wrap, especially in the smaller cogs. With more tooth engagement on the pulleys, shifting speed and chain retention both improve. And more tooth engagement on the cassette means longer cassette life, especially on the small cogs.Backwards compatible with all ADVENT X systemsAluminum cage is designed to provide better chain wrap and retentionUpgraded inner linkage offers easier shifting and less cable tensionEnhanced pulley engagement for faster shiftingAluminum cage is durable with the benefit of weight savingsCompatible with standard 10-speed chainsItem SpecificationsCage LengthMediumChain Wrap Capacity (teeth)37ColorBlackDrivetrain Speeds10Largest Cog48Rear Der/Shifter CompatibilitymicroSHIFT ADVENT XRear Derailleur Mount Type10x1 Standard microSHIFT ADVENT X Ver. 2 Rear Derailleur Rear Derailleur EAN: 4710495438573
