Description
  • Work flawlessly with Shimano, SRAM, and TRP 12sp shifters, regardless of different cog spacing and chain behavior
  • Improved reliability of a steel and aluminum assembly
  • The Intergalactic PVD finishing is twice as durable as anodized models
  • Designed for steep terrain where climbing time and shift frequency is high and descents are gravity driven, allowing optimized cadence and torque for more efficiency during climbs with smoother shifts under load for both analog and ebikes
  • 13-52t range compliments speed limited e-bikes where the highest gear, paired with a 32t chainring and 85rpm cadence, delivers speeds around 20mph, where e-bike motors cut off
  • Special note for Hope hub owners: Hope XD drivers do not adhere to SRAM XD specification and require an additional shim. Shims can be acquired from E*Thirteen
