XG-899 E-BLOCK™ CASSETTE

E-BLOCK™ shifting technology is a fundamental redevelopment of external drivetrain shifting. On the E-BLOCK™ cassette, the chain has a defined link position on each cog. Cog architecture has been engineered to work with both inner and outer links of the chain, which allows extremely refined shifting for both inboard and outboard shifts. The result is precise and robust shifting performance in any situation, even with full motor support.

  • 11-48t, 8-speed cassette machined from case-hardened tool steel
  • Ideal mid-ship motor gear range
  • Increased chain wrap on climbing cogs
  • Symmetric shifting geometry allows fast, precise gear shifts
  • Optimal inboard and outboard shifting performance
  • The big steps between cassette cogs is a completely new cassette technology engineered specifically for the demands of E-MTB
  • Non XD™ driver body compatible

SRAM EX1 | MTB-Mag.com | April 2016

"The use of eight gears was ideal: we did not feel the need for more."

"This is a big change compared to our previous experiences."

"EX1 will definitely improve the shifting experience on pedal assist bikes."
