A motor-specific chain guide system for Bosch SX (and compatible Bosch CX Gen4) eMTBs, protecting the compact motor from trail strikes while keeping the chain on a 32T ring.

Highlights

  • 104BCD spider, composite bashguard and 32T chainring in one kit
  • Rugged composite bashguard shields the motor from impacts
  • Forged-CNC spider with a 7075 aluminium Helix narrow-wide chainring
  • Custom spacers let the spider and chainring be run without the bashguard

Compatibility & fit

Fits Bosch SX motors and, per e*thirteen, is also compatible with Bosch CX Gen4. 55mm chainline, 15.5mm offset. e*thirteen guarantees this fit only with e*thirteen cranks; check compatibility before fitting to a non-e*thirteen crank.
