The CST Surge XC brings stability and grip to 20-inch fat e-bikes. A large, symmetrical central tread improves riding stability and durability, while criss-cross grooves add extra grip across different terrain and help clear water and mud.

Highlights

  • Large symmetrical centre tread for stability
  • Criss-cross grooves for grip and drainage
  • DC2 Enduro compound with TU2
  • Defender EPS puncture protection
  • 40 TPI fat-tyre casing with wire bead
  • E-bike rated to 25 km/h

On road and off

CST's DC2 Enduro compound balances rolling resistance on the road with grip off it, and works especially well on dry mixed terrain. The special 40 TPI fat-tyre casing is designed to ride more comfortably than conventional tyres.
