Ride Quality

  • A balanced BB drop: Positioned to bring out the rest of the geometry and give clearance to pedal through technical rock gardens, climb with power and stay playful on the trail.

  • Supple where is counts: S-Bend seatstays, sloping top tube and bent down tube. These choices help the bike track in the rough and dampen trail vibrations.

  • Stiff chainstays and strong CHUMBA Oversized Select Double Butted Tubing throughout yield large tube miters for strength and a low frame weight of only 5 lbs.

Build Quality

  • Made in house/USA quality

  • Flawless frame miters, all tubes are heat sunk and argon purged when welded to prevent distortion and material thinning.

  • CHUMBA Oversized Select Double Butted Tubing and PMW stainless steel sliding dropouts, mean this bike will exceed your expectations and provide years of reliable trail service.

  • Clean thoughtful cable routing
