Ride Quality

  • Titanium has a faster return to its original position, but similar dampening properties to steel. The result is a more efficient ride that is still extremely comfortable

  • 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

  • CHUMBA Oversized Select Tubing throughout yield large tube miters for strength and a low frame weight of only 4 lbs

Build Quality

  • Made in USA quality

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

  • Oversized Aerospace Titanium 3/2.5 Grade Tubing 6/4 on the yoke and dropouts w/ Paragon Sliding Inserts

  • Clean thoughtful cable routing
