• Butted Seat Tube & Miter Cut Top Tube:
  The seat tube is where all three triangles of the frame meet and it is crucial to keep this tube strong.
• Tapered Chain & Seat Stays:
  Both chain and seat stays taper to provide a refined and clean look to the frame while still providing strength. The are both angled on the inside for improved chain clearance and weight savings.
• Post Weld Machining:
  The Mid BB and Headtube is machined to its absolute minimum without sacrificing strength or durability. The machining happens after welding for a precision bearing fit.
• Integrated Head Tube:
  The integrated headtube is machined to its absolute minimum without sacrificing strength and durability. The machining happens after welding for a precision bearing fit.

  Hollow 8mm wide dropouts are as light as a solid 5mm dropout, but over twice as strong. There is a small internal chain tensioner to hold the wheel in place as well as simplify wheel removal.

  Refined removable brake mounts and cable channel improvements that provides benefits with or without a brake setup.
