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.

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.
