Features on his frame include: Top and DownTube Subrosa gussets, hydro-formed downtube, CNC shaped BB shell, built in seat post clamp, removable brake mounts, laser cut seat stay bridge, tapered seat stays and ovalized chain stays and CNC Dropouts with weight relief on the inside.

What do some of these features mean to you? Well the hydro-formed downtube shape is very subtle. The slightly flattens and widens at the BB junction to provide a wider welding surface area for strength and to reduce side to side flex of the frame.

The ovalised chain stays allows more clearance for wider tires (2.50 will fit slammed) and it also allows room to run hubs guards on both sides.
