SUPERSCOOP CHAINSTAY
Superscoop chainstay provides more tire clearance for when your wheel is slammed. The tubing is press formed post bending to create extra room where it's needed most without the need for an invest cast yoke.

INVEST CAST DROPOUTS
The dropout is cast as one piece, much stronger than a plate welded to a tube. 7mm thick to provide good support for your axle, and the small shape has been designed for grinding meaning there's no overhang to catch on ledges or rails, also the dropout is heat treated before welding making it extra tough. And finally there are integrated chain tensioner bolts inside.

INTEGRATED SEATCLAMP
The seatclamp is built into the frame so there's no need for a separate clamp. This keeps the frame clean and simple while also allowing the seat to be slammed lower. Also the slot cut beneath the seatclamp gives more clamping power less torque on the bolt.
