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.
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.
On a frame the highest concentration of stress is at the junctions between the headtube/toptube and headtube/downtube. To handle the pressures of modern riding, the required strength is achieved using a combination of butted tubing and external gussets.
