BSD 2020 GRIME Frameset rāmis, Raw, Denim Cox Signature

INVEST CAST YOKE
The Grime frame has an invest cast chainstay yoke which creates more clearance for the tire for when your wheel is slammed. Also because this part is cast and heat treated it strengthens the rear end of the frame by stiffening it up.
 
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.
 
INVEST CAST SEATCLAMP
The invest cast seatclamp is brazed onto the frame so there's no need for a separate clamp. Also the slot cut beneath the seatclamp gives more clamping power less torque on the bolt. Note the new seatstay bridge too.
