We've used a new heat treated invest cast wishbone on the Freedom frame. This combined with the new seatstay bridge offers a stronger and stiffer rear end, especially good for sideways landings.
Because the dropout is cast as one piece it's 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;s an integrated chain tensioner bolts inside.
The invest cast seatclamp is built into 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.
