The BSD Freedom Frame is the signature frame of BSD team rider, Kris Kyle. BSD took the already great design of of Kyle's last frame and improved on it with and investment cast wis h bone to make the rear end stiffer and stronger to resist bending under heavy abuse. Kriss Kyle signature Sanko Japanese seamless 4130 CrMo triple butted tubing Invest Cast Seat Clamp: 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. Invest Cast Dropouts: 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. Invest Cast Wishbone: 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.
