Composite 29er FS Race Frame - Work-in-progress
Still a work-in-progress, this frame is a composite moulded structure utilising live chainstays for vertical compliance but high lateral stiffness, an integrated seatpost and carbon fibre suspension link. Moulds have been machined and are being prepared ready for initial moulding trials.

production process
This frame is to be made using machined epoxy tooling board moulds and a custom formed silicon bladder over a cast foam core (which is later removed). Chainstays are moulded with the mainframe. The seat stays are moulded separately and joined to the chainstays by overmoulding the form of the carbon dropouts (compression moulding).
This frame is designed for a 2x10 Shimano drivetrain.
