A major incentive for PYGA has been to find ways to manufacture a carbon frame without the waste that traditional techniques incur. BST has a proprietary process that uses no air bags, polystyrene cores or polyurethane formers that would have to be disposed of. Instead, they utilise re-usable internal formers that are the precise shape of the inside form enabling near perfect compaction throughout the frame time after time, something that is not easily possible with current production methods.
BST have also developed a resin system specific to their wheel production, this pre-preg resin has incredible impact resistance as would be the expected requirement of a wheel that needs to remain safe at speeds in excess of 400km/hr.
Duncan McCann, PYGA partner commented: “The lack of waste product we have achieved from the manufacture of MoBu personally excites me and aligns with our mission to minimise the impact we make on the environment, significantly reducing our carbon footprint”.
The MoBu has uniquely engineered flex, which translates into better cornering traction and forgiveness and overall ride quality. A result of the initial testing and pro-rider feedback.
The frame holds two full size water bottles, has a lower shock mounted flip-chip and will run a 185mm x 52.5mm length trunnion Rockshox Ultimate on the trail version and a 185mm x 47.5mm length SIDLux on the XC/marathon setup.
The aluminium rocker link is highly CNC machined and intentionally made from 7075 alloy instead of carbon. The weight difference would be negligible and PYGA’s philosophy is to utilise carbon wisely. It features a hirth-joint axle which provides exceptional torsional stiffness to the bridgeless rocker.
Cables are internally managed with anti-vibration foam tubes with a lower cable port for ease of installation. Rubber grommets seal off all entry and exit ports.
Up front, the fork is connected to an offset tapered headset cup providing 10mm of reach and toptube adjustment enabling the fine tuning required by many riders.
The one-piece swing-arm is internally mounted to the front triangle providing a smooth look to the BB area which utilizes a threaded 73mm BB standard.
In addition to 148mm boost, the drive-side of the rear end has been offset by 2.5mm which may not sound like much but is enough to improve the chain-line and rear wheel stiffness while allowing the use of a standard wheel in emergencies.
