BST selected ACG's medium temperature moulding prepregs for its autoclave processed carbon composite motorcycle wheels. The BST wheels are reported to result in a typical weight saving of 47% over their conventional aluminium counterparts, with no decrease in strength.

ACG’s high Tg MTM®58B prepreg is used for the rim of the wheel and structural MTM®57 prepreg for the integral spokes.

According to BST, some of the advantages of carbon fibre wheels include:

  • the wheels are lighter and so the bike is lighter, making it easier to handle and reducing rider fatigue;
  • better and lighter handling;
  • faster acceleration;
  • quicker braking; and
  • a beautiful carbon fibre finish in high gloss. 

ACG, part of Umeco Composites Structural Materials (UCSM), a division of Umeco plc, offers a range of prepreg systems for structural and tooling applications.
