The OSTRO is an aero disc-brake frame which weighs just 780g. Using the very best materials and reaching such a low weight for its class, the OSTRO carries Factor’s VAM designation.
Every element of the OSTRO is optimized for aerodynamics. The mid-chord aero profile tube shapes, the wide stance fork featuring Factor's pioneering Reversing Flow Energizing Channel, and the aero cockpit with fully integrated cabling. The net result is a superlight bike that is ready to blitz as soon as you hop onto the saddle.
The tube profiles are optimized for ride quality and aero to weight balance by truncating the aero section aggressively. As well as being lighter, stiffer and more compliant, these truncated aero sections also reduce drag in crosswinds and better accommodate bottles on the bike. In designing the OSTRO, Factor considered every aspect of the frame and applied the optimum aero profile, with particular regard to the transitions between frame sections like down tube to seat tube, fork and head tube to down tube and to performance across a full range of effective wind angles.
The OSTRO achieves its remarkably smooth ride in three key ways: Tyre clearance, Ultra-thin seatstays, and Carbon fibre layup.
The OSTRO VAM, is undoubtably the best all round lightest performance road bike in the market. We fondly call it The Master of All Trades. Period.
