Reviews & Ratings
The XMCS 2026 Gravel Bike is an upcoming aero gravel frame designed by Peter, featuring 57mm tire clearance front and rear without compromising geometry. It has a T47 85.5mm bottom bracket, proprietary aero seatpost, in-frame storage, UDH compatibility, and mounting points on the top tube and down tube. The frame weight is approximately 1035g (size M) with a 450g fork. It supports both 1X and 2X drivetrains, though front derailleur mount may be tight with large tires. Two handlebar options are available: GR: AERO and GR: RISE (with 25mm extra stack). The frame is priced at USD 1490, with package deals including handlebars and wheelsets. Delivery is expected from May to August 2026, starting with size M. The design focuses on aero performance and wide tire clearance for racing, rather than adventure or touring features. The first frame has been produced and is undergoing rigorous testing; it will be displayed at Eurobike in June 2026. Some concerns exist regarding potential chainring size limitation (max 42t unconfirmed) and lack of fork mounting points.
