A RELATIONSHIP YOU CAN TRUST. Last year, our aluminum classic received a new frame. This robust yet lightweight bike is suitable for both trails and everyday use. A longer top tube and a flatter head angle improve descending stability. The Boost rear end, including thru-axle, and the tapered seat tube at the bottom bracket provide increased stiffness, while the slim 27.2mm seat post offers comfort. The threefold conical aluminum frame is optimized for the use of single drivetrains, resulting in reduced weight and increased stiffness. The ULTRA offers mounting options for side stands, mudguards, and luggage carriers, and is your reliable partner that you can trust day after day.
