A RELATIONSHIP YOU CAN TRUST. Two years ago, our aluminum classic received a new frame. The robust yet lightweight bike is suitable for both trails and everyday use. A longer top tube and a flatter head angle increase downhill stability. The Boost rear end, including the thru-axle, as well as the tapered seat tube in the bottom bracket area provide increased stiffness, while the slim 27.2mm seat post adds comfort. The triple-conified aluminum frame is optimized for the use of single drivetrains, allowing for further weight savings and increased stiffness. The ULTRA offers mounting options for side stands, fenders, and racks, making it your reliable partner that you can trust day after day.
