A RELATIONSHIP YOU CAN TRUST. Last year, 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 single-chainring setups, allowing for further weight savings and increased stiffness. The ULTRA offers mounting options for a side stand, fenders, and a rack, making it your reliable partner that you can trust day after day.
