Schwalbe Racing Ralph Evolution 27.5*2.25 (650B-57) foldable tire

650 MTB tire. Foldable, Evolution line. Real racers always want to improve by getting better and faster. Result: We radically revised Racing Ralph for the second time - with PaceStar Compound and a completely modified profile. Also the hard numbers show how ambitious we were: RACING. In addition the modified profile and PaceStar compound provide even better control. 29ers have a much larger contact area. For the first time the arrangement and proximity of lugs on the new Racing Ralph have been specially adapted to this greater contact area. It emphasizes rolling resistance and grip. Weight: 530 g. Size: 27.5*2.25 (650B-57), (584-57).
