Real racers always want to improve by getting better and faster. Result: Schwalbe radically revised Racing Ralph for the second time - with PaceStar Compound and a completely modified profile. Also, the hard numbers show how ambitious they were:
Carcass: 127 EPI
Weight: -30 g
Rolling resistance: -20%
In addition, the modified profile and PaceStar compound provide even better control.
