I can't believe how my old bike rides with these tires . It has totally changed how it rides . It seem to have a better roll with less drag . I ride with less effort and very smooth . They also look great . I ride mostly on asphalt and rail trails . I couldn't be more pleased . I used some talc powder on my new tubes . The tires were a tad tight going on but I didn't need tire tools . Fast free shipping .
Game changer for my old Trek 820
