Super easy to get on my Cannondale Hollowgram wheels. The stock tires (Victeria Rubino's) were a major PITA to get on and off the wheel. These are a breeze in comparison. Ride quality is great too - subtle and smooth. Very happy with my purchase!
Put about 200 miles on my Agilests now and am very satisfied with how they roll. Light weight, soft and supple feel, and were very easy to get on my Spingery ZLite wheels. I can feel the difference on descents - the bike just goes faster now, without extra effort.
Note to self - might get the duro versions later on, as the roads I ride on are riddled with glass and sharp objects.
