After a full summer of riding Stan's road tubeless system I'm pretty impressed. Rough and chipsealed roads feel almost as smooth as fresh blacktop and the tires are very grippy while cornering. I used to be a 6-7 flats a year type of guy and had to run 120lbs to avoid pinch flats but with this setup flats of any kind have been non-existent. Railroad tracks, huge potholes, no worries. I originally has these setup on a normal rim with spoke holes and I had some trouble sealing the spoke holes with the yellow tape but since I switched over to Ksyriums mid summer the setup had been bullet proof. They lose almost no air between rides. I would recommend this setup for anybody but if you have Ksyriums or a similar sealed rim it can't be beat.
