Yup, over a year now for me and no problems at all. Only 1 flat from a 1/2" cut from broken glass that would have sliced a tube as well. The same riding areas used to flat my tubes about once a week. I'm 185 lbs and no dented rims, running pressures as low as 30 psi. Maybe it hasn't worked well for everyone, but I'm sold on it and I'll never go back to tubes. They are too much work.Capt_phun said:I put Stan's up to the test in rocky, rooty West Virginia. Rode Continenal Escape supersonics (the light version) with two scoops of stans in each rim on Crossmax SL wheelset and not one problem. Help up nice at 33psi, no rips, burps, leaks on the trail. People running tubes had 9 flats I think the count was over 5 days. I'm impressed.
