how old are your Nevegals?...I just replaced my Kenda Karma Pro Stickees with Nevegals and had an indredible time trying to get them on the rims...its like they were .25" too small
it finally took two of us at the LBS to pry them on from both sides, and now I'm concerned that I'll not be able to get them off if I have a problem on the trails
BTW...The Karma Pro beats the Nevegal in every category...rolls smoother, corners better, grips better on the climbs
no more nevegals for me when these wear out
