This DD version of the Aggressor tire has been the most difficult to mount and I have mounted many tires over 35 years of riding. These tires are compatible with my Bontrager rims but are hard to mount due to the rim tape. Anyway, after hours of wrestling I got them on the rim only to have them peel off after 6 miles of riding. Fortunately I did`t wreck or damage my carbon rims. The bead must have been slightly damaged during install. Trying to mount them again they would simply pop off the rim during inflation. Now I have a new tire that I cannot use on my Trek Fuel EX and is likely unusable on other rims.
