Hello. I have a half IM coming up and want to carry a spare tubular in the chance I might flat out. I've purchased a stretched tubular which I will carry. I would like to pre glue it so in the chance there is a problem I can rip off and pop on and go. Anyone have any suggestions for preglueing? is it a good idea? Once I put a bead of glue on the tire can the tire be folded up on itself for strapping to my rear bottle cage? Any tips or tricks would be appreciated. Thanks!
