I bought an extra tube for my Mu P8 as i am going on a 5 day trip to Montreal next week and was wondering if the Schwalbe Marathon Racer 1.50" is ok with a standard 20" 1.75 BMX tube ? the tube instructions say it fits 1.50" - 1.95" tires and the guy at shop was clueless about folders and said it should be ok for the Marathon Racer but i am still not quite sure about the tube. Silly question huh ? :notamused:
Any comments ?
