inner tube rolling resistance
During a flat tire instance, I noticed that my Conti 5000 (25C) wear indicators were getting low. I had 2 brand new tires (same as before) and 2 brand new tubes put on. The tubes were RavX butyl rubber. Don't know if my mind was playing games with me, but it seemed that the rolling resistance was more noticeable on our next ride. I know that tires have various types of rolling resistance, but do tubes also? What inner tubes do you use on your tandem? I don't plan to use latex tubes, so we are talking rubber here.
