How do you carry spare tubes with a rear hydration system?
I use a Beaker Concepts H5 on a Cervelo P3. I want to carry 2 tubes during IM races, since I ride 650s with long valves. Up to now, I’ve been folding up the tubes and taping them to the sides of the H5, but sometimes the tube will wear and get a hole. Saddle bags don’t seem to fit well, and I don’t really want to stuff them in a bottle and carry it in the H5 b/c of poor aerodynamics.
Any suggestions? Photos would really help!
