I ordered one of these new Foss Tubes from RBW (forgot to order the proprietary patces, dang) It arrived with a set of warnings, and a role of two sided tape that looks like maybe a new fangled rim tape, but no instructions. It is explicit about only using this tube with the stated tire size.
I ordered the medium - 34-44 for use with a Jack Brown, but what arrived is huge and labeled 1.95 (50) - 2.25 (57). Should I return this tube or try to use it?
Assuming the inclosed tape is a new kind of rim tape, do I replace the current tape or install it over the existing tape?
Does anyone have personal experience with these tubes and what can they share?
Thanks,
michael
