Obviously not at the same time, that would be weird.
Just interested to hear some real-world experiences beyond the marketing hype.
Currently running tubed 40mm 700c knobblies for my offroad excursions (WTB Nanos)
Thinking of going tubeless, which means new rims, and wondering if I should go 650B at the same time.
For the tracks I ride the Nanos seem adequate in terms of comfort but they're not exactly fun on the tarmac sections. So I was thinking of something like a WTB Byway in 650B for the dry, hardpacked gravel I usually encounter. Faster rolling for tarmac, with enough tread to handle the gravel sections. I'm not about to go lobbing my tourer down singletrack so I don't need anything too extreme. I ride the Nanos at around 60psi (with tubes) and I guess I could get away with the Byways way lower than that if running tubeless?
Am I really going to notice a world of difference between 650B & 700C? And if so, is that going to be more down to running lower pressures because I've gone tubeless?
