Nice Andrew, nice! I've been on Procore for a few weeks now on my heavy duty wheels. Magic Mary front, Hans Dampf rear (for now-cleaning out storage). Tire feel at the lower pressures for normal Snakeskin tires is pretty unreal. I would never have been able to run lower pressures (22 front, 24 rear) on narrow 23mm rims without the tires folding or burping. They add about as much weight as an average tube (maybe a bit more), but honestly its tough to tell for just all around riding. If one were to drop major cabbage on carbon rims I think it's a wise investment even just for the rim protection. A 1500 gram set of carbon hoops with Procore still ends up to be a fairly decent weight, awesome performing wheelset. Oh, and Ken burped his 27+ at the fiver, and Wade…and….;-)
Tire swapping can be a bit messy, but once you get a system, it is pretty quick.
Next up will be trying Maxis tires with the setup
