The idea is to run them on my (disc brake) MTB all year, and then for maybe up to three special trips a year use them on the (650b converted) roadbike with rim brakes and 32mm tyres. There are a few gravel projects I'm looking at, including overseas

Looking to try a Notubes Crest, because it's so light. Will it shred to pieces with a rim brake 5 days a year?
