In the not-dead-yet category…
Having read the comments about road tyres (tubed) on Crests I thought I’d give it a go with my usual winter road tyres: Michelin Krylion 25mm at 80 psi.
They went on easier than I thought they might, and worked fine on the commute, so I left them on & have now done 4 x 200k audaxes and months of commuting. One puncture and the tyre came off fine.
Crests are 60g lighter than my former default road choice Open Pros, and my usual tyres come up loads wider on a wide rim…I’m sold. 🙂
(I’ve also run 35mm SB8s on Crests tubeless at sub-40 spi without issue).
