Used them for a couple of rides but they’re basically too wide for my old school rims and tyres, I think it affected the shape of the tyre.

Rimpact recommend 20mm internal or bigger rims and 40mm + tyres so should be perfect for most modern gravel wheelsets.

No valves but they’ll work with any valve with ports on the side e.g. Peaty’s etc.
