And if so, any downside to using them ?
Thinking of going tubeless on the mtb ( apparently, like garlic bread, it's the future, and possibly the only way I could ride up those confounded cobbled hills of Jack's ),
Just enquiringly, I doubt the reduction in rolling mass would bother me, so we can discount that.
The rims are tubeless ready, so it's just a case of new valves and the sealant.
