Avertised at around 350g for a 29:er tyre got my attention.

Does anyone have experience using these at races? Will they work as a rear tyre at e.g. Ourimbah (assuming it is reasonably dry) without flats? Can they be setup as tubless or will it require massive amounts of sealant?

My concern is ripping a sidewall and the race is over but the weight is very attractive so if they do work then it could be the way to go.

Anyone who's been through this and can offer their experience?

Cheers!
