I bought Schwalbe pro One Microskin tubeless tyres based on on-line recommendations. There is no doubting that they are light and fast. My experience of installing them is that whilst they are no more difficult than a conventional clincher tyre, it will probably be better to add the puncture repair rubber solution through the valve (i.e. removing the valve core) rather than pouring it in before final tyre installation. This is because the tyre walls are quite thin, so they flatten on the ground as you heave the last edge of the tyre over the rim. This lets the fluid flood out onto the floor, so you don't know how much remains. The ride is comfortable, because you can get away with relatively low pressures (80psi for a body weight of 70Kg). However they are not ideal for lanes around areas with a high flint content in the soil, like the Surrey Hills. Here after just 50 miles I'd had one puncture (which self-repaired to a ride-home-able low pressure) and several surface slits of several mm length. I'm disappointed given the cost and can't recommend them for roads across similar geology. However if I were racing on semi-perfect, smooth roads - then they are probably ideal. Sadly that's not where I live.
Schwalbe Pro One are great tyres, now starting to run tubeless - all good so far. Mantel outshone all other suppliers for price and especially in-stock delivery.
