The name alone indicates how significant this new tire is for Schwalbe. It is the fastest and most reliable competition tire Schwalbe has ever made. It is manufactured in a separate facility built exclusively for the production of this new top-class tire. To achieve extremely low rolling resistance, a completely new compound, the OneStar Triple Compound was developed. The new triple compound is based on special polymers that have only recently become available. As a result Schwalbe has achieved a great improvement in the familiar trade-off between rolling resistance, wet grip and durability. The One Star Triple Compound is not only faster; it also delivers the grip Schwalbe's triple compound is know for and is more cut resistant than previous compounds.
I've tried a few different road tubeless set ups, and these are probably the best on the market. Roll well and more durable than Hutchinson Fusions. However, I wouldn't say the performance is better than the best non-tubeless I've used (Conti GP4000s, Vittoria Open Pave's - both with latex tubes) but with a little sealant these are less likely to leave you having to fix a flat on the side of the road. The only real downside to road tubeless is the mess of sealant residue that has to be cleaned when you're switching tires.
