Interbike 2012: Schwalbe Develops Road Tubeless Ultremo ZX Tire
Schwalbe’s dipping their toes into the Road Tubeless market slowly but surely. The Ultremo ZX Tubeless will be available in limited numbers in February or March, with greater inventory expected by summer.
Weight is about 290g, pricing isn’t final but should be about $100. Only available in 700x23c and only in black. They’ve been testing it under Fabian Cancellara and RadioShack Nissan team riders. Their rep said the benefits they’re seeing comes not just from less flats, but generally less rolling resistance and better traction and comfort by running slightly lower pressures. That said, these are rated for 70-130psi, a pretty high limit for Road Tubeless.
