Specialized Roubaix Pro tyre

The Specialized Roubaix Pro is an endurance road tyre that's well suited for smooth and rough roads alike. That's because it's fast like any competitive road tyre, with a Black Belt technology for puncture protection. Meanwhile, the casing smooths your ride and keeps you fresh, while the tread handles responsively over mixed terrain. It also features a slick center tread for low rolling resistance and shoulder sipes for increased surface adaption and grip.


Features

  • Compound: Gripton.
  • Flat Protection: Black Belt.


Technologies

Black Belt
An extra layer of uniquely-crafted fabric with highly resistant properties sits between the casing and the tyre to reduce the risk of punctures. The technology is higly recommended to be applied on the tyres intended for use in intense conditions with a high puncture risk.

Gripton compound
The Gripton compound uses 'mostly synthetic rubber reinforced with silicon dioxide', which reduces the amount of energy lost through hysteresis. This basically means less deformation, less heat build-up, and a more efficient tyre with improved rolling resistance when compared to natural rubber. The Gripton compound is soft, allowing it to adapt and conform to rough surfaces. It has a durometer of 56 A, making it much softer than other tyres, meaning the tyre not only conforms to the surface it is rolling over, but also filters vibration, which produces a smoother ride.

Note: Roubaix tyres have a special "23/25-622" casing format, what exactly means 23 mm tread on a 25 mm casing and "25/28-622" casing format, means 25 mm tread on a 28 mm casing. Larger volume, but the tread that is in contact with the road is reduced to minimise rolling resistance.
