Schwalbe's latest addition to the Pro One family comes in the form of the Pro One Aero. With the Pro One Tyre, the goal was to develop a fast, lightweight and safe tyre which at the same time offers maximum flexibility. It's a tyre that quickly and accurately responds to a cyclist's riding style and always provides sensitive feedback. All this means the rider gets less fatigued and can achieve greater performance. The Pro One Aero adds so much more by guaranteeing 20% less drag than the Pro One TT, a higher puncture resistance with an improved raceguard material and has been optimsied in the wind tunnel with aerodynamics at it's heart.The Pro One Aero does not sacrifice aerodynamics for performance. The front and rear of these tyres have been designed differently, the front focuses on aerodynamics whilst the rear focuses on having a lower rolling resistance and high puncture protection.The turn-up construction integrates Tubeless Easy Technology in the most progressive way possible. Two carcass layers underneath the tread render the tyre smooth, comfortable and puncture-resistant, while three lateral carcass layers ensure high cut resistance.Raceguard: 2 layers of crossply Nylon fabric on a high-grade 67 EPI carcass. For proven protection of light tyres.**Specifications*** Compound: ADDIX Race* Folding: Yes* Compatibility: Not E-bike ready* Pressure: Front - 5.0 to 7.5 bar, Rear - 4.0 to 6.5 bar* Max load: 70kg* Weight: Front - 235g, Rear - 270g**ETRTO*** SCR3880R: 28-622* SCR3880F: 28-622
