TUBELESS EASY HIGH-END TIME TRIAL AND TRIATHLON TIRE.
Uncompromisingly for competition use. TT stands for speed, lowest rolling resistance and minimum weight. The riding characteristics are nevertheless inimitably good.

• Super Race carcass (Souplesse construction)
• Addix Race Compound

In order to minimize weight and reduce rolling resistance, the Pro One TT runs without a puncture guard. Therefore, it must be run with sealant for added puncture protection.

TT stands for Time Trial.

Instructions for the first assembly: Schwalbe Pro One and Schwalbe Pro One TT Tubeless Easy tires must be used with Doc Blue tire sealant. At least 30 ml, preferably 60 ml per tire. The tire must be run for at least 25 km directly after the sealent is added. If the instructions for the first assembly are ignored, the sealing of the tire cannot be guaranteed.
