Schwalbe Pro One TT

Information about the tire width of the new Schwalbe Pro One (model year 2020)

The design dimensions of the Schwalbe Pro One (TLE, Tube Type) and Schwalbe Pro One TT road bike tires are based around a nominal standard rim width of 19C, the standard for modern road bike rims (formerly 15C). This has an effect on the real tire dimensions when mounted and should be taken into account when buying tires in order to ensure trouble-free mounting and best product performance.

Table: Schwalbe Pro One tire width (HS493/493A) with different rim widths.

x = tire/rim combination not recommended

"C": Crotched (rim flank with hook - standard rim)
"TC": Tubeless Crotched (rim flank with hook - tubeless rim)
"TSS": Tubeless Straight Side (rim flank without hook - tubeless rim)

Note: TSS rims may only be combined with TLE/TLR tires (Tubeless Easy/Tubeless Ready). Regardless of whether they are used tubeless or with tube.

The tire width may vary by +/- 1 mm depending on the rim that is used.

All tire dimensions were determined at maximum tire pressure. (Caution: Due to different rim shapes, the maximum allowable air pressure of the rim must be taken into account. If the indicated maximum allowable pressure of the rim is lower than that of the tire, always comply with the maximum pressure of the rim. This can lead to different tire dimensions).
