  • Fitted a 25mm Conti Ultrasport II to the front of the bike. Realised the tyre arrow is pointing the wrong direction. Could flip the wheel and QR.

    It doesn't matter, does it?


  • If tyre markings looks like the right one it could be faster in reverse... :)

    However an interesting discovery was made with the GP tyres. These tyres have a directional tread pattern with some directional channeling. Therefore it was decided to test this tyre in both rotational directions (Dir-1 & Dir-2 in the graphs) to see any influence on the results, in particular in the separation point. Interestingly the reverse direction (Dir-1) offered the best aerodynamic performance.
