Hi, i am a bad T/T MAN and was wondering if using 20mm instead of 23mm tyres would make any difference - i am 6 foot 5 and 13 stone.

    It would make a difference, you'd probably be slower! 20mm tyres are not going to gain you valuable seconds, the difference in rolling resistance is probably microscopic. Stick with 23mm or even 25mm and pump 'em up hard :wink:
    What do I ride? Now that's an Enigma!
