    I've never met any cyclist who would seriously consider riding a fixed 53x12.

    Exactly and yet most testers will be using a gear of that size when riding a flat course hence the comment. A lot of time triallists would struggle to maintain the cadence required to use a sensible fixed gear ratio as the preference seems to be for mashing big gears.

    What sort of gear would Obree and Boardman have used when they rode fixed on the road?

    Would you class those two as 'most testers'?

    Obviously not. I was just interested to know.

    Why do time trial bikes for flat time trial courses have gears?

    As far as I see it, the only real purpose for gears is climbing or on a course where there is a lot of slowing down and speeding up, which seems to be unusual to say the least. I cannot see the advantage of having gears on a course that is basically flat. Can someone enlighten me?

    To catch hold of, and bite chunks out of their food but I don't think that's why TT bikes have gears.
  • The question was meant to be as stupid as the one about TT bikes having gears. TT bikes have gears to facilitate a more efficient cadence while also taking into account variable conditions.
