Subject: RE: seat height Sit on your bike while leaning against a wall, or door jamb, or in a trainer Get your pedals in the 12:00 and 6:00 positions that's straight up and down look down at your leg in the six o'clock position, Your knee should be almost, but not quite straight Personally I reccommend using the above time-honored method mixed with real-world experience (in other words, do the rough adjustments as above, then take the bike out for a short ride in a quiet area, and take a wrench and a bit of tape with you) the tape is so that you can mark your previous adjustments without having to scratch your seatpost |
