How to get your seat height right

Setting the correct seat height would seem to be such a fundamental part of cycling that you would have thought the boffins had agreed long ago on the best method. But you’d be wrong. One thing all the experts agree on however is that if you get the height wrong, the effects can be catastrophic. A study suggests that setting the height too low can decrease time to exhaustion by as much as 12 per cent. Consequently cyclists with limited time on their hands might actually get more out of a shorter session by lowering their seats to a sub-optimal level so as to make it harder. It’s an interesting theory, but even knowing how to get it wrong presupposes that you know how to This is the one every bike shop owner or gym assistant will tell you whenever you clamber onto the saddle. You place the heel of your shoe on the pedal and set the saddle height so your leg is straight at the bottom of the pedal cycle with the pelvis remaining in a horizontal position. Despite this commonly heard method, there is virtually no scientific evidence to support it and it often leads to the saddle height being adjusted too low. Professor Will Pelever of Mississippi University for Women has written several papers comparing methods for finding the best seat height and says, “The main problem is that this method does not take into account individual variations in femur, tibia and foot length.” The 109% method A more robust method was developed by Hamley & Thomas in a 1967 paper. They experimented with different saddle heights and found that the ideal was achieved when the saddle was positioned at 109% of your inseam length when measuring from the pedal axle to the top of the seat height. Your inseam measurement is basically the length from your crotch to the floor. To calculate this, face a wall and put a thick-ish book between your legs as if it were a saddle. Ensuring that you are standing straight with your heels on the floor, mark a line along the top of the book edge touching the wall. The distance from the floor to the height of the mark is your inseam measurement. It’s best to measure it several times and take an average. This has proved an extremely popular method and is recommended by many top-level coaches. Yet a recent study by Professor Pelever found that it was inferior to the Holmes method (see below) both in terms of power output and economy.  (Aug 22, 2013 | post #1)
