These are just a few of the minor problems that could occur while riding your bike. Such adjustments which I have found to make the biggest difference to a cyclist’s performance is the cleat position under your shoe, the height and forward position of your seat, your crank length, the seat and top tube length and finally the stem length.
Consult a bike specialist if you wish to be sure that you are riding in the
most econmical position and ask them about other bike upgrades which could
also improve performance. Most bike specialist around charge around $30 -$40
(Australian). Otherwise if you feel confident with the mechanics of your own
bike, you could check out a site on the web set up by
Quintana Roo, that tells you exactly how to set up your bike. You will be amazed with the difference that a few alterations on your bike can do to your performance on the road.
