Why not adjust the saddle??(4 posts)

Why not adjust the saddle??Tim
Oct 24, 2001 8:50 PM
I'm in the same situation as the 5'8'' guy witht the 56cm Trek. I put on a smaller stem AND adjusted the seat forward, and am not in a more comfortable, albeit not totally aero position. So what is the problem w/ adjusting the saddle forward?

There are two adjustments for the saddle. One is for the height setting and can be determined by various methods. The second is for the knee over pedal position (KNOP). The preferred starting position is the neutral position. If your saddle is adjusted too far forward it will put you in a forward KNOP. It could cause knee injury. If your top tube is too long or too short you should adjust by going to a different length stem.
There is a lot of debate on KNOP being that your position changes depending where you are positioned on your saddle.
I would think that you would want to start with a neutral KNOP and try if out for a couple of weeks, at least, then adjust from there.
For what it's worth my old knees are going on six decades and I've never experienced problems. Perhaps because I dialed in my KNOP (I prefer a 1cm back) or maybe just because of genetics.
If you need info on setting your KNOP let me know and I'll provide you will a couple of website. Sorry it's late and the old brain cells are tired...

The problem lies with sizing riders/bikes according to your inseam length and some arbitrary formula, when a better method for recreational riders would be to size according to the top tube length and the rider's style and flexibility. There is no disputing that riders achieve a longer effective pedal stroke when set back from the BB - hence the preference for not having the seat too far forward - and that bikes handle best when the rider's hands can get over the front axle when in the drops - hence the 'right' stem length and top tube, but after that its all about comfort. What helps it to have the best bike if it hurts you after 50 miles. Race performance over any meaningful distance is as much about comfort as anything else, fitness included. The older/less flexible you are, the more important set-up becomes, especially 'reach'. The pro's you see riding in the drops spend countless hours practising that aero position. Recreational riders/racers don't have that need. Then its better to have a more upright position with less 'reach' and 'drop'.

You don't say how long you've been riding or what part of you is uncomfortable. It sounds as though you're pretty new to road riding and are trying to create a comfortable riding position. It's better in the long haul to get comfortable in a good riding position. Leave the shorter stem on the bike and get the seat back to the KOPS spot. Allow your body time to adjust to this new posture; most likely it will and make very small adjustments if needed.
