|I recently had a bike fitting done with my existing bike. The fitter moved my seat back quite a bit in order to get my knee cap plumb with the pedal, when the pedal was in the horizontal position. He said my previous position was not allowing the lower quads to develop. I've ridden maybe 100 miles with the new position and have now developed a significant pain on the outside of my right knee. It starts to hurt ~15 miles into a ride and mostly on the down stroke. Is it possible this pain is due to being further back on the bike, or is it just conicidence?. Am I working my lower quad in a way I wasn't before? and might this qo away as the strength in various muscles evens out? |

|It is entirely possible! Fit is everything, and changing your position on the bike can cause your body to work in a much different way. Whether "it" will go away or not, only time will tell.
In the meantime, stretch, stretch, stretch (only after warming up of course).
Please let us know how it goes.

|here's an article for you on KOPS.
Regarding knee pain--pain is not good. I'd switch back to what feels right to you.

|IMO, your position shouldn't have been changed all at once. If the fore/aft position of the saddle needed a significant shift, you should have made small incremental changes every two weeks or so until you arrive at your goal position. Big and sudden changes in position tend to have negative consequences, but a slow gradual shift in position will allow your body to adapt w/out any or much pain.|

|any significant change in position must be done in 1-2mm increments at a time. Suggest that you move your saddle back to where it was, then move it a couple of mm every week or so. Meanwhile, go easy, ice, and stretch. Knee pain is nothing to fool around with.

|The sports doc suggested that my ITBFS may have been caused by too much setback. I readjusted my saddle to minimize tension on the outside of the knee, which meant down and forward. For god's sake, be careful with your fit - I lost the entire winter. (I did my first two rides of the year this weekend, 45 minutes max, on the fixte. Doc says that shouldn't be a problem.)|

|Now Im not a doctor, nor do I play one on tv, but I do have a great deal of experience in the sports clinics during my high school and collegiate athletic days. However, this sounds very familiar and the lateral aspect of this pain have me suspecting ITBS.
ITBS is found predominantly in runners and sometimes cyclists and is often associated with sudden changes in training such as a sudden increase in distance or intensity, or change in positioning.
As in your case, the pain from ITBS is felt on the lateral aspect of the knee. The pain may also radiate up the lateral aspect of the thigh or around to the front of the knee. The pain is usually made worse by repetitive flexion and extension movements of the knee. Initially, the pain may only be felt during a ride. If training continues, pain may be felt even at rest.
Your relative positioning over the pedal will differ from person to person and this position will vary from person to person depending on such things as femur length and pedaling style, usually ranging from 4 cm in front to 6 cm behind. As indicated, this dramatic change is affecting your pedal stroke, and likely exaggerating the stress placed where stress was not placed before.
Being too far forward can cause other significant problems as well, including patellar tendonitis, tendonosis and also some high-calf injuries. Use these other riders suggestions regarding gradual moves,but comfortable miles with proper knee-to-pedal alignment will definitely have a more positive impact to your training than a major shift in your seat position.
