Hi there just a question maybe someone with some experience can help me with. After changing bikes I have a pain in my right side knee on the outside of my knee towrds the back (Approx 90°-130°) around from the front of my knee cap. From what I have been able to read up my position on the bike seems to be correct. My inseam is 875mm and I have set my saddle height at 765mm (Inseam X 0.883) measured from the centre of the bb to the top of my saddle, I have taken off around 10mm for my cleats. My saddle is set so that the front of my knee is inline with the spindle of my pedals.The strange thing is it is only my 1 leg and not both, Im guessing it may be a problem with cleat alignment, but Im not sure which way to change it (toes in or out).
Any help would be greatly appreciated.
Thanks and Regards
David

Lower your saddle 5mm and stretch your hamstrings.

If it's physical (leg lengths differ?), try Lemond's LeWedge or cleat shims from a local ski shop.

if you do like the formulas I thought they included the road (i.e. SPD, Look) cleats in calculations i.e you are not supposed to "take off 10mm" to compensate for cleats.
Having said this - a lot of people do not fit the formulas i.e. they use lower saddle height than formulas suggest.....

Your new bike setup (saddle height, fore/aft postion) could be causing a condition known as ITBF (Illio Tibular Band Friction). Your IT band runs down the outside of your leg and connects to the outside of the lower portion of you knee joint. When you flex your knee, this band moves back across a small protrusion, and creates friction. When you cycle at 90rpm for a few hours, this is a lot of friction!
I could explain more, but instead go here:

I think maybe you should lower your saddle a bit, and maybe adjust your cleat angle, if that has changed too. Also, stretch your IT band daily - it may just be really tight. Google for some good IT band stretches.
If you experience this pain again, R.I.C.E. it! (Rest, Ice, Elevate and take a round of Advil to reduce the inflamation that causes the pain.) Dont Compress it, though.
If you think this might be your problem, let me know. I have fought the ITBF battle and won, although it took ALOT of time and research.

Thanks for all the input guys, its greatly appreciated. Someone else I have spoken to seems to think I may be doing too much too soon having only recently starting cycling again after a 4 year break from the sport. Im going to take my bike down to the LBS and have my position checked out and adjusted if need be. My cleat position hasn't changed so maybe its just saddle height and fore/aft adjustment. If I use the inseam X 0.883 method and then compare it to the put your heels on the pedals and pedal backward method I get 2 totally different seat heights. If i use inseam X 0.883 my saddle height is too high for my heels to even touch the pedals at the bottom of the stroke never mind pedal backwards. I would have to do some serious rocking on the saddle to reach the pedals. I think the best will be to go back to the LBS and let them check everything out.The only other thing I think that may be the cause of it is due to the fact that I changed from a 56cm C-T frame to 58cm C-T and the top tube may be too long. I dunno otherwise Im lost for a solution.
Once again thanks for all your input.

your knee hurting has nothing to do with ur top tube.
lower your saddle. you can do that in 2 minutes with a standard hex key. the numbers are useless for this. way too many unknowns, like how you pedal, toes down or parallel.. etc. learn to fiddle with ur saddle height and know what's good for yourself. dont' depend on the LBS to do soemthing you can do in 2 mins.
