HI Everyone

I just got a new road bike and put my time mtb pedals on it.After about 20miles into my ride i developed a pain on the inside of my right knee where the joint is on the side.Any suggestions.Everything else on the bike seems to be spot on.

Thanks To Everyone

If your experiencing the pain and its the same pedals do the following:
1) check the saddle height by measuring from the middle of the crank bolt to the middle of the saddle and ensure they are EXACTLY the same. I have 4 different bikes; 2 road, 1 track bike and 1 mountain bike and this is how I do it. It works especially good because between my road and track bikes I have the same Shimano Dura-ace pedals on each of them. Then my mountain bike with Shimano 959 I have to raise it minimally.
2) make sure your not grinding in the biggest gear instead spin at 90-110 rpm. You can either by a cheap cadence computer or just count the # of pedal strokes on one leg in a 10 second period and multiply by 12 to get your rpm so you should be between 7-9 I think.
Hope this helps!

Nick is right. Check your saddle height first. Either too low or too high will cause knee pain. The second cause if over stressing it, so if you haven't been putting in a bunch of miles and just went on an epic, or are pushing big gears this will cause this. Rest, aspirin, stretching and warm up / warm down will help. Make sure you 'spin' and work up to doing longer rides.

Actually, I am experiencing the same problem and it has been suggested to me that the "Q factor" may be in need of adjustment.

The Q factor, as I understand it, is the distance from bottom bracket to the pedal. It also refers to the angle created between your knee and hip--well, actually, where the knee connects at the hip--pardon the lack of anatomical terms.

It would be good to see if anyone else can comment on this aspect of the problem.

Q-Factor is a method to try to keep your hip, knee and ankle in line as you look at it from the from. Bigger people (and most women) have wider hips and therefore need a wider q factor. Set your bike on a trainer looking into a mirror. As you are pedaling are your legs relatively in-line on a vertical axis. If not you may need to adjust. Usually you can slide the cleat side to side to help alleviate the problem or find a crank with a wider reach. The old syncros revolutions had a wide q-factor and work well for people that have this problem. If you thigh angles in and you calf angles out this willc ause knee problems.
