New cleats, sore knee

Sharp twinge in front of knee, new SPD shoes. Does that mean to move the cleat forward or back? I forgot the rule of thumb for that particular problem.

okthx

It *could* mean that you should move the cleats back a tad. When they're too forward, your quads might be working harder, which could contribute to tendonitis at the front of the knee. I'd try moving them back, and see if that helps. Here's a really good link that someone posted a week or so ago, regarding cleat placement. I tried mine a little further back after reading this, and man, what a difference. http://www.cyclingnews.com/fitness/?...ers07-26#Cleat

The other thing that might be a possibility is if the new shoes are thicker-soled, effectively shortening the distance between pedal and saddle such that you'd be pedaling with your knee more bent. If that is happening, just raise the saddle a bit.

I agree with lawkd. In my experience, having the cleat too far forward makes my knee a bit sore.

Thanks for the explanation, lawkd, and the link too. Just learning the logic of it will help me remember that in the future. I've made the adjustment and will see how it works. I think i'll raise the seat a bit too, as I'd been riding with SPD sandals until now, and the soles on those were definitely thinner.

Cheers!

I've had more knee pains since i went to clipless 20 months ago. I have three different bikes and several different pairs of shoes. I'll share what i have learned over thousands of hours in the saddle.

1. Sometimes knee pain just shows up for no known reason. Seems like it is more likely to happen when i have been logging a LOT of miles, with little rest in between. Still sometimes i just get a pain, without any known cause. It always goes away.

2. I have a pair of Lake Winter Cycling shoes. I can't figure out what it is about them but they make my right knee hurt fairly often. Within an hour of using them for the first time I won't be suprised to have discomfort. I have tried moving the cleats all over the place, but still happens.

3. Most of my clipless shoes give no problem.

4. Saddle fore/aft/tilt, position is just as likely if not not more to cause knee pain. Play with it until your body is happy. Changing to clipless likely changes your postion on the saddle at least to some degree.

5. Clipless pedals are more likely to cause knee pain than platforms. I never had any knee discomfort until i went clipless, still i would NEVER go back to plats.

Hey, one other thing to check is the ANGLE of the cleats. If you feel like your knee is being forced to be rotated even A TINY BIT away from the naturally comfortable position, definitely adjust the angle of the cleats. Most pedals have a bit of float, which is rotational wiggle, to allow for a margin of error in this angle (SPD cleats have 5 degrees float, I believe).

Hmm... good point. I think mine were pointing kinda inward when I was riding. I'll fix them to point a little more forward, which feels more natural for me.

And thanks for the food for thought, Portis. I felt some weirdness the first day with my SPD sandals too, but I seem to have adjusted. There's definitely a funky break-in period for clipless pedals and cleated shoes, especially if you've been riding platforms exclusively beforehand.

If the knee problem persists, consider getting pedals that have more float. There is absolutely no sense in saving $100 on pedals to spend a few thousand in doctors and significant amounts of time in pain.

Pretty much all pedals have at least 5 degrees of float, at least if you get the right cleats. For example, with Look the standard red cleats have 7 degrees I think, and the black ones have ZERO float. On the other hand, SPDs have 5 degrees. Some of my Nashbar pedals seem to have only 3 degrees of float or so, but they are totally interchangeable with Shimano SPD cleats.

Personally I find that 3 degrees of float are sufficient, though I definitely notice knee pain setting in if my natural knee position is outside this margin. Having my knee even 1 or 2 degrees away from the optimal position hurts! Once you get cleans right, though, you probably won't ever have to fuss with the cleats again.

is the cleat on the ball of your foot? it's almost intuitive setting up SPD cleats and they have so much float fore and aft adjustment is more critical.
