Knee pain from SPD pedals

Two weeks after starting to use SPD pedals one of my knees is hurting
a bit. The only adjustment I know of (besides the release setting) is
to move the cleat either forward or backward, whichever of the two
sets of screws is not in use.

I can also move ME on the bike by adjusting the seat position. Any
advice appreciated.

You can also adjust the angle of the cleats (i.e., to make your toes point
inward, straight, or outward). That is an important adjustment. You foot
position should be whatever is comfortable for you.

The fore-aft cleat position should put the ball of your foot directly over
the pedal axle or _slightly_ in front of the pedal axle, never behind.

Knee pain can be caused by a to high or low saddle. Too low usually results
in pain in the front of the knee, and vice versa. Raise your saddle until
your hips just start to rock when pedaling, and then bring it down a few mm.
Pushing big gears can also cause knee pain.

I my area they have a shop that does fitting for cleats also. They spend
about 45 minutes making sure you are set up right. They charge about $30.

I once helped install a person's first pair of clipless cleats. I was
lobbying hard for the pedal axle to be under the ball of the foot
(standard position). She insisted on a different position -
unfortunately, I forget if she wanted her foot further forward or
further back.

In any case, after about 250 miles of riding, she was having
significant pain under the kneecap. She then listened to me, we
adjusted them so the axle was under the ball of her foot, and the pain
soon went away.

As others have said, the side-to-side angle is also important. If
you're pigeon-toed and have your pedals adjusted duck-footed, you'll do
knee damage.

Cleats really do need precise adjusting, at least for many people.

If you could provide a little more detail on the location of the pain,
it would help.

Top of kneecap, bottom of kneecap tendon, medial knee (inside), lateral
knee (outside); each had specific causes and remedies.

As noted before, some pain comes from too low a seat/large forces, some
from too high a seat/overextension, some from improper seat fore and aft
adjustment (on the seat post), and some from improper cleat alignment.

You might want to take the advice I read somewhere and walk with wet
feet across a surface that will show your footprints to get the
orientation of your feet, and then differentially adjust your clips
to match.

You might also want to take the clips off and see just how they
can be adjusted. The ones I'm familiar with allow fore and aft
adjustment, both in the clip slot for the bolt head and in the shoe
socket for the bolt, along with rotary positioning via knurled mating
surfaces.

I've fiddled around for a couple rides to get the right cleat radial
adjustment.

I've used Road Cycling; Gregor and Conconi, editors; Blackwell Science;
ISBN 086542912X; which is a product of the IOC Medical Commission both
for the general biomechanics and specific medical advice.

Maybe something on this site can help....

What Art said. In every respect - SPDs are not quite the same as
platform pedals, so the saddle height will likely be subtly different,
but it took me a few tries to get the adjustment right on the cleats.
In the end I find that getting the inner side of the shoe parallel
with the crank works for me, but it's going to be different for
everyone.

Different shoes have different sole thickness, this can throw off your
seat height some, but it shouldn't be so much as to cause serious
trouble. Also, it should be immediately apparent to you if your foot os
too far forward or back. The problem may be in the angle of the cleat.

Many people have a natural twist to their foot as they pedal, this is
why many of the modern pedal cleats have a built in "float". That is,
when clipped in, the shoe can twist freely slightly. This also allows a
little sloppiness in setting the angle of the cleat, Too much
inaccuracy, however, can lead to trouble.

Ride your bike, and pay particular attention to the guilty leg. At any
point of your pedal stroke does it seem like your foot is trying to
twist out of the pedal? Note, this may be just a slight pressure. But
it should not be pressing against either of the cleat's "float limit"
anywhere during your pedal stroke.

If it is, the cleat is adjusted wrong and is preventing your foot from
twisting as it should. If this is so, determine which direction the
pedal is "fighting" against your foot and adjust the angle of the cleat
to allow your foot to twist naturally.

Thing one: changing to clipless will virtually guarantee you'll need to
adjust your saddle position. Your foot is almost certainly closer to the
pedal spindle than it was before, so you're extending your knee more. And
since changing your saddle height automatically moves it fore or aft, there
will be an effect on reach (albeit small) as well.

Also, clipless pedals center your foot laterally on the pedal. Were they in
the same position before? It's usually a good idea to carefully observe
where your feet "want" to rest naturally on a platform type pedal (and to
measure how far that position actually is from the center of the bottom
bracket), so that the position imposed by the cleats isn't too radically
different. The distance between the pedals is the "Q factor," and if you
used to ride with your feet towards the outside of the pedals and the new
ones are forcing them closer to the centerline of the bike, you may need
different pedals.

The angle of the foot relative to the pedal spindle is also important. If
you're naturally "pigeon-toed," for example, forcing perpendicularity can
cause stress on your knees. Cleats can be adjusted to accommodate a bit of
an angle.

Personally, I found that it was important to keep my knees a bit behind the
pedal spindle, when measured as shown here in section D:
http://www.coloradocyclist.com/bikefit/. If my knees were too far forward of
the spindle I had knee pain.

Thanks to all for helping. I will search around for a place that
adjusts the cleats - I have two ideas. First is the Time's Up guys
next Thursday night during the repair clinic. Second is a shop run by
the son (or grandson) of Francisco Cuevas, who was apparently fairly
well known as a frame builder. Their shop is just a few blocks off of
my normal commute home. It seems almost more of a club than a shop.

However, first I'm likely to not bike at all for a few days. Someone
mentioned in an earlier thread that the best thing for knee pain is to
rest it. Seems like good advice. This went from me wondering whether
something was hurting a bit coming home yesterday to limping around
nicely today. I just iced it and it is much better, plus I'm going to
take a few of those Darvocets that are left over from elbow surgery.
One at a time though.

I'm going to put the platform pedals back on temporarily and start off
that way after it stops hurting. Hopefully that will only be a few
days.

I wish I could tell exactly where the pain is but it is just somewhere
in the front center of the joint, a bit on the left side. I'll call
the Cuevas shop and seek their advice early next week.
