  1. 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.

  3. 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.

    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.

  8. 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.

    This is what happened to me. My left foot tracks straight ahead, but the
    toes of my right foot want to point slightly away from the bicycle. If the
    cleat doesn't allow this, the knee hurts on the inside. So, you can adjust
    the cleats to fit the natural turning of your feet.

    Very helpful. Thank you. When I go back to SPD then I will do higher
    rpms and lower gears. I'll also find out how to adjust the float. It's
    only on the left knee so something is different on that one. No, that
    doesn't add up. Neither were a problem until yesterday so it is quite
    possible that the right knee will be causing a problem in another few
    days. Adjust both.

    That site sure is overkill. Lots of stuff there. It's hard to get a
    feeling from the three letters that I read but I will try moving the
    cleats around until I get a better feel.

    Part of my problem last week was that I was riding with a flat, sort
    of. I had noticed that I was just dragging along, in fact I looked at
    the brakes to make sure that they weren't rubbing. The odd thing was
    that the rear tire looked fine when I looked down at it.

    Later on I checked the tire and it certainly felt low. I checked the
    tread and found a nice sized piece of glass, so I pulled it out. But
    the tire was far from flat, so I pumped more air into it and continued
    on my way. When I passed a bike shop I used the hose to really fill
    it.

    Sunday I had some time and did find a slow leak where the glass had
    managed to just nip it. So I patched it and now it's fine. But I think
    that I was really putting more pressure on the knees than normal.
    Hopefully this weekend I'll get a chance to mess around with the cleat
    position. In the meantime I put back the old pedals for the rest of
    the week.

    It sounds like, you need a decent floor pump and gauge. It is a good
    idea, to check your tires before every ride. Looking at them isn't the
    answer.

    At this time of year, I ride 4-5 days a week. I check and top my tires
    off, before each ride. It takes, just a couple of minutes.

    Sure, I have a nice floor pump and gauge, but I don't take them with
    me. I pump them up every week and check each day just by squeezing.

    This leak developed somewhere during the inbound commute or perhaps on
    the outbound, but it certainly made itself evident on the outbound.

    ^^^^^^^^^^^^^^
    Certainly a low tire will increase pedaling effort, as does a hill, a
    headwind or a higher speed. I tend to ride at a speed which puts an
    acceptable load on my legs and lungs. A low tire would tend to make me ride
    slower at the usual knee pressure, so I wouldn't expect to develop knee
    trouble from a low tire. Doesn't that seem logical to you? Or do you drive
    yourself harder to keep speed, regardless?

    No, I was definitely going slower. Still, I was feeling the knee at
    that time so that was also why I was going slower.

    I'm going to resume biking tomorrow. It promises to be wet.

    Reread, the post, I was replying to. You make it sound like your tire
    problem was during the course of a week, not a single day.

    I really don't think that squeezing tires gives you an accurate
    reading of air pressure. Bike tires, or more correctly their tubes,
    lose a little pressure everyday. By the end of a week, you can be
    down, 10-20 pounds. And each day when you squeeze them, they feel very
    close to the day before.

    Do what ever you want, I believe that checking and topping them off,
    takes only 2-3 minutes and is a simple, worthwhile thing to do.

    Rotation. need to get the rest position of your foot right, because even
    with float there is a spring that centers the cleat. This caused me
    problems when I used spds, but now that I use Speedplay Frogs, it's no
    longer a problem.
