Speedplay spindle wear (grove)

I have never heard of a Speedplay spindle breaking due to wear caused by the springs (although
someone will now post to contradict me). Indeed, I continued to use one pedal off and on for more
than a year after I cut a 3-4 mm deep groove into the spindle in just one 20 mile ride by installing
a cleat spring incorrectly (front for rear or vice-versa). That said, I think you are wise to be
concerned, and I have since retired the pedal in question.

Given the mileage you've accumulated on your pedals, it might be time for a rebuild (or replacement)
anyway, in which case you could have the spindles replaced - contact Speedplay to see if this might
be a cost-effective thing to do.

This is a recurrent thread. I've used my Speedplay X/2s since early 1994 and there are no grooves
worn in the spindle. I've always wondered how that seems to happen to so many people, yet I have not
ever had it happen with my pedals. What's the variance?

I was googling for info and came across a thread that suggested pronation as the source of downward
pressure on the inside of the cleat. I suspect a non-neutral foot position is the source of the
problem. My concern is at what point is it a safety issue. The wear begins to occur pretty quickly
and is refreshed with each new set of cleats with round springs. I copied Speedplay on my initial
post. I'll be curious to see what their response

Interesting. I positions my cleats as far to the outside as I can without hitting the cranks with my
feet/heels to minimize the Q factor as much as I can.

Now, I've never really understood the terms "pronation" or "supination" since my dictionary's
definition refer to hands not feet ("pronation" turning the hand palm-down using the pronator muscle
and "supination" turning the hand palm-up using the supinator muscle). So as far as feet go I'm
guessing people who pronate tend to walk with their weight along the medial (big toe) side of their
feet and supinators along the lateral (little toe) edge?

If that's the case, I am of the latter variety. My walking shoes always wear out by my little toes
and the outer sides of the heels. So perhaps this has the effect of raisng the inner edge of the
cleat away from the spindle.

Tim, you are a pronator (I am too), and you need a good dictionary. For my feet, I use Big Meat
wedges -- wonderful things. I think pronation and supination is a red herring here -- the design of
the cleat is such that angling the shoe inboard or outboard is extremely limited, even with old worn
springs. Is the spindle the same as the pedal axle? I have over 20,000 miles on my X-2's with no
grooves at all in the axles (though there is a bright band where I have shined the metal by clicking
out). I have been though several sets of cleats, and one replacement pedal body, but the axles and
the bushings are in good shape. Surely the axles should *never* get grooved. To the poster whose are
-- don't give up on this until you get an answer.

If Tim wears out the outside of his shoes, he's supinating (or under-pronating as the running shoe
gurus have come to call it; pronators roll inward). I'd bet Tim also has high arches and replaces
his cleats in a timely manner. But regardless, as another nine-year user, I can say the Speedplay
spindle groove will happen to anyone if the following is allowed to occur:

The springs are allowed to wear sufficiently before replacement, thus not fitting tightly in their
engagement grooves. This allows the shoe to rock laterally when the cleat is engaged, not only
wearing out the springs further, but also the cleat and composite pedal body, which enables the
springs to contact the spindle, wearing the groove. The pedal body will wear enough on the inner and
outer surfaces from the rocking to make new cleats/springs insufficient to stabilize the shoe,
worsening the wear rate on the new cleats and old pedal body. Then it's time for some replacement
parts or new pedals.

It's actually such a common occurrence that Speedplay has pre-grooved their X3 pedals. For example,
have a close-up look at the spindles in these at Performance:
performancebike.comlarge photo.htmlOpen ↗. If the groove is deep
enough, it can certainly cause a spindle to fail, but a minor one is not likely to be worth much
worry. There are thousands of grooved Speedplay spindles out there, you can be sure.

Speedplay recommended that I replace the bowtie plates at $40.00 per pair of pedals. The tech
suggested that slight wear of the spindle was probably not an issue. However, their official
recommendation was a spindle with any wear should be replaced. If your feet pronate then you will
eventually cause the underside of the aluminum bowtie plates to round which will allow the cleat to
rock and the steel spring to run against the spindle. Bill Brannon

A friend of mine wore a really nasty groove in his X-1's and was so worried about it that he bought
a new pair. He did have the MOST worn-out cleats I have ever seen. At the same time, he bought a new
pair of very expensive Carnacs, thinking that perhaps his Time shoe sole profile had caused the
problem. After just a ride or two, he noticed that he had a new groove starting on the new pedal
spindles. As I looked at him ride, I noticed that he had his cleats set all the way to the outside
of the shoe (I suppose to bring his feet as close to the crankarm as possible, reducing Q-factor?).
This caused him to pronate pretty badly under low cadence, high tension efforts. I had him recenter
the cleats just a bit, in order to bring the cleat more under the center of his foot. Voila! No more
scoring of the pedal spindle & much less pronation (and over-pronating like that can't be all that
good for you if it's not a natural occurrence.) He really didn't have to move the cleats very far,
either, so it didn't take him very long to get used to the new feel. I wonder if sometimes we don't
take things a little too far in our quest for performance. I guess someone somewhere mentioned that
it is a *good thing* to have your feet as close as possible, and some of us took it to heart without
realizing the potential consequences. I often wonder, too, what effect close foot spacing has on a
woman, who has a more extreme angle from hip to knee in the first place. Anybody want to chime in?

If you install the cleats w/o the LOOK spacer, just the four bolt of the cleat onto a Time shoe,
this can happen.

Interesting. As far as I can recal, all of my Speedplay X pedal cleats are mounted via a LOOK
adapter. I can't visualize why this would make a difference, however.
