Damn, how slow was that page to load on dial-up?!?

Bill "took like 30 seconds on cable" S.

About 5 seconds or less on AOL dialup.

Strange.

Caching on AOL. I got the slowish speed on RoadRunner, and I attribute it to
slow delivery speed from Oz. Any other dialup would have delivered it just
as slowly.

Quote:

In the heat of a full-power start, track riders have a habit of pulling
out of the pedals. The French team mechanics prevent this by adding a
bolt and nut to the riders' Look pedals that locks the engagement
mechanism shut. It's not pretty, and you really don't want to crash
while you're bolted in like this, but it works.

I've been watching this thread with quite a bit of interest.

First, my nebulous qualifications are as a sometime Cat 4 recreational
racer, but I've been at it off-and-on for 13+ years.

My observations:

It is bad to crash, period. I can't see how having your feet coming
loose can help. I'm not saying you personally agree with that, Ryan;
I just don't agree with that phrase in the quote you provided. Anyone
have any thoughts on that? (specific to the track; having the ability
to take your feet off on the road is a different matter entirely)

If your feet can come loose in a crash, they are that much more likely
to come loose when not crashing (ie, in the middle of the race), which
in my opinion cancels out any possible benefit you might gain by having
them come out during a crash - because the likelihood of a crash (either
yourself or those around you) is greatly incraased.

I've seen many more people pull out of clipless pedals at the track
than those with straps, I would guess 50:1. And at the worst possible
times (eg, in a sprint or in a pack, or on the line in a miss-n-out).

My personal choice is to use slotted cleats and straps, cranked down
hard enough that my feet don't come loose no matter what. I had one
(bad) crash at the track and considering the alternative (one or both
feet coming off the pedals) I will always want to be positively attached
to the pedals.

I'd like to try double straps - I got some new (NOS) Dura Ace pedals
earlier this year which I have yet to set up.

The wing-nut Look setup pictured above is tempting. The remaining
issue would be shoe stretch, which might necessitate straps. I've
been using Carnacs on the road (Ellipse and Quartz) for years now
because they seem to reduce/eliminate this problem. I just can't
stand shoe slop (ball of foot coming up off the insole of the shoe
while pulling up); it seems like such a waste of energy.

Q: What is the most annoying thing on Usenet?

Many people on this thread have mentioned that pedals with clips and straps
are less likely to release inadvertently in a start compared to clipless
pedals. I am not sure that this is actually accurate. First, there were
certainly pull outs before the popularity of clipless pedals. Just think
Dave Grylls at the LA Olympics in 84 or Shane Kelly in Atlanta. Second, a
friend of mine went to the Masters Natz and watched the seemingly endless
starts tabulating the number of pull outs and which pedal system was used.
His numbers indicated that traditional clips and straps pedals pulled out as
frequently as Shimano, Look and Time pedals but Speedplays pulled out less
frequently. I am not certain how rigorous his record keeping was or if the
numbers were statistically valid but this certainly fits my empiric
perception. This was before the pedals that combine a locking system AND
clips and straps like the MKS EKA. I seem to remember at some point seeing
a pedal that looked like a traditional quill but which had an SPD type
locking mechanism and a toeclip and strap, although I can't find anything on
them now. Seems like this would never release inadvertently.

Forget that: Cycling and 84 makes me think of Steve Bauer choosing too high
of a gear for the final sprint in the men's road race and losing to Alexi
Grewal by mere inches. Bauer was a much better sprinter and, had he not made
such a basic error, he would have easily won the sprint.

Grrrr!

It's still less likely, just not impossible. I think the laminiated
double straps (and their buckles) available today are much better than
the Alfredo Binda Extra straps we all used in the 70's and 80's.

I personally noted very few pull-outs in the starts I saw there this
year, among mostly the better riders I was watching. For instance, I
don't recall more than one team needing a restart in the Team Sprint.
(I didn't pull out of my Speedplays.)

You also need to consider who was pulling out, i.e. how good was their
starting technique, and how were their straps attached and tightened. I
saw some pretty dumb things being done in this regard.

Shimano. Still available at BusinessCycles.com. The cleat is the PD-64
and it's what I'll be using at Worlds for the 750mTT.

Wrong, you are talking about a Dura Ace 7400 track pedal (triangular shaped
platform) which uses the PD64 cleat. Mike is talking about a pedal similar
to that which is used on a spin bike that has a flat traditional pedal on
one side with a Shimano SPD style mechanism on the other side that takes an
SPD cleat. You then either just strap your foot or use a toe clip and strap

I'll bet if he could refine his data collection he would find that the most
significant variable in pull outs would be a worn cleat.

Exactly. A quill pedal in good condition, a cleat with a good slot,
and double straps pulled tight (really tight, as in no circulation -
if you are sprinting you want to feel like that strap is contcting the
bone - besides, you don't notice until you are done anyway) make it
IMPOSSIBLE to pull out. If you pull out, you've done something wrong.
One possible mistake is to have the buckles too 'high' instead of
close to the pedal, where they seem to have more leverage.

I know some will disagree, but the fact is that clipless pedals should
not even be permitted on the track in mass start events. They are
dangerous. Pulling out of your pedals is as dumb as rolling a tire
because you didn't glue it right. It's 100% unacceptable.

A funny thing about sprinting and straps:

Something funny used to happen to me only when I did sprint events.
After the heat, I would notice that a spot on my left thumb would be
bleeding. This happened every time, but never when I did 'normal'
track racing. This happened for years. It was the strangest
thing...

Finally I figured it out. While being held on the line, I would reach
down to tighten my straps. Because I was not leaning on the rail, my
left pedal would be very low to the ground (my right pedal is at 2
o'clock or so, ready to start), and the awkward angle I needed to
reach for it would cause me to somehow skin my thumb on the buckle.
However, because I was focused on the match, I never felt it even
once. Then later on the infield I'd wonder why my thumb was bleeding.
One of the last times I ever sprinted I saw myself skinning my
knuckle in this way and then I had solved the mystery. I remember the
peculiar sensation of seeing the thumb getting skinned as I was
pulling the strap, but not feeling it at all.

If I had started from the wall, I would have had my pedal in a
different position, and I wouldn't be pullling the strap down
absolutely as tight as I could. I also wouldn't be so totally zoned
and so would have felt the injury.

The only time I ever pulled out of a pedal in a mass start event was in a
madison once when I threw my partner in. There is definitely torque involved
in the exchange if you and your partner are not reasonably synchronized.
After the race, I increased the spring tension and that was the end of the
problem.

I guess I would be one of the people that disagrees. Most of the riders at
Alpenrose are using some clipless variety pedal, including some mountain
bike systems that I wouldn't even use for the road. Even so it is pretty
uncommon for us to see anybody have any trouble because of a pulled foot
except in starts where they are only causing problems for themselves. In
addition, as I said in my previous note, I am not so sure that clips and
straps are, in general, any less likely than other systems to pull out.
This is especially true if you add in the worn cleats and cheap straps
issue. I don't really see that clipless are any more dangerous than toe
straps and clips.

What I do think is unacceptable is falling down because of a pulled foot. I
have pulled a foot 3 times in mass start track races; once from a broken
cleat and twice because I was struck by another rider and the hit twisted my
foot out. Just relaxing the other leg and sitting down will keep you
upright. Falling because of a single pulled foot is generally a variation
of the "I forgot to keep pedaling" problem where the leg that is still on
the pedal is kept stiff and the rider gets pitched over the bars.

I have to agree with the sentiment. My experience is that most pull-outs
of clipless pedals are worn Look cleats. Maybe avoiding them is the
issue.

I disagree. Double-straps are almost foolproof. Single straps will allow
pullout, but decent cleats and double straps are very secure.

Worn clipless cleats are a serious hazard, worn slotted cleats are not.
They will still be held in by the straps -- and there again, all straps on
the market will hold well.

I disagree. Clipless pedals are less likely to give any indication of
wear that could lead to a pull-out, and much more likely to fail when
worn.

That is a bit harsh. People also pull out in sprints, where you have much
less chance of controlling the situation.

Very very seldom does the "I forgot to pedal" syndrome result in being
pitched over the bars.

It should be noted that there are pedal designs where an upward pull
_cannot_ release the cleat, only a twist. Egg Beaters are one example.
