I did. My shoe pulled straight out. Brand new Shimano cleats on Shimano pedals.

My knee hit my handlebar. Then I broke my collarbone. I'm off the bike for a month.

Holy crap. Sorry to hear that.

How will you commute to work?

Ouch!

Thats nasty...how high was your tension set? I don't think I've ever seen anyone pull out of a pair of SPDs...

Yea this is why I sold my SPDs after only a few rides...I never pulled out but it sure felt like I was going to and that was with the tension cranked. I MUCH prefer the Time ATAC for a MTB style pedal.

Now the SPD-SL on the other hand have been very secure and do not have a similar feeling.

Ouch! Sorry to hear it. Hope you heal quick.

All the way up.

I'll be getting a ride to work with a generous coworker and friend for the next month.

Ow! That sucks. I've never pulled out, and I've been using them for about a year. Maybe you got a lemon set? Either way, sucks man. Get better.

No way! That's too bad. So sorry to hear about it! Pop out on the up pull? I have a slight bit of unwanted cleat movement on teh up stroke with SPDs. I'm gonna be switching soon to whatever the forum suggests ( https://www.bikeforums.net/road-cycling/237234-pedal-poll-ultegra-vs-keo.html )I've heard people complain about up stroke movement on keos. I wonder if they would have a similar problem.

For some reason a tiny 2005 TDF moment is cemented in my memory. Lance's solo TT. Just after exiting the ramp he popped out for a moment on an up stroke. Lucky for him there was no crash. I don't know why I remember that so well.

That sucks, but yeah thats usually one of 3 things:

a) tension
b) not enough float (i.e. you unclip because of too much heel angle)
c) not clipped in the first place... I've had this problem with a single shimano pedal... it felt like it was clipped it but it wasn't and would eventually release. finally realized that if I didn't hear a click, it wasn't good.

Otherwise I've sprinted hard enough to bring the front wheel off the ground w/o unclipping, and MTBers race on them all the time.. so...

I've been using SPDs on some of my bikes for almost 2 years. I have actually experienced this before, on other sets of SPD pedals, but I've never fallen because of it though. I can only duplicate it with a monster (pretty much max for me) effort, and even then, less than a quarter of the time even if I'm trying. This level of effort never occurs during normal city riding, and not even in many races. I was doing a specific training drill in which I was trying to produce the instantaneous maximum possible torque.

I have put many similar efforts into my Look pedals and never once pulled out.

Ouch dude! Sorry to hear that. I've popped out of SPDs before, but the tension wasn't set too high and I was usually trying to skid the fixie when it happened. For my style of riding, they've been fine, but I'm not a racer.

a) The tension was all the way up.
b) I've been using them for years. I know how much angle is required to unclip.
c) I've experienced this too, and I can tell the difference. I had been clipped in long enough that I would have noticed.

I have actually done this before. Give me a brand new set of cleats and pedals and 15 minutes in a parking lot on a high enough gear, and I can pull my foot straight of the pedal. I actually demonstrated exactly this for the owner of my LBS who was also skeptical.

I'm pretty certain this wasn't anything I did wrong. I race, and I have a halfway decent sprint so I can put out a decent amount of torque. If you still really think this is impossible, I'll get some video in a couple of months. If I'm prepared for the possibility I can cope with the pullout. This time, I forgot.

This is the reason I ride Speedplays. Virtually impossible to pull out inadvertantly.

I know I don't sprint like the Madmad that I could using SPD's...

However even in the most stump pulling of required low speed torque climbing a techincal single track on MTB, I have never pulled out of SPD's, but the pedal stroke then isn't like a thrashing motion either.

I've had it happen once or twice on mine. The first time I probably had the tension too low, the second time was one of those "wow, I'm getting good at these intervals" moments right before I took a saddle to the crotch. Now I have them at max tension and if it happens again, upgrade time.

Anyone know if Eggbeaters are immune to this?

i've popped out twice in races. once i tried to attack the group and when i sprinted off the front my leg shot forward and i nearly toppled. thankfully my 10 second lead was enough that i could veer over the side and clip back in before rejoining the group.

the other time was while i was getting ready for the sprint. not even out of the saddle yet, just that initial surge toward the line. i instantly dropped about 10 posititions...thankfully the guy behind me was alert and went around. scary stuff though.

Ouch. Not a good time, heal fast. I pull out of my SPDs all the time, if you pull up hard enough they let go.

I popped out twice, but the cleat was at a little bit of an angle and would come out on hard pulls. Since then, I've had good look with them on my fix gear bike.

be careful with those spd's when you dial it up to 400w i guess... bummer!

Hope you heal quickly.

I know you are kidding...

but...

400 they can take no problem. I'm pretty sure the danger zone is somewhere over 1000 or 1200 watts. I'm guessing it's actually related to torque, but I do have a power meter on one of my bikes, so I know how much 400 watts actually takes. And even though I don't have one on the bike I crashed, I know I was way over 400. From feeling alone, I would estimate I was between 1000 and 1300 watts which is around the top of my instantaneous range. I can only mantain those numbers for a few seconds, but it's long enough to "do a lot of damage". Pun intended

Thanks. I go Thursday to find out if it's healing properly or if they have to re-break it. Feels good so I'm optimistic.

That is just nasty.
