Well, that explains the creaking noise...
 

This happened on my way to work this morning. The pedal had been creaking lately. I guess I know why. I felt the bearings on both pedals recently and they spun freely and the bearings did not feel loose. I was planning to investigate further, and add some grease to the pedal cage joints, but hadn't gotten around to it. I rode about 7.5-miles without noticing anything unusual before the pedal simply detached just a few blocks from my office. Good thing I was sitting at the time and had clips to keep the pedal from bouncing into traffic.

what happened? what broke?

That just proves that if it came by itself, it doesn't always go away by itself! What is your plan for the home trip?

Looks like the outer portion of the pedal spindle broke at the threading. Glad you were almost home - it's always nice to have a mechanical close to your terminus.

Monday of last week I ended up walking 12 miles after my latest mechanical. Ugh!

The spindle broke. About half of it is still in the pedal body.

Fortunately, I can take BART (public transit) most of the way home. Chances of finding a french-threaded replacement pedal at the LBS are slim.

[MENTION=175208]gaucho777[/MENTION] - My dad told me his first bike only had a spindle on one side for peddling. The other side didn't have anything to put a foot on! I bet you could make it home, but it would hurt your MPH average for the month!

I'm not so sure thats it...

Yup, I rode bikes like that as a kid.

Time for some one-legged pedaling drills!

I wonder if it's because the spindle threads might have been cut in and not rolled on......
Rolled on threading is less likely to fail from stress risers at the threads.........

I am pretty confident that the pedal shaft broke at a step-down in diameter.
These pedals do this. Granted with many miles, but it is by the nature of the design.

Retap it for English. I did that to my TA and have never regretted it.

Pushing a bike for twelve miles? YOUCH!!

Luckily I was wearing my Sidi touring shoes and not cleats, but yeah - my arches were still screaming when I got back home at midnight-thirty!

Maybe not at your LBS, but I don't think that French threaded Lyotard pedals will be too hard to find in eBay.....

Interesting and coincidental thread! I've also been reading a few mentions by RobbiT and his mysterious creaking CF bike.

So now I too have a creepy-creaky that started yesterday. Though its on my recent build of a vintage steed using an aluminum cottered crank. Because of the particular crank, I've been fairly easy on it though caught in frequent rains and high humidity. Pedals are some old Lyotard tour (steel cage / aluminum housing). I can see the flex in the rattrap pedal cages when strapped in (not meaning the toe clips), so my first thought is the steel joints, but now it might be something worse.

Time to move up from those Lyotards. These were just listed on eBay today (not mine). The "METRIC" marking on the box means "French" thread:

^Thanks for the tip. Those look like nice pedals.

I've been casually upgrading the bike with Campagnolo parts (generic seat pillar-->NR post, Weinmann brakes -->Campagnolo NR levers/Gran Sport calipers, Valentino FD --> Campagnolo Record FD, rebuilt wheels with Gran Tipo hubs), so if do splurge on new pedals I'd like to find some Campagnolo Record pedals to go with the rest of the group.

Right as usual. The spindle broke about halfway along its length, at the step-down, before the threads.

Just got back from a lunch trip to the LBS. I assumed wrong on the threading. The rest of the bike is Swiss/French threading, but the crank is a replacement put on by the previous owner. No markings on back of crank arm or pedal spindle. Turns out it's standard threading on the TA crank.

I have some similar Lyotard pedals at home, as well as a pair of (non-servicable) Atom pedals. Not 100% sure on the threading, but I hope I have something in the bins that will work for now.

But on the way back, I dropped the broken pedal and ran over it and got a flat! Ugh, not my day.

Ha! That pedal has it out for you!

I'm with Jim... I'm thinking something else is making that noise. Only when you pedal? Maybe your fork's bent.

If it were me, the creak would be me.

Yeah, but it's better than the entire bicycle having it out for gaucho.

Nobody likes to [be] up the creak.

What type of pedal was it?

Lyotard 460 I am pretty sure. There were some variations to the spindle, Cad plated, Black oxide and I have even seen chrome.
So, there may have been some article number variations.
