Looked painful. No word on the brand or model of cranks.

BMX Components Videos UncategorizedBroken Sidi Dominator
One time I remember seeing a guy at a cross race fishing around in a mud puddle for his Dominator buckle. I think I’ll stick with Carnacs with big velcro straps… Via Bill’s Web Site
Cracked Mavic MA3
I’ve ridden Mavic rims for over 25 years–G40s, MA40s, MA2s, GP4s–and this is the first one I’ve had an issue with. This rim came on the rear wheel of a wheelset I bought from Cambria for my commute bike (a Surly Cross Check). The wheels have 32 spokes laced 3x to Ultegra hubs. The straight gauge 14mm DT spokes wouldn’t be my first choice, but the complete wheelset was a lot cheaper than I could have built up myself. I probably had around 5,000 or 6,000 miles on these when I first noticed the cracks. Turns out the cracks around the eyelets are pretty common on these rims. I wouldn’t say the spoken tension was terribly high. Just a bad product from Mavic. This is the worst eyelet, but there are cracks starting around one a second one. I’ll probably rebuild it with an Open Pro or something like that. More pics after the jump!
Cracked Thomson Seatpost
For some reason, the owner of this Thomson post wanted to keep riding on it. If you see a crack develop like this on your seatpost, you should replace it immediately, like I did when my Syncros post developed a crack. Otherwise something like this could happen.
Broken Campagnolo Super Record Ultra Torque Crankset
This Campagnolo Super Record Ultra Torque crankset broke and fell apart while RoadBikeReview user Knakhemel was riding across some cobbles. Luckily he was able to release from the pedal at the same time and didn’t go down. Campy came through and replaced them with the new titanium version. Nice work Campy!
Cracked Syncros Seatpost
I had this post on my Ibis Mojo (the old steel hardtail from Sebastopol, not the new carbon full squish from China). Syncros wasn’t my favorite brand, especially after the stem breakages and recalls they had in the early 90s. And I knew that these posts were known to develop cracks. But there weren’t a lot of options in the 28.6 required by the Mojo. Anyway, mine started to crack shortly after I moved to Seattle and started riding the root-infested trails they have up here. And to be fair, my seat is slammed back pretty far. Still, I only weight 145… As soon as I saw the crack, I replaced the post with a cheap Kalloy Uno until I could score a Thomson.
Cracked Carbon Handlebars
BustedCarbon.com has a great collection of broken carbon stuff. Check out these Specialized bars that cracked while JRA. Bummer!
Broken Steer Tube
It is nearly impossible not to crash after your steer tube breaks Just ask this guy. Luckily he didn’t get too badly hurt. Looks like a Specialized.
Broken Race Face Turbine Cranks
Over on Flickr there is a whole group devoted to bicycle part failures. This pic was snapped by SoulRider.222 with no explanation given. Looks pretty dramatic!
Cracked Masi Vincere
This guy bought a new Masi in 2003, rode it for many happy miles. Then the chainstays started to develop cracks (both!). He went back to Masi to see if they would cover it under warranty. But he didn’t have his receipt, so they told him he was out of luck. And the moral of the story is…? Two more pics after the jump!
