1. Bianchi all carbon fork at the top of the headtube

2. Record rear derailleur; carbon part blew up

3. Dented a front Ksyrium rim running over something huge in the road at 45 mph

That's it, actually. (I won't mention some stuff that is commonly broken that I never have, as that's really tempting fate.)

1. Hinged 3ttt stem - the aluminum around the hinge (not the hinge itself) broke when I hit a dip. The handlebar stayed attached, but was rotating freely. I was able to very gently ride home.

2. Two spokes. One was on a very old pair of beater wheels when I hit a dip in the dark - the other was an almost brand new Velomax rear wheel, as I was coasting downhill on a smooth road. Clearly a defective spoke.

That's it - in about 40K miles in the last decade.

I got back into cycling after a 20-year layoff with a mountain bike in my early 40s. When I think of how I used to hammer that thing--out of ignorance more than aggression--I'm amazed it lasted three years, then I sold it for 75 percent of the new price. On road bikes, almost nothing--lots of spokes, until I realized I needed 36 on each wheel for my Clydesdale butt, and one rear dropout (probably a faulty part; I was--all together, now--"just riding along"). Everything else has either worn out or broken in a crash, and you can't count that.

I placed a small dent on my front Ksyrium this weekend. Groupride, nobody called a huge crater in the middle of the road and there I went. Its ridable and not out of true but the breaking surface is not completly flat at the point of impact. Any suggestions?

Once I bent a steel mountain bike frame and fork. The front wheel rim also broke. My front wheel went into a grate similar than those used for cattle. The bars were placed not crossing the road but along the road with enough separation for a mountain bike wheel to go in. This crate was at the end of a hill and I was probably going about 25 mph. As a result I had severe road rash in my left arm, leg, chin and eye brow. If it had happened in the US I could have sued someone but it happened in Mexico about 14 years ago.

Does wrenching count?

ITM quill stem- Over tightened the handlebar clamp and snapped the bolt in two. Luckily, it broke in the garage just before heading out.

Snapped a couple of Campy seatpin bolts.

I'm pretty close friends with my torque wrench now..

... snapped the spindle of a UN 72 BB...

... lost the spindle on two SPD 747 pedals (different times... same side pedal)...

Aside from these, just your generic wears and tears of daily cycling.

Be the bike.
Too many wheels to count.....MR_GRUMPY

All the wheels were broke in crashes except for one. That one I was riding with a group at night, when I managed to put my front wheel into another guy's rear changer. I sheared off 5 nips.
An old Cinelli bar snapped on me while I was stopped...
Finally, I snapped a Waterford at the top and down tube when I landed on it in a big crash in a race. (Not my bike........Not good for ribs either)

1 - XTR FD clamp - no idea how "it was like that when I got here."

1 - Calfee Tetra Pro seat tube - ham fisted mechanics and failing to line up the split in the shim.

1. More seatpost binder bolts than I care to admit, because I'm a doofus.
2. Several spokes over the years.
3. Campy 10 chain at the connecting link.
4. Lepper leather saddle. Rivets holding saddle to its frame sheared off. Apparently a design problem as I have since heard this is a common occurrence with Lepper saddles.
A sorry list if ever there was one.dzrider

2 seat post bolts, not the binder, the ones that hold the clamp.

Front derailleur cage folded up like an accordian and snapped the chain.

derailleur hanger

spokes - all but 1 under touring loads.

2 chains
wow, maybe torque wrenches are underrated?DougSloan
May 12, 2003 6:31 AM
I see several people are snapping bolts. I don't think I ever have. Do you all lube the threads?

I finally figured out why I was breaking binder bolts after some sage advice from Nessism. It seems that binder bolts have gotten longer over the years to accommodate larger tube diameters. My bolts were breaking because they were bottoming out. Adding a couple washers to the bolt solved the problem.
Morati Ti crankarm, EggBeater and Time ATAC pedals....SS_MB-7
May 12, 2003 6:54 AM
Morati Ti crankarm, EggBeater (cracked 2 cleats, pulled pedal off spindle) and Time ATAC pedals (broken spring clips, cracked carbon bodies, etc.). I'm sure there has been more. FWIW, I'm only 135lbs race Expert MTB. So far (knock on wood), I haven't broken anything on my road bikes, only MTBs.

DA front derailleur.bnlkid
May 12, 2003 8:02 AM
Other than spokes, the only thing I have broken was a clamp-on DA front derailleur. I think a big stick popped up into the crank or the derailleur was really fatigued from something else(it came with the used frame). It also snapped the chain. Had to walk 8 miles until I ran into someone with a chain tool to put my chain back together.
1 chain recently. Too many spokes ages ago nmPdxMark

May 12, 2003 9:31 AM
1)two chains

2)a non-drive side crank arm at the spindle hole

3)8 or 9 spokes

4)reflex rim cracked

5)rear derailleur- This was the worst. I loaned my bike to my friend while i rode my second bike. He had ridden over a length of wire and it got kicked up into the chain- then the pulleys and the whole derailleur got mangled and sheared completely off the bike...the cool part about it was that I got to see it all happen from behind.

6) faceplate on newton stem cracked

7)don't know if this qualifies but I received a case of clif shot gel and didn't realize that each of the packets had a small split on the bottom.....till I was 30 miles into a long ride. what a mess!!

Countless spokes.
A Campag bottom bracket axle
A Campag cartridge bottom bracket shell
Several old Campag rear axles.
Pulled a chunk off the drive side flange of a Hope rear hub.
Had a steel fork snap at the crown.
Snapped several Look cleats in half
JRA, not counting crashes?Straightblock

2 frames-my old race bike from the Nishiki/Suntour team cracked the RH chainstay at the dropout. I got the LBS to warranty it & the aluminum frame they got for me lasted about 12 years until it broke in half in a crash, so I'm not counting that one. I replaced it with a Bianchi Alloro that broke its front derailler hanger after less than 2 years. I've had its warranty replacement for about a year and hoping it lasts a lot longer than its predecessor.

A rear skewer broke during a u-turn on an urban commute and dumped me in the middle of one of the busiest streets in town (Blackstone Ave, for you Fresnans). Luckily I was half a block from work and two blocks from the LBS.

Split a 5-speed freewheel body halfway up Tollhouse grade. It let the outer bearing race unscrew & all the bearings fell out, and it locked up. I had to ride in semi-fixed gear mode for a few miles down to the nearest pay phone to have someone come up 35 miles from town to get me.

Another failure from the freewheel days-broken rear axles. I found two of them with the bike in the repair stand after rides while diagnosing a strange noise and poor shifting.

I thought the old freewheel stuff was fairly indestructible.

Blackstone? I wouln't even ride on Blackstone.

BTW, I do noon time rides fairly often. Interested?

I now work down in SW Fresno, south of Jensen & 99. A long way from where you are, I'm afraid, and mostly bad roads with plenty of truck traffic down here. Maybe a Saturday some time...an all-Celeste ride.

The cog carrier split, leaving the outer three cogs spinning freely; since this happened just as I was standing on the pedals at the bottom of a short hill, I did a low-speed Tyler Hamilton. At least I was able to ride home on the inner cogs.

Silver lining: suspecting that other components were also about to self-destruct, I became convinced that I needed a new "modern" bike (I hadn't upgraded anything except pedals since I had stopped racing six years earlier) so I went from friction-shifting 7-speed/sew-ups to an OCLV with 9-speed STI & clinchers. I felt like Rip Van Winkle awakening from a technological slumber.

on PP396s. Now riding the "Lance Pedal" and really like them. I just hope the spindle doesn't snap. I still have hesitations when out of the saddle and pushing hard.

don't tell me xtr is bombproof!
and those campy bolts. the worst part was taking the ramains from the lug.
control tech stem failure: it didn't break but the one of the threads just died.
lightweight skewers. i broke an xtr skewer but i crashed badly...

May 13, 2003 5:17 AM
Hey,

I was a little eager shifting into the big ring on the rear casette on a climb once. The mech skipped into the wheel, caught on a spoke, and ripped the deraileur in two (clean break in the metal). Bent the frame and busted two spokes and the chain.

I should get a pic of this beauty!
Cheers,

Just a seat during a wreck! Which was caused by a Deda stem failure!!!!!!!!
Quite a bit actuallySmiker
May 13, 2003 9:51 PM
The most recent item was the Deda Elementi bars on my road bike. Luckily it was just taking off from lights. I've broken numerous spokes, a SRAM 9.0SL RD, two frames (both MTB) plus cracked a road frame, broke a driveside MTB crank, I've broken Shimano and Wipperman chains, and I've also broken a Manitou suspension fork. PLus a few dead wheels on the MTB too.
