@ascentale @xtaran @bikenite A2: I had a Specialized Ruby saddle crack — during a track race. I liked that saddle, but after talking with other women found out it happened with them frequently. Before my then-mechanic made me a bespoke shim, I had a seatpost sink, also during a race. That lovely custom-for-someone-else track bike has, uh, weird tubes. #BikeNite

@ascentale @xtaran @bikenite A2. Before I knew better, I bought a cheap department store bike. While I was pedaling from a stop at an intersection, the entire rear axle got bent out of shape and wouldn’t rotate.
@twoodford @ascentale @xtaran @bikenite A2. An ex had a cheap department store bike and went over the handlebars when the forks suddenly bent. Praise helmets

@ascentale @xtaran @bikenite A2: I’ve snapped half a dozen bb spindles, a front axel, and once exploded an Mtb shift pod with my knee. I twisted (along the long axis) a set of cranks. Broke a seatpost clamp, bent saddle rails, and have snapped two frames and ovalized the bb shell of a third. I’ve bent half a dozen brake rotors.
These are what I remember. I’m sure there are bins of cooked parts in the garage that I don’t recall.

#bikenite@ascentale @xtaran @bikenite Oh, right- I grenaded a rear hub. Got it to spin in both directions, and on disassembly found I’d both broken the ratchet ring AND ALSO broken every single place a pawl was mounted in the freehub. Just a wild failure mode. #bikenite

@ajft @ascentale @xtaran @bikenite
A2. I completely forgot I had that happen on one of my first cheap department store bicycles. Completely forgot about that bike. I think I blocked it out because it was such a bad experience.

@ascentale @xtaran @bikenite A2. There’s a little plastic piece on my main bike (Tern NBD) that attaches to the gear hub. After what turned out to be quite a few warning signs last year, it basically just snapped in half as I went over a bump. Took a while to get the replacement part in, as it wasn’t something my LBS kept in stock. Irksome to be sidelined for a small plastic piece! (I’m sure it has an official name, I just have no idea what it is.) #BikeNite

#BikeNite A2:
Besides the numerous flat tires, and several shifter cable breaks, the only less usual part failure has been a broken spoke when a thick twig hopped up and caught in the stays. But that happened 17 or 18 years ago. Since then I am more careful with running over twigs -
@oheso @ascentale @xtaran @bikenite
Pretty sure it was a manufacturing defect! -
@ajft @ascentale @xtaran @bikenite back when I was racing and buying the lightest everything, I had seatposts break. Similar experience, awwwwwkward ride.

A2: Not an ordinary flat: Second year of using my Schwalbe winter tyres. Easy, find a warm halway and fix it. Second time was -20C or so, find another warm hallway. I mainly bike at night so running short on warm places. It kept happening and I thought it was my old rubber so changed the tube. After a few weeks this one starts failing too. I have a closer look and it has about 120 evenly spaced holes. The spikes are working themselves through the tires...
#BikeNite@eq @ascentale @xtaran @bikenite I thought oh studded tires I can make that with little wood screws and some duct tape and a tire liner to cover the heads.
This was a terrible mistake. That thing ate tubes like whoah. -

@ascentale@sfba.social @xtaran@chaos.social @bikenite@fedigroups.social A2: May not be totally unexpected, but my saddle suddenly tilted backwards while I was riding relatively fast. Sure scared the heck out of me! As it turned out, I hadn't tightened the saddle nearly as much as I was supposed to (5 Nm vs 12 Nm)... #BikeNite #MastoBikes #BikeTooter

@ascentale @xtaran @bikenite A2. I was a bit surprised to have a derailleur pulley wheel come off on my mtb. Luckily it was towards the end of my ride and pretty much all downhill to the finish.

@silvermoon82 @yantor3d @ascentale @xtaran @bikenite yikes, seems like some quality control issues with the assembly and/or parts

I trashed a freewheel ratchet too - and Mavic the cheeky bleepers tried every trick to avoid replacing it. Ended up sending a letter before action to show them I wasn't fooling around.
Tangled a rear derailleur into my spokes and wrote off entire bike.
Saw someone snap a front fork - that was horrid. He was super lucky/catlike and rolled head over heels down the bike lane. But it was instantaneous and he went from doing 30km/h to hitting the deck in no time

Had that cable issue on older Shimano brifters. I think there was a sharp edge in there. I eventually replaced with bar-end shifters

A2.
I tend to mash more than I spin, and I was even worse about that when I was younger.
One day, starting from a standstill, standing on the pedal as usual and probably placing too much force on the handlebars - they snapped.I walked in with the pieces to the LBS and just asked for a new handlebar as if it was just another Wednesday.
As an aside - which doesn't fit the question because firstly it didn't happen to me (I just happened to be nearby and saw it), and secondly _technically_ could be described as a "flat", was someone in a (somewhat slow) social ride who had the front tube blowout with such vigor that the tube somehow managed get stuck between the wheel and the brakes or fork (or both), locking up the wheel. We might just have been going slow enough that the rider managed to avoid getting literally thrown over the handlebars, but he did come down hard in any case.
I didn't know a tube could do that... -

@lopta @ascentale @xtaran @bikenite@dgodon a friend thought I was just careless until he got a power meter. The rotor on his wind trainer exploded at about 1300W. It was exciting!
Bikes mysteriously failing for no reason when I rode them made more sense to him after that.
Also explains me considering 150kg on the load bike perfectly reasonable.
Luckily I'm older and wiser now. Or fatter and less fit. Same same.

@dgodon @oheso @silvermoon82 @ascentale @xtaran @bikenite In my case, I had just had it in the shop to install a range extender, which requires you drop the motor. They might not have fully tightened the screws when putting everything back together.
