A2:Brand new one for me this week:
in a nutshell (long story, else)
lower idler on rear derailleur seized up. the tension idler.
on this derailleur, it's a sealed bearing cartidge style. Not bushings.
Too much winter road treatment slop. bearing froze.
This was a 'full-stop, cannot continue' failure. Took me a while to figure it out.
thankfully, the weather was nice & sunny.

A2. Domino effect, had to laugh abt this personal misfortune recently so have one on me too ...
[.|.] - prev outing - chain-ring guard came loose, removed for future refixing. Forgot, then mislaid it...
[:|:] - first steep section on next outing, shoe-lace gets snagged on top chain-wheel sprocket, forcing stop.
[:.|:.] - while retying, still straddling bike, it begins to fall, I grab handlebar hard in unusual place - happens to be the battery V meter. Nasty smell and no assistance.
[::|::] - ride the bike back to base, unladen, so decide to take a shorter more scenic trail. This involves riding over fallen trees. Small branch snags in wheel and trashes mudguard. Limp rest of way back.
[:.:|:.:] already had enough, I give-up the ride on the only non-rain day for a while, eat rations and surrender to another trip in rain another day [see A1]
[:::|:::] you get this

@silvermoon82 @oheso @yantor3d @ascentale @bikenite #BikeNite A2 follow-up: Brompton G-Lines are known for their right pedal (and only the right one) to come loose after a while if you hadn't fastened it more than ex-works. Happened to me after maybe 1500km. Knew about it and noticed the loosening screw before it fell off.

@ascentale @xtaran @bikenite I guess the third time you snap a Hunt Wheels axle you can't call it 'unexpected', but that's been my most regular occurance over the past couple of years. I've have 2 seatpost clamps go in 18 months too. All rather boring really. A2 #BikeNite

#BikeNite A2: I've had the opposite: The hub seized completely. No cassette freewheel, the wheel wouldn't turn. I loosened the skewer so I could walk the bike to the LBS.
I noticed resistance to pedalling over a few kilometres and finally stopped, in the dark, at a park bench under a street light, to pop the wheel out, thinking some debris was caught in the hub.
Bought a new wheel, cheaper than getting the LBS to lace in a new hub, and faster than doing it myself.

@ascentale @xtaran @bikenite A2: the pinion gears in my Mt Drive shattered. Which turned out to be a known issue and it was replaced under warranty. Luckily I could pop a standard BB in and keep riding.
Technically One Less Ute failed in an unexpected way, but the design was "I wonder what I can get away with" so it was doomed from the start. A 25kg Long John is optimistic, making the load bed 1.5m long and putting 150kg on it is really pushing the envelope.
@moz
failed mountain drive?i installed (fsvo) a lot of schlumpf drives of various flavors back in Florian's day.
Florian insisted all the drives shifted fine & safely under load.
Me?
wasn't convinced.the only one we ever had fail was a mountain drive.
& I know the client would shift under hard loading.
They alwys felt (to me) like they took a bit'o time & movement to mesh properly.

@ascentale @xtaran @bikenite A2. Other than me, I’ve broken a derailure cable (annoying), and broke two chain links (the first I got a ride home, the second was a long was a long walk in cleats). My bike has been rideable after several crashes, so annoying but no breakage). #BikeNight
-
@ascentale @xtaran @bikenite A2. One of my cranks fell off once. Couldn't find the bolt - I think it had come loose and fallen off miles earlier.
Flat tires don't count, but what about the time I had a flat tire and my hand pump _fell apart_? Don't buy cheap tools...
@yantor3d @ascentale @xtaran @bikenite oh, I’ve had two flats with non working pumps, two more long walks home… #BikeNight

PS:yes, shattered planetary gear.
threw bits all throughout the mechanism. big headache.Florian sent all the stuff i needed to repair it, no charge. & explained how to set the timing on the gears.
Else, I'd have never figured it out. lol

#BikeNite A2 the seatpost clamp bolt broke and my saddle sank/slid out from under me. Luckily I was not turning and had both hands on the handlebars, managed to stop safely and pickup the clamp parts. Unfortunately my kid was 15min late by the time I had rigged up a strap to hold the saddle over the post (had no tool to take the post out!) and rode mostly standing for that last ~2mi.

@ascentale @xtaran @bikenite A2. I rode a cruiser with a coaster brake and no front brake exclusively in college and the only bike shop was an hour and a half car ride away. Somewhere in senior year, my chain started popping off, which meant that in order to stop, I had to use my shoe, or, if I was going downhill, find a soft place to land.

@daihard @ascentale @xtaran @bikenite
A3. Yes, that's happened to me a few times when I have ridden too fast over a hard-to-see small kerb without lifting myself in time. It's quite close to home though, so I can usually bang the nose of the saddle down and get back OK.
Edit: typo.
@etp@indieweb.social @ascentale@sfba.social @xtaran@chaos.social @bikenite@fedigroups.social Glad you were able to get home without much more trouble. I re-tightened it with my multi-tool and rode to a nearby bike shop to ask if anything was wrong. They asked me how much I tightened the saddle clamp, and upon hearing "5 Nm or so," they were like "Aha! That's most likely too loose." They got the right torque spec for me and tightened it accordingly.

@xtaran @bikenite A2. A couple of less-common failures:
* Spokes pulled eyelets through rim
* Spokes pulled through hub flange
* Cracked saddle rail
* Crashed with car, fork broke at steerer tube!
* Headtube cracked over time (aluminum frame, as discussed last week)
* My partner had a Mavic hub death squeal. Something happens with the palls in the freehub that makes a terrible sound. -

Torque wrenches are not something I have yet had to deal with.

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...@parsley @ascentale @xtaran @bikenite Did your shop take pictures of your stuff and share it on social media? (I found out mine did... deeming me their "torture tester" and noting I was a middle aged woman...)

A2: not mine, but years ago on a club run a school friend's (aluminium) handlebars sheared off next to the stem just riding along. He managed to stop safely and was fine (could have been much worse!). Luckily his dad was the ride leader so sorted out getting him home safely.

This must have happened... Maybe 2006. Plus or minus two years. I mean, sure, social media existed, but not to the same degree as today, I think?

@ascentale@sfba.social @xtaran@chaos.social @bikenite@fedigroups.social My former Streetmachine GT (the older steel-framed model) suffered a catastrophic failure of the main frame tube after about 47,000 miles of use. At first I thought there was something wrong with the front tyre - the bike just felt non-specically funny. After stopping several times to investigate and finding nothing, I started off uphill and accordingly gave a harder shove on the pedal to get rolling. Felt the seat move in a weird way, so dismounted and discovered the Crack-of-Doom
while looking for problems with the seat brackets or rear suspension...
Fortunately I was only a couple of miles from home, so got back by walking and carefully rolling down hills. The crack had enlarged to comedy proportions by the time I got back, with the front of the bike wandering in a different direction to the rear. (The break would be in compression while I was astride the bike, but was subject to all sorts of twisting forces while wheeling.)
As the bike was beyond economic repair, with the suspension and drivetrain well worn and coming up for replacement, I bought a shiny new GTe model (sadly at post-Brexit prices), and transplanted most of the accessories. The front boom from the old bike found a home with someone who'd bought a bike from a shorter rider and needed one with a little more extension, so that part of the frame lives on.
