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.

Q2. What _unexpected_ part failures have you had on your cycle(s)? (Ordinary flat tires do not count.

@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.

@geonz @ascentale @xtaran @bikenite
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.

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
@ascentale @xtaran @bikenite@cpm @ascentale @xtaran @bikenite Yeah, he had a bad batch of pinion gears. The HPV forums had a couple of other people with the problem. But 'normal' people were fine, it was folk like me, and tandem riders, that broke them.
I still wonder whether he just under-specced them and discovered that 1% of users were stronger than expected.

@etp@indieweb.social @ascentale@sfba.social @xtaran@chaos.social @bikenite@fedigroups.social Tightening by feel is probably fine as long as you don't have carbon material to deal with.

@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. -
@the5thColumnist That looks like it could actually work, especially on slightly loose packed snowy roads
Wonder how long they stay on though, seems to be missing one already.

It was for a race on a frozen pond and it didn't work.

@moz @cpm @ascentale @bikenite: Funny that SchumpfDrives come up in this thread. Got one, too, and it's still working fine. It's though a rather new, Kwiggle built one. Florian still builds one type himself: Those for unicycles. Met him at last year's SPEZI (special bike fair in Germany).

@the5thColumnist @eq @ascentale @xtaran @bikenite This is close to what I did.
FWIW Schwalbe has a studded snow tire for under $60 (each) and unless you're really strapped for funds I think that's a better deal than a DIY. I particularly think Nokians with carbide studs, even though they're more expensive than my car's tires, are worth every penny. They last forever and don't wreck your tubes.
(I bet a DIY with tubeless tires and extra sealant would work well, though.) -
@the5thColumnist @smellsofbikes @eq @ascentale @bikenite: Those spokes look odd, too.
@xtaran @the5thColumnist @eq @ascentale @bikenite Spokes are a fancy wrap job: halfway out, twist around adjacent spoke, then back to a different hole than where they'd usually go. These fail quickly in use in my experience but they sure look cool. (Tie-and-solder spokes are *good* but a pita to replace when you break one.)
