Was once told my bike was a "three-speed with five gears." Now posting actual bike repair #BR tidbits here on bsky instead of that other place.

I was never a fan of this style seatpost. #BR Those are only M5 bolts. Factor that with cheesy materials, manufacture, and inexperienced assembly, and-POOF. Sometimes you get a lot of sticktion on the threads, rendering torque specs useless. Sometimes, mechanics don't draw up the bolts evenly.

If bikes ruined by rust skeevs you out, look away. #BR The wheels on this bike had many spokes broken or missing. I first thought someone had cut the spokes, but I believe they simply snapped under their own tension. The corrosion was so bad that I could crumble the spokes between my fingers!

What is this nonsense? #BR I think this thing on the handlebar came with the bike as part of some theme--but it didn't age well.

This is just careless. #BR Incorrectly installed rim strips can cause time-wasting, annoying, "mystery" flats. It's infuriating that both these botched wheels were from the SAME bicycle!

Is the steel ratchet-style saddle clamp the most misunderstood bicycle component? #BR While inspecting a kid's bike for correct assembly, I found the usual mis-engaged teeth in the saddle clamp. However, I was not expecting that the clamp itself was barely hanging on to the seat post! 😱

I often find bikes with these saddle clamps tightened using only one of the two nuts, but this one just shows a bad assembly job. #BR One nut is barely engaged, while the other is threaded on too far. A nut that doesn't fully engage its mating thread may give way suddenly, leading to an accident.

So little of the nut is engaged by the stud that the internal thread on the nut is visible.A view of a steel ratchet-style saddle clamp, showing the fastening nut threaded too far on to the stud.

I'm still finding bikes with kickstands "installed" using the Lazy Mechanics method. #BR Pletscher end Greenfield alloy kickstands should be trimmed to size before installation.

Here's a brake shoe I found installed #Backwards, or upside-down. #BR The little arrow is a hint, but the more obvious clue is that the curve of the shoe doesn't follow the curve of the rim. Could mechanics be a little more observant?
A front cantilever brake with a brake shoe installed upside-down: the guide arrow on the shoe should point forward.

This particular shoe is curved, so its curve should follow the curve of the rim. Note how the rearward corner of the pad is nearly touching the tire because the shoe is upside-down.

Please assemble hardware in the correct orientation! #BR This pronged safety washer was installed #Backwards, defeating its purpose. This safety feature is important because it will buy you some time in the event the bike is ridden with the nut loose.
Close-up of the axle nut on the front wheel of a child's bike. The washer with a prong that normally engages a hole in the fork is turned the other way--the washer was put on backwards. This safety feature is important because it will buy you some time in the event the bike is ridden with the nut loose.

I opted to screw the pedal in from the backside of the crank arm, where the threads were still intact. The good threads act as a pilot, allowing the pedal thread to act as a thread chaser to (somewhat) straighten the damage. #BR Note: I would NOT use this technique with alloy cranks!
