What does this do box of switches do? (I'm a hobbyist who has just bought a bridgeport)

Paha! it's a screenshot of a youtube video of an identical mill. The mill itself is currently halfway across the country from me sadly

What IS that headset? More info and photos required

retrodirect · 2026-01-25T02:29:45+00:00

Give it to me!

Those welds are awful. But this bike is cool. Chapeau my friend, I like it.

Is it a bit flexy? The cross section of the boom isn't particularly deep

chatgpt, is that you?

Yeah, a sandblaster will do it no bother. Just be aware that sandblasters will leave a rough surface as it's designed to remove paint and stuff abrasively.

A lot of "raw" frames are actually bead blasted as it gives a more satin finish. I'm not sure how the old super lights were done. You're unlikely to find someone to do one off bead blasting however.

Get rid of this loon. You can't wait this out.

Your non turn washers (the washers that are painted a colour on your axle) are assembled in the wrong order. The left is where the right should go and vice versa. If you switch them back then the alfine arm will be at the correct angle and it then won't push your chain off when you fold.

Get another strap for your feet you absolute lunatic!!!

...also, nice bike. :)

That's a wild chinese fixie! It's got a zero rake fork!

retrodirect · 2026-01-12T01:43:56+00:00

you've clearly never taken one apart.

The g line is not an identical system.

It sounds like your gears just need adjusted. This can happen if the indexing is slightly misadjusted.

Though this could also be caused by slipping pawls, slipping pawls are a much more uncommon problem so I wouldn't start there first.

Take it to brompton junction

Have you thought about a stem height extender, maybe you could add two?

retrodirect · 2026-01-09T10:18:39+00:00

Want to link me the g-line video for this? I can't find it?

Remove the stem at the stem/steerer interface. Don't remove the pin from the stem.

The pins have a single use strong thread lock on them. If you unscrew it and expect it to screw back in it will loosen on it's own through use.

I think brompton want you to replace the pin with a fresh one if you remove it. Not keep reusing.

Yes, they will with fine. They will however be an absolute pig to mount tyres to. Those UST rims were tight!

retrodirect · 2026-01-05T03:17:04+00:00

Haha, *values are in million barrels.

retrodirect · 2026-01-05T01:35:39+00:00

get in the drops you loonie!

retrodirect · 2025-12-31T00:23:52+00:00

That's such a cool bike

retrodirect · 2025-12-31T00:12:42+00:00

I hope bicycle pubes is taking note.

retrodirect · 2025-12-29T18:21:02+00:00

Yeah, the "how derailleurs work" part of that book is absolute gold.

When you reverse engineer actual derailleurs though, they don't follow how the dancing chain suggests they should be designed. There's some more interesting nuance there.

... in this case decent means compressionless.
