Nothing is missing. To adjust these you loosen the pinch bolts on the left crank with a 5mm wrench, use the same 5mm wrench to gently tighten down the large black preload adjusting bolt that's found on the outside of the left crank, and then re-torque the pinch bolts.
This bike appears to be in pretty rusty/unkempt shape. It would be a good idea to at ...

OK, I eventually worked out the easier way.
The locknut has a hole in the end which, in addition to taking the skewer when fitted, has a hex socket for a 5mm allen key. Turn the hex/allen key anti-clockwise relative to the cone spanner to undo.

There's lots you can do if you want! The best maintenance is this: keep it inside a heated area whenever it's not being used. Use it often.
Keeping it inside is obvious: out of the elements is important for anything mechanical.
The worst bikes I saw were ones that had been abandoned outside for long periods of time. Not using the bike allows everything ...

You are totally right! There is no one perfect way to lube your bike. Few days ago a cleaned the chain with gasoline and a soft metal brush (there's a cheap kit at Harbor Freight) I use half plastic container of orange juice to hold the gas and the dripping dirt. Once dried I lube with some synthetic oil left for my electric generator (10-30 Pennzoil) I ...

You need a 3/8"x26tpi (threads per inch) axle nut. For decades they've all had 15mm wrench flats. (I believe that is something where you can find other examples in very old American, British, and probably other inch country bikes, but that is here nor there.) Bike shops have them.
3/8x24 is usually only for internally geared and coaster brake axles. ...

This question came up recently in Lennard Zinn's Technical Q&A column. Apparently if you leave a part in Simple Green (the degreaser he specifically discussed) for a very long time, the metal can deteriorate. But this is a matter of weeks or months. If you rinse off your chain the same day, it won't be a problem.

The ones available around here , at least, seem to be generally less effective than the bike ones on a per-unit-volume basis, so you might need to use a bit more, but it certainly shouldn't do any damage (which would tend to result from them being too strong).

Had this so so many times and so far it’s always came down to the mech hanger being slightly bent, delivering the chain to the cassette slightly off causing it to be exaggerated under pressure. Spent over 400 trying to fix it, then as a last resort just by chance changed the mech hanger (30 euro), it was SLIGHTLY bent like a few millimeters and that’s what ...
