comment Are 28 / 47 - 622 / 635 tubes ok to replace my 28 / 44 - 622 ones?
The "28 / 47" is the range of tire widths the tube can accommodate. 37 is right in the middle, which is ideal. Manufacturers tend to "stretch" the numbers a bit, and so you'd want to avoid, say, a 22/37 tube if the 28/47 is available.

comment can a single sprocket be locked on a road bike?
Sorry, your question doesn't make a lot of sense. I'm aware of no multi-speed options that don't essentially require freewheeling.

comment Saddle Rail Failure?
Saddle rails can fail. I've seen it on exercise bikes at our gym, which is not exactly a "punishing" environment. What's often not appreciated is that the rails are hollow tubes, not solid bars, and thus they can fatigue fairly easily, especially if overloaded.

comment How do I tell if my cog needs replacing?
It's definitely worn, and there is some barely-perceptible hooking. But it's probably fine, with a new chain.

comment Lubricating screw/braze-on threads: Bike lube or polylube?
Looking at the specs, the Polylube is probably slightly better. The ProLink chain lube sounds to be a bit on the "dry" side.

comment Lubricating screw/braze-on threads: Bike lube or polylube?
Odd, I never (well, hardly ever) lube rack/fender/water bottle screws, and have never had any trouble. Of course, I always use SS screws. But, to answer your question, any lube that forms a coating and won't easily wash off should be fine.

comment Cold weather chain lube?
@PeteH - Yeah, I'd generally recommend a "wet" lube for winter, so long as conditions aren't dusty.

comment Employer Duty of Care for cyclist
I think in most of the US there would be only a minimal obligation to protect people from serious risk of bodily harm -- more an insurance thing than a legal obligation.

It would be a bit easier to tell the shape of the cog if we had a straight-on picture.

comment Cold weather chain lube?
A PTFE lube consists of PTFE particles and a "vehicle". The vehicle is unimportant as a lubricant, it's the PTFE that does the job. So shouldn't be a problem, so long as the stuff's fluid when you apply it. But most other lubes will work fine too.

comment Why are there almost no bikes with a single chainring?
@PeteH - I forget what it was called, but "Arena" doesn't ring a bell. Would have been 1972.

comment How can I properly replace the hose on this older Schwinn pump?
Take it to a hardware store (when they're not busy) and see if they have a bolt or fitting that matches. With any luck it's IPS.

You could check with a local outfit that fabs hydraulic and air hoses for industrial purposes.

answered Apart from the size, is there any difference between chains for derailleurs or for single-speed / internally geared hubs?

comment Shorten or replace bicycle chain?
Yes, it's actually a bit late to be replacing the chain -- there may be problems due to hooking on the cogs.
