comment Information about an old frame
The cutaways on the lugs are pretty extreme, suggesting this was originally sold as a lightweight bike -- not inexpensive.

comment Information about an old frame
The rear would not have been indexed with downtube shifters.

comment Are 130 BCD chainsets stiffer than 110 BCD?
I doubt that there's a substantial difference, one way or the other. Depends more on the quality of the components than the BCD.

comment What kind of pump/attachment do I need for this? (picture)
That is a bog-standard Schrader valve. If you have a standard chuck for a car valve it will fit. But, since the tire is deflated, you need to press the tire in with your thumb on the back side of the valve to force the valve out while you fit the chuck to it.

comment Sources for vintage or reproduction decals?
Check your local model shop and also any scale model railroad folks you may know. There are services that will produce decals one-off and it's also possible to print them yourself, with the right printer and materials.

comment restoring the finish of an oxidized polished aluminum frame?
Note that the best way to preserve "bare" aluminum is via anodizing, and if the frame was originally anodized then "polishing" it will remove the anodized surface and make the aluminum more subject to corrosion.

comment Is this a collectable bicycle?
It is unusual. Appears to be designed as a semi-folding bike. But the front brake looks a lot like a V-brake, which, if true (and original to the bike), would make it later than about 1995, from what I can find. Looks like its been repainted.

That sounds like a defective hub.

comment Are heavily worn rims safe to use on trainer?
Assuming you're talking about a stand-type trainer and not rollers, the worst case would be the side blowing off and wrapping itself around the seat stays or some such. Would be a "surprise", certainly, and maybe a very slight chance of a wrenched knee or whatever due to the cranks suddenly locking up, but well short of what you'd have with a blowout on the road.

comment Do we really need another bike size?
To make it less confusing and more American-sounding, maybe we should call it "the old Schwinn mountain bike standard".

comment Do we really need another bike size?
@SamuelRussell - Right. But the 27.5 is a 650C. It's just adding another dimension to the confusion. ... Oops! Make that 650B. Confusing enough yet??

comment What are the pros and cons between an aluminium and carbon frame?
If you're concerned about failure, go with steel.

comment What are the pros and cons between an aluminium and carbon frame?
@BrianKnoblauch - Most folks who've tried them say that aluminum is stiffer than steel.

comment Do we really need another bike size?
So the real purpose of the 27.5" wheels is to make use of all the old 700C frame manufacturing facilities?

comment MTB Why are 29ers considered better then the legacy 26'' or 27'' tires?
Which begs the question: What the heck is a 27.5" wheel?? What is the ISO rim size?

comment Why do some people leave the chain sitting on the smaller sprocket when the bike is not used for a while?
I suppose there's the theory that leaving it that way will somehow reduce "wear" on the springs, but, honestly, it doesn't make any difference. Maybe if you were leaving it for a few hundred years, but not for a few days/weeks/months.

Hard plastic or soft, pliable plastic?

Needle and thread. You can buy those and a small piece of "outdoor" fabric at a fabric store.

comment Anti-puncture options
All I know is that I've found punctures virtually nonexistent with Kevlar-belted tires.

comment Anti-puncture options
And I suspect the difference in punctures with the two bikes had more to do with the different tires than the presence of fenders.
