The pedals look more like Cyclone (or the MKS analog to Cyclone pedals) than Superbe. But still, for $20 it's hard to go wrong.

Campagnolo type bosses are 5mm x 0.8mm thread; some Shimano bosses are 4.5mm x 0.75mm thread. I doubt you could retap a 4.75 x 0.75 boss to 5 x 0.8 without problems. Shimano did make a conversion kit...

It is possible that the wheel is not properly dished or the frame is out of alignment. If you put the wheel in the frame backwards (cogs on the non-drive side), is the offset still there (same...

Of all the front wheel retention devices out there, those Schwinn tabs are probably the best. All the other ones require unscrewing the quick release significantly to get past the...

I was Trek's warranty inspector back when they made lugged steel and bonded aluminum frames. Rust under the paint is obvious from the bubbling, and not a warranty issue. Even rusty steel frames...

The nice thing about SunTour derailleurs is that they all perform pretty much the same, and that performance is uniformly excellent. The fancier models will be lighter and better finished, but don't...

And so-called 27.5" are just 650B. What's wrong with people?

It would be so much easier if everybody used the ETRTO size designations.

The rim shouldn't be a problem. The larger concern is frame clearance, as dsbrantjr noted above.

This is particularly a problem with new bikes, where the paint may not have had time to fully harden. Like you, I always clamp on the seat post or the Park ISC-1 internal seat tube clamp.
