You haven't said what the frame material is, but if steel obviously yes. Aluminum (and carbon) not so much, but it will add weight. However, in any case it will pose a danger to your bottom bracket. Water will eventually seep past seals and into the bearings, leaving you with a stuck or severely degraded bottom bracket. Your problem could be water ...

I have a trailer for my bicycle... Without the trailer I average 19 mph. The difference between adding the third wheel and 20~40 lbs is about 2~5 mph. Just keep everything lubed and tuned. Also steel frames are more springy/comfortable than aluminium as they absorb more of the bumps etc in the road. The biggest difference is in the rims. Spinning the rims ...

The term for preparing the bottom bracket shell in this manner is called facing, and yes, it is necessary for all outboard bearing bottom brackets for proper function. To understand why this is, lets compare a hollowtech type system to a square taper cartridge. In the square taper, all the bearings and rotating portions are contained into a rigid metal ...

Even if you will have stickers on it, you will not be able to tell what is better quality. Only people who are working on few bikes every day, can notice some problem that is a "brand sickness", and not a 3% defect. The non great brands BMX (i.e. Trek etc.) are always manufactured in china. There are many bike factories, some of them better and some less, so ...

I think you never understand frame condition by smell :). Aluminum and its alloys are great materials, but they could be destroyed by aggressive liquids (salt, acids etc). If I were you Check the lowest frame corners (usually here manufacturers make little holes, to let water out). If you able open it and try to look inside or check by hands. That's ...

Check if Specialized will sell the pin stripe kit. But I would not recommend it. Tape over the old would be difficult and not sure it would stick. Remove the old could damage the bike. I would learn to like white. Consider bright green bar tape, seat post, and saddle.

I'd avoid doing this. Basically, you do a light (typically wet) sanding by hand (very carefully), prime it with an appropriate primer (maybe a few times) and then paint over it with an appropriate color. However, since the sanding has to be done carefully (since its easy to destroy carbon fiber by sanding), you're going to end up paying someone a lot of ...

There are two things at play here: The actual issue of the bottom bracket facing The bike shop doing poor work. With common square taper BBs, you are pretty much looking entirely at problem 2. With a cartridge bearing square taper BB, it's not absolutely necessary that the bottom bracket is perfectly faced. Most decent quality frames, even unfaced, have ...

The last post is correct about two meanings for compact: sloping top tube as one meaning and a compact crank (smaller chainrings) as a second meaning. A third meaning also exists - or used to exist: a bike built around smaller 650C wheels. Cannondale used to market their 650C-wheeled road bikes as compact frames.

It looks like a "Украина". They are quite cheap and also very popular in Bulgaria. My dad had one of those back in the days. I see this has speeds. Shifters are very uncomfortable though...

If you don't chase when you need to, you'll have a very tough time threading the bottom bracket in, and as a result, it may creak or wear out somewhat faster than it would otherwise. The same goes for facing the bottom bracket shell. This is what I would do (and have done) if I were in your position, only for square taper, cartridge bottom brackets*: ...

Looks a lot like an old Free Spirit road. Note the fork crown, the weld quality around the head tube, the attachment of the rear dropouts and the single-piece bottom bracket.

No, usually you don't. That's something that should have been done at the factory. If the threads do need chasing, then you'll have to take it to a shop. The point of chasing is to remove paint over-spray - you can't do that with a toothbrush. A chasing tool probably costs more than a Surly frame, so doing it yourself isn't practical.

The instructions that you quoted are what we call "covering one's ass". Don't let them intimidate you into spending more $ than you need to. Just get a razor blade and scrape it off. You'd have to dig into it pretty hard to cause any problems, especially on a steel frame.
