comment What cassete do I need to run with a compact crankset (50/36), to equal the same gearing as running a standard crankset (53/39) with a 11-28 cassete?
I don't think I've seen too many 10 tooth cassettes. It would probably be too small to fit on the freehub body. 50/11 is faster than 53/12, so you're right it's only that very bottom gear that matters. I think that you really have to analyze how often you are in the 53/11 gear, and if you're really maxing out the RPMs in that gear. I think you could probably go just as fast in both gears, you'd just need to spin slightly faster.

comment Finding Elevation Change, any method
Barometric pressure, can be amazingly accurate. On my GPS, it will give a 1 meter difference between being on the ground, and being held near my belly. It will go up another meter if I hold it above my head. That's pretty accurate as far as I'm concerned. It may give different reading on different days due to weather, but it's hard to beat barometric pressure for measuring changes in altitude over a relatively short period. Also, I haven't noticed the start and end of my rides being at different altitudes, so the change in pressure over the length of a ride doesn't seem to be that big.

comment Most effective upgrades on Road bike
Well, if you are racing, and some change makes you go 0.5 km/h faster, then in a race which lasts 2 hours, you'll be 1 km ahead of a person going your previous speed. So it can make a difference. Although if you're not racing, you probably don't really care about the fact that your 2 hour ride is now 1.5 minutes shorter. You'd probably get the best money from optimizing gearing and working on technique in knowing which gear to be in versus actually actually changing out parts for better ones.

comment How to shoulder a bike?
I think shouldering is meant to be done over 5-10 meters of the trail where it's too hard to bike. If you're shouldering for "a couple of minutes" perhaps you're biking where you'd be much better off hiking in the first place.

comment Are there road bike tires invulnerable to popping?
Since you've already purchased tires, and likely aren't able to return them, you can get something like Mr. Tuffy Tire Liners which are quite cheap, and I've found to be quite effective. Although I haven't had a need to install them since I got some Conti Gatorskins and a proper floor pump(to make it easy to ensure proper air pressure).

comment I have a foreign bike, and don't know what pressure to pump it to
Be careful with "general guidelines" about tire pressures. My gatorskins (700x28) are max rated to 116 psi. The tires that came with my bike, Vittoria, also 700x28 say max pressure 80psi. I had an old road bike that had 25 mm width tires that were only rated to 80 psi, where as most road bikes today will probably be well over 100psi.

comment Data to convince teenager that blinking rear light is worth the “uncool” factor
I think it depends on the conditions. On a bright, sunny, day you'd be lucky if you could even tell if most blinky red lights are on. In foggy weather or dark cloud cover, there would probably be some increased visibility, but I think that using lights while it's sunny it just a little bit over the top.

comment Setting up a bicycle for someone with restricted knee articulation
You could probably get someone with the right tools to cut down a standard crank to the proper length, or just leave it at length and drill a new hole.

comment Hybrid electric bikes, how do they work?
I don't know why nobody makes an electric bike by starting with a road/touring frame. It really is much more efficient to be in the drops. I wonder how much longer battery life would last if the rider was in a more aerodynamic position. Also, it would be nicer once the battery does die to not be on a bike that's inefficient to begin with.

comment Turtles on Trails
Where I live, many species of turtles endangered, to the point where they put up turtle crossing signs, and in some places they've placed culverts under the road for the turtles. The turtles aren't big enough to cause any damage to a car, but they still don't want you running over them. Since they are cold blooded, they are probably on the trail to get some sun and warm up. Moving them off the trail might not help in this situation because they will probably just move right back onto the trail. Also, some turtles have salmonella, so be sure to wash you hands.

comment Bottom bracket cup doesn't fit on non drive side
It's new in box from my local bike store. I realize the threads look a little dirty, but that's just from some of the grease I had on my hands. It's just from their regular stock of replacement bottom brackets, so I don't really see why it would be some oddball size but I guess I'll be taking it back to see if I can get a replacement, or at least a cup that fits, as it seems they definitely shouldn't be different sizes.

comment Bottom bracket cup doesn't fit on non drive side
Correct me if I'm wrong, but just to clarify, on English threads, the drive side is left threaded and the non drive side is right threaded. On Italian, both are right hand threads. Where "right hand threads" is standard threading where turning clockwise tightens the part. Since the bb cup that doesn't fit is on the non drive side, both Italian and English would be right hand threaded on that side.

comment Bottom bracket cup doesn't fit on non drive side
It's definitely English, as the right thread is left hand, and fits in, but I'm beginning to wonder if the left hand cup is Italian, as Sheldon's site says that Italian cups are 36mm, which is slightly bigger than 1.37 inches, which is 34.8 mm.

@DanielRHicks The right cup does not have an unthreaded section. The left cup, does not fit in either side, and the right cup appears as thought it would fit in the left hand side, but it of course won't go in because of the reverse threading.
