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.

comment Bottom bracket cup doesn't fit on non drive side
@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.

comment Bottom bracket cup doesn't fit on non drive side
I can't even fit it up to where the threads engage. There's a short (1/4 inch?) non threaded part, which, just barely, doesn't fit in to the bike. Also, the bottom bracket has cups on both sides, which is different from this video where they state the drive side should be permanently affixed.

comment How do you distinguish a touring bike from a speed/road bike?
Touring bikes will also often have Cantilever or V-Brakes, as most (all?) caliper brakes cannot work with fenders.

comment What type of tires have tubes inside?
The GMC Denalli is avialable at Walmart, and I am therefore 120% sure it's using clinchers.

comment How to clean a combination bike lock?
It's probably just from the sugar, so you'll want something that will dissolve the sugar, like warm water. Add some WD-40 to get rid of the water after it starts moving again.

comment How much do components really matter for a non-competitive rider?
Yeah, I think that road bike have a little problem where even the "lower end" stuff has a 10 speed cassette, where they probably could have delivered a much better component for the same price by going with an 8 speed cassette. Most people buying lower end bikes would probably appreciate the added durability and not needing to have the bike in such good tune at the expense of having a little more spacing between the gears. It's much more common to see 8 speed cassettes on mountain bikes, even though they probably have more gear range within the cassette.

comment How much do components really matter for a non-competitive rider?
My first bike I purchased as an adult had an Acera rear derailleur and similar quality components on the rest of the bike. After 15,000 km riding in all kinds of weather, I probably needed a new cassette and a new chain, but never bothered to replace either because I was ready for a new bike anyway. Only think I replaced on that bike was tires and brake pads. I now have a better bike, and I do feel the difference in how smooth the shifting is, but I'm not convinced it will last any longer than the cheaper components.

comment How to choose the right Citi Bike?
They could really save themselves a bit of trouble if they would put a pump at the docking station. If the tires aren't inflated properly, the tires are going to wear out faster, and the wheels may undergo additional strain if the pressure is too low as well. Flats can be more frequent, and there can also be a danger of the wheel coming off the rim if there is not sufficient air pressure. The pump, assuming people used it, would more than cover the cost of incidental problems caused by improperly inflated tires.

comment What is the benefit of a larger disc rotor?
A larger rotor should also provide more braking power by the fact that it's further away from the axle. Assuming an equal braking force, at a longer distance, it will put more torque on the wheel, which means shorter stopping distance.

comment Should the bike or the rider take the jolt from a bump, and how?
To elaborate, you should shift your weight back as your front wheel travels over the bump, and shift your weight forward as your back wheel travels over the bump.

comment I shortened my chain, is this bad?
It is technically possible to get the pin back in even if it has been removed completely. I speak from experience.

comment How can I find the right size road bike without a test ride?
I guess that's one advantage of going with a big name like Trek. They do enough volume that they can afford to make very small size increments in their sizes, and still sell lots of each. Compare that to a smaller manufacturer, like the one I bought my last bike from, and the difference between the one I bought, and one size smaller was very noticeable, even after only 1 minute of riding. I could see how some riders would fall in between the 2 sizes and wouldn't be comfortable on either size.
