comment Magnetic trainer failure
Other trainers do a better job at limiting the maximum speed. Looking at the numbers here, you'll see that many trainers increase the resistance linearly with speed, which means it would be quite easy to go overspeed, while others look to increase exponentially with speed, which would very much limit the maximum speed you could obtain.

comment Can I change chainring size on a dirt jump bike?
I'll give you the clearance factor, which is important on a BMX, but according to the article, the weight savings is negligible, and completely overshadowed by the savings in chain friction.

comment Do Miche bottom brackets require a special tool, or is this one damaged?
Could be a manufacturing defect. Take it back to the store and have them compare it with other bottom brackets from the same manufacturer. I bought an English bottom bracket last year where the drive side cup was Italian sized, and was therefore too big to fit in. Turns out they got a whole batch of bottom brackets with the same problem. They were able to give me a properly sized bottom bracket once they found a box with that had a correctly sized one in it. I'm sure the shop wouldn't mind helping you out on this, as long as you are polite and try no to make it seem like it's their fault.

comment Can I change chainring size on a dirt jump bike?
Yeah, reading up on it, you can get 8 tooth cogs for BMX bikes, which pretty much makes up for the difference in tire size between a road bike (where the smallest cog is 11 tooth) and a BMX. However it's important to note that using large gears is more efficient than using small gears, even if they end up at the same ratio.

comment Have you built your own components?
Making bikes out of wood (in whole in in part) seems to be a big thing lately. Personally, I don't see them as desirable, but there's a lot of people doing it. Google around for wood bikes and you'll probably find plenty of inspiration.

comment how to adjust the derailer - apart from the L/H limiting screws
Gear cables should last longer than a year. My first adult bike had over 12000 km on it before I retired it, never once needed to change gear cables, and I rode it in all kinds of weather. Might be more needed on a mountain bike that gets a lot of dirt on it, but you should get quite a bit of mileage out of them.

comment Modifying Brake Cable to Fit?
My vice grips have a small cutter on the innermost part of the jaw. Set the vice grips to the smallest setting, and they work great for cutting brake cables.

comment If a lane is going to expand should the left lane be taken prior to the expansion?
I really agree with this. I see too many cyclists get all in a huff that cars wouldn't let them in, and they were unable to make a left turn. Some times it's just easier to just bike/walk straight through, and then set yourself up to go straight when the light changes. It might take an extra minute while you wait for the light to change, but in some instances it might even be quicker. If the advanced left green has already finished, you often still have time too go straight through, in time to adjust your positioning so you can go straight on in the other direction.

comment why does the lemond revolution turbo trainer quote its volume of air resistance in meter^2 and not per second cubed?
m/s^2 is the base unit for acceleration, so perhaps it is because the resistance (measured in newtons), varies as a function of the acceleration which you put into the pedals/trainer.

comment Bottom bracket removal, what is this part?
There are also more desctructive ways of removing it if you are just replacing, and you can't find other methods to get it out.

comment Backpack size - 10L vs 14L
Can't speak about those packs specifically, but I find that you really have to hold a pack in your hands to know how big it is, and preferably try to pack the things you want to pack. Some have many small compartments making things easier to find and to stop things from jostling around, but harder to fit in large items. Other packs are the opposite where you have 1 large pocket which allows you to pack large items, but everything gets lost inside.

comment Why do some triathlon seatposts go straight up and down instead of at an angle?
There's a difference between your animated gif and the pictures the OP posted. In your gif, it seems like the seat post (and resulting seat position) is actually quite far forward, whereas in the question, it seems like the seat ends up in more or less the same location on both bikes. It seems like in the question, the bike has been designed to optimize for air flow, while still putting the seat in the same place.

comment Best 9 speed cassette for fast & flat
You might want to go with a cassette with very fine spacing, like a 12-23, and then change your front chainring for a smaller one so that it's the equal to having a 15 on the back with the chainring you have now.

comment Knowing what bicycle frame material I have
The sad state of affairs is that cheap department store bikes often have large tubes and are made of "steel". Presumably this is because the steel is such low grade that they require large tubes, or because the manufacturer thought it would make the bike "look cool". The result of this is that my kids have BMX style bikes with 16 inch wheels that close to as much as my old full size road bike which is also made of steel.

comment Cyclocross Rim Wearing with Rim Brakes and appropriate Solutions
Option 1 and 2 both require new equipment. If you're going to buy new equipment, you could also replace the front fork and hub and install a disk brake. At least that's one less rim to worry about wearing down.

comment Sheldon Brown's writing?
@CareyGregory While some of it is still being updated, some of it has fallen out of date. For instance, looking at the tire sizing page, it says nothing about 650b size tires now being somewhat popular on mountain bikes, only that it was used on "some older Raleigh and Schwinn mountain bikes". His pages also say very little about 11 speed cassettes, even though they are becoming more popular, and probably aren't going to disappear. Those are just a couple small examples, but I'm sure there's many more instances.

comment Sheldon Brown's writing?
I think the only problem I have with his content is that in some ways it has become a bit dated. Is there any chance that his stuff could be turned into a wiki so that it could continue to be updated?

comment Can a road bike be transformed intto an mountain bike?
With the right skills you could transform a car engine into a mountain bike frame. Trying to get a full suspension mountain bike out of a, hopefully steel, road bike frame would probably be quite difficult even for an accomplished frame builder.

comment Specialized bike store or general sports shop
Very much agree with this. I wouldn't hesitate to buy a bike from MEC, even though they aren't technically a bike shop. I've actually received much better advice here than at some of my local dedicated bike stores.

comment What do you wish someone had told you before your first commute?
@arne there's still places to change at university. Most likely more than at the office as most universities will have a gym with a change room and showers. Membership is probably included with tuition, but even if it's not, you could probably get friendly with the students working the gym and they'll let you use the changerooms without a membership.
