comment What's the farthest you've travelled on a fixed gear?
sounds kind of like it fits into the category of "there is no actual problem to be solved". how far you could go on a fixed gear really just depends on your physical prowess and determination. The original TdF racers had fixies, went over 400km in a stage, and had much worse roads than we have today.

comment When do I need more than one bike? How many bike is enough? How many bikes is too many?
It depends on the kind of riding you are doing. Personally I would go for a proper road race bike, then a cyclocross bike for commuting and light trails, and a beater for winter and going places where bike may be susceptible to theft. I don't go on trials that require a real mountain bike.

comment I want to weld or braze the pedal to the crank arm, but what metals are they?
depending on the type of crank arm, it might be easier to find a used replacement. can you get a picture of the other end of the crank arm? If it's something common, it should be easy to find a part. You could probably salvage one off a bike that's no longer usable because of some other unrelated problem.

comment Annual technology gap of high end road bikes
It's worth noting that The UCI rules article 1.3.007 states that all parts must be commercially available. So by having Di2 used in the tour in 2009, it would have to be available commercially that same year or before. I think that's part of the reason you see these $15,000 bikes for sale. A bike isn't race legal unless it's sold commercially. If there wasn't that requirement, you probably wouldn't see manufacturers trying to sell these bikes. Just like you can't buy an F1 or NASCAR car.

comment Annual technology gap of high end road bikes
I think it's really hard to define "high-end". Some might say a Corvette is high-end even though you can get one for $60K. Meanwhile, a Ferrari Testarossa costs around $220,000, and there are other super cars that cost over $1,000,000. A $2000 bike it still quite a high performance bike. The amount of advantage you'd get from a $10,000 bike compared to a $2000 is really only something you'd notice at a highly competitive level. The biggest difference you'd notice is the drain on your bank account, both at purchase time, and when you need replacement parts.

The point is, is that they will always want to sell a $5000+ bike. But if they start putting electronic shifters on a $2000 bike, what reason is there to spend $5000? If there is no discernible difference between the components why spend more. The point is, as we both agree that electronic shifters are a long way off for $2000 bikes. But our reasoning for that conclusion differs. You say its because of the high cost of the components, while I say it's because they are creating artificial scarcity with high prices to create bikes which cost thousands of dollars in order to make a lot of money.

Some guy mode homebuilt electronic shifters of electronic shifters for around $155. They aren't quite as nice as the factory built units, but they still did the job. If you do a parts breakdown, there's a some wires, a microcontroller, some batteries, and a few other cheap electronic parts. You could bring the costs down quite a bit if you were buying components by the thousands. Most likely it only costs Shimano less than $200 to make an electronic DuraAce as compared to a mechanical one.

Probably never, or once they've abandoned mechanical shifters altogether. There's nothing inherently expensive about them. Maybe once they cost $1000 bought seperately. But then the same level of mechanical shifters would have to cost less, maybe around $500. But at that price, you'd start to see DuraAce\Ultegra on $1000 bikes, which they really don't want either. They want electronic shifters and DuraAce/Ultegra components to be expensive, how else do you convince people to spend $5000 on a bike. They won't abandon mechanical because some people will refuse to have batteries on shifters.

As far as electronic shifting goes, the price is kept artificially high. There is nothing inherently expensive about the components necessary to create electronic shifters. Some parts actually become simpler, as the brake lever can go back to the old style of being just an actual brake lever and only need to move along 1 axis. Maybe once Shimano's patents on electronic shifters run out you'll see them lower their prices.

If you are just doing this for "fitness/fun" why not pick a different route that doesn't have 15% climbs on it until you get into better shape?

comment Clipless pedals: Why clipping in so darn difficult?
@PeteH As long as the contact area is rigid and doesn't flex, the size shouldn't matter. I guess the larger platform spreads the pressure out over a larger area on sole of the shoe, but unless the sole is flexing and therefore not distributing the pressure evenly over your foot, making things uncomfortable, then you could have a problem. But if the shoe is sufficiently rigid, this won't happen. You could step on a nail, and as long as it doesn't go through the sole the pressure on your foot would be distributed the same as if you were standing on solid ground.

comment Clipless pedals: Why clipping in so darn difficult?
My SPD Pedals are clip on one side, platform on the other. They are weighted such that the clip is usually up. So they clip in quite easily. In the event that they aren't oriented correctly, the platform works well enough that I can pedal and then clip in once I get up to speed. Also don't confuse the rule 34 above with the NSFW Rule 34.

comment Should tyre sidewalls appear cracked so quickly?
As a point of reference, I use a good floor pump with a pressure gauge, and always keep the tires near the recommended inflation (80 psi on 700x32) and I still get cracks similar to shown in Fig. 1 in the link, although I don't use Schwalbe tires.

comment Could you make a bike frame out of 24kt gold?
You'd run into tons of problems because the material is so soft. Just think about attaching a wheel to a solid gold fork. Even the pressure from tightening the axle bolts or quick release would deform "drop-outs". Even if they were oversized with extra long bolts to compensate for the added thickness, the bolts would still work themselves loose in no time.
