comment Annual technology gap of high end road bikes
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.

comment What's the lowest safe cadence on a climb?
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.

comment Could you make a bike frame out of 24kt gold?
Probably make much more sense to make a steel frame and gold plate it. Even if you could make the tubing large enough to support the weight of the rider, it would still be quite soft and easy to dent. Also, assuming the frame weighed a mere 5 kg, which would bring the total build weight close to the UCI weight limit of 6.8 kg, it would cost over $200,000 just for the gold alone at today's gold prices.

comment Theft deterrents (in addition to locking up a bike)
One thing that needs clarification is this "high number of stolen bicycles, as much as 50%, were fly-parked". It doesn't say what percentage of bikes in the study were "fly-parked". If 50% of the bikes were parked this way, then fly-parking wouldn't really increase your chances of having your bike stolen. Or if there tended to not be adequate bike racks in high crime areas, then the theft may have been more due to the fact that was parked in an high crime area, and not because of the structure the bike was locked to.

@Aushiker Yep, looks like prefilled tubes are still sold.

comment “Quick Fix” Tyre Repair Spray Cans
"Wouldn't be suitable for some punctures". This is the key right here. If you have a complete blowout, this isn't going to help. You won't know it's a blowout unless you take the time to remove the tube and inspect it, and by that time, it's easier just to replace the tube. If you don't inspect it, and it is a blowout, this product would probably cause a huge mess.

comment Analysis of Stages high-speed data
Wattage is define as Joules Per Second, or Nm / seconds. Since you have a value for Nm, and the timestamp, you should be able to calculate the wattage. The angle or speed of the crank arm doesn't come into the equation. Your wattage will vary throughout the pedal stroke, as you are less efficient at various positions through the pedal stroke. At least I think this is the way it works. Somebody feel free to correct me.
