    I'm not really familiar with the area (drove through Bridgeport once and rode between Bishop and Mono Lake a few times) but I think you need to clarify. Are you going to go camping there some time...

    You are correct about heat conductivity. However, in a moderately deep carbon tubular rim, the area under brake pads and contact points with the tire account for something like half of the mass...

    Presumably, the intended use of the light is blinking/flashing mode. Steady mode is there if you really want it but the light is not designed around it. Hence the tiny battery.

    The physics of it is pretty straightforward.

    Braking turns your kinetic energy into heat. All else equal, when stopping from the same initial speed, a 80-100 g road disk is going to heat up to a...

    I don't see how you can snap a seat post while riding on the trainer. Also, I don't think he was even pedaling when this happened (or if he was, he stopped immediately) - note the blood pattern on...

    Good point. In my experience, even 18% presents major difficulties: if you stop for whatever reason, it's all but impossible to get going again. At these grades, wheels don't offer much of an...

    If it's Spain, 30% grades are not totally out of the question. They probably still have lots of roads which were originally laid by Romans and designed with donkeys in mind.

    These grades are very unusual. Around here I know a couple of private roads that go to 15%, but U.S. road construction standards generally prohibit going above 12% on public roads and require even...

    Agreed about the fluke. In fact, the plateau should extend with relatively little loss of power from 1 second to 20 seconds or so. One other observation is that the curve probably underestimates true...

    Running a deep spline cassette on a shallow spline hub is not a problem. CS-6700 would work fine with either a shallow spline or a deep spline hub. (The reverse is not true: a shallow spline cassette...

    Hubs account for part of the porkiness. The ones in LVWA's are clearly Novatec A271/F372 and they weigh ~385g/pair. So, excess 100 g in the hubs and 100-150 g in the rims or elsewhere. (Enve's 60 mm...

    60 mm clinchers are inherently not feather-light. These also look about 100-150 g heavier than typical for a pair of Chinese carbon wheels. Working back from their declared weights (assuming A271...

    One year and over 3000 miles on their 50 mm wide tubular road rims. No issues. Not sure if I'd risk their clinchers, but tubular rims in general are simple in construction and hard to screw up.
