    Hmmm. So you don't know the context but are willing to decide that it "doesn't say much for Wiggins"?

    Here's the context: Bradley Wiggins re-confirms that he wants a Giro/Tour double

    That was...

    Yeah. I've never used Q-rings but a couple of years ago I rode a borrowed bike for several weeks with Osymmetric rings, which are the same idea. Several years ago I had a bike with Biopace rings, so...

    The puzzle is that while in the lab they appear to enhance power (for example, O'Hara 2012, which you can get from the Rotor website), in the real world they don't seem to...

    Comparisons of power across (aerobic) sports shows that the correlation is high but it certainly isn't 1. It's the same heart and circulatory system but the specific movements and muscles involved...

    When and if you hear back, please let us know what they say. In general I'm not a huge fan of cadence-specific workouts unless they have a specific context and specific goal. They can, occasionally,...

    Your old speed sensor probably has a reed switch in it. Reed switches have to close and then re-open by the time the magnet rolls around again, so there's typically a minimum amount of time between...
