Out of curiosity I googled the reviewers name, and lo! 6 months earlier he had been writing for a model railway magazine. Never bothered buying a bike magazine since that day.
Go away. You are making me feel sick.
Interesting.... most (modern) lights are modulated at several kilohertz, but I guess it's difficult (or at least expensive) to filter out the mains frequencies entirely.On the turbo last week I got bored of staring at the garage walls and noticed that the chain on the front chainring appeared to be stationary. 50 tooth chainring, 50Hz mains frequency therefore exactly 60 rpm. I dropped a few gears and spun it up until it appeared stationary again, so 120 rpm but I couldn't comfortably maintain that for long.

It will be exactly one link movement in 1/50th second, or 2 links worth, or 3... so a 50-tooth chainring worth in one second, or half a second, or a third of a second... hence 60 rpm, 120 rpm, 180 rpm...hmm, Hz is cycles per second , whilst rpm is revolutions per minute. You’ll have to explain the maths of your reasoning here.
I hear ya.Narrow tyres are better.
Wider tyres are better.
Tubs roll better than clinchers.
Clinchers roll better than tubs.
We all want to go faster and easier and we are all crap at it when we first set out.I'm inclined to think there's an optimal torque output for each rider, and you tend to subconsciously vary your cadence in order to maintain a fairly consistent loading on your legs.
