Saxman said:Generally when approaching a hill on my bike, I pedal as far up the hill as
far as I can and then change down through several gears in rapid
succession. Is this the correct procedure? Or should one drop down a
gear before ascending the hill?
Whatever gets you to the top okay...
But ideally you're probably best off maintaining a fairly constant
cadence and dropping a gear each time you need to do so to maintain that
cadence. That should ideally be reasonably quick cadence, as if you're
mashing higher gears at low rates you'll get truly nasty clonking changes.
Quoted message said:It's a bit like comparing gear changes in a car. Should one change down
before a bend or on the bend for optimum performance regardless of safety
factors?
Why not compare gear changes in a car going up a very big hill? It's a
far more direct comparison, and in each case the goal is to keep the
power delivery at the engine's "sweet spot" as much as possible. So you
start off at the right revs for the gear you're in, pile on a bit more
gas to keep them up, but if they start to drop off you drop one gear,
and so on until you either get to the top or run out of gears.
