Well I'm very surprised to hear that.Extra pull is a controversial topic.
Research by one of the pro teams - I think it was Sky - found the extra pull on the upstroke is minimal.
If you think about it, you won't have much upward power in your leg when the other one is pushing down hard and your body is not wedged anywhere, it is just astride a bicycle.
Off the bike, stamping (and kicking) is where the leg strength is, not lifting...........
Many riders feel better connected to the bike when clipped in, which in turn makes it feel like they are pedalling more efficiently.Well I'm very surprised to hear that.
I've always found pedalling felt more efficient with either toeclips or cleats. I have several bikes that I regularly use, and haven't fitted cleats or toeclips to three of them, and I never seem to get so much power into those, especially on hills.
They make a really big difference on my recumbent trike, as you can't stand on the pedals with that one at all. Leaning back in the seat, it definitely feels like a strong push-pull effort with the cleats.
Not so with my shoes alone but yes yes yes with neoprene socks.Returning with toasty warm dry feet has been a lovely experience
When you said "the all-important factor", I though you was going to include the far greater efficiency of recumbents.........Recumbents are very different, being wedged into a seat with a backrest makes all the difference, particularly when pushing.
Incidentally, when I volunteered at London Edinburgh London, the first British rider to reach Barnard Castle in County Durham was on a recumbent.
He was fifth, only about 20 minutes behind a mixed group of Dutch and Germans - they all left the control together.
It goes to show the all-important factor way above anything else is the engine - the rider on an unpowered bike.
You could put that recumbent rider on a Penny Farthing and he'd still be ruddy quick.......
I can imagine the extra pull on the upstroke could be minimal in the sort of situation the team was reviewing - endurance and climbing. However it's certainly not the case for sprinting away from the lights, when the body is producing the greatest torque in the crank arms.Extra pull is a controversial topic.

Your body isn't wedged anywhere but it is the upward pull on the rising crank that pulls your body down and also enables you to put more pressure on the downward crank. The maximum force exerted without doing this is of course your full bodyweight on the downward pedal, so 137Nm for an 80kg rider on 175mm cranks at 3 o'clock (crank position, not just after lunch). However if for a very few seconds you are pulling the equivalent of 10kg up you can push down with 90kg, which both totted up give you 172Nm of torque. A significant step up. It's why your arms get tired - they are fighting the rotational effect of one side pulling up and the other pushing down.If you think about it, you won't have much upward power in your leg when the other one is pushing down hard and your body is not wedged anywhere, it is just astride a bicycle.
For a tenner I'd recomend neoprene fishing socks, after all those blokes stand around all day in freezing waterNow it's cold, I have gone back to wearing my boots & two pairs of socks. And my feet are still freezing.
They're great those boots - wore them all last Winter and still in very good nick. Wish I had time to ride more this year - every time I think I'm going to get out there I'm either hijacked with work, have to take the dog out or go get supplies ! Looking forward to next Spring when I may finally get a day or two off !seeing your shoes Gringo, I have just bought these puppies in the CR sale.
And after the first ride.
Returning with toasty warm dry feet has been a lovely experience.
