it’s is a component of power. torque x RPM. so obviously your power meter generates a value for it. we had a 160-post discussion about this 2 or 3 years ago. i believe i held the unschooled minority view.

If I recall, and paraphrasing Andy C, it can be summarized as “just press down hard, stupid”.

In the same vein, if I remember correctly, Jim Martin tells a story of a top level cyclist he knew saying that he “just imagined crushing the skull of his competition under his foot” when asked what he thought about in regards to pedaling technique.

It’s as if Jim Martin and Andy Coggan know each other :wink:

Thank you for the link. I’m definitely in your camp and find it interesting

Reading about nitpicking between angular velocity and vector velocity or whatever was painful. Holy moly. I was reading like my english books: page 1, and then backwards. and couldn’t get past page 6.

Back up a second. What is torque efficiency?

Is that like finding the torque that’s in your wheelhouse for metabolic efficiency? (sort of like finding the cadence that has the lowest metabolic cost for a given power output).

We won’t know what he means until he explains it, since it could be one of several things.

He could be referring to metabolic efficiency based on balancing torque and cadence, as mentioned above.

I have a feeling he is referring to pedaling smoothness, though. You can push down hard on one pedal but lose efficiency on the top, bottom, and rear of the stroke. If you aren’t lifting the weight off the recovering leg, for example, some of the torque exerted by the downstroke leg will be negated.

C’mon. He’s clearly just trolling LS.

Yeah, but that other leg needs to move back up regardless and it’s quite possibly more efficient to push it up with the downstroke leg than to ask the recovering leg to pull itself up. In reality they operate as a combined system anyway. Point being, it’s not necessarily more efficient either way and, it’s kinda viewing legs like reciprocating pistons with a dedicated power stroke which isn’t entirely accurate either.

Given in one of lionels latest videos he talks about his big chain ring being a 62 so the chain won’t cross.

Is your view now the same as it was then?

i don’t recall having a view then. i recall asking a question. 3 years later i remain just dumb enough to want to hear what it is blummenfelt is doing.

Where did he say that? I suspect this could be one of those things like “torque efficiency” was meant to mean “torque (comma) efficiency” ie they look at blood lactate, RER, co2 production as it informs cadence and power in order to determine “best” strategies to bike fast but spare calories for run.

Torque Effectiveness is a calculated ratio - see Sciguy’s link above or this page from Favero.

Hm, so the old bit about assuming it’s somehow better to actively “unweight” the off-power leg instead of letting it rest and be carried up.

So the Frank Day references weren’t far off.

Yes, it reminds me of the old spin scan etc from CT. I was more curious about context/interpretation of comments to see what he is actually looking at.
