Re: Lost cadence

The only metric I really care about is my heart rate. There’s an equivalence with power, and I don’t need cadence or torque sensors. I can count to 15 without too many problems, so every now and again I can see ( roughly ) what my cadence is, should I become interested, for any reason.

Re: Shimano press fit bottom brackets

The reason the manufacturers usually give for using PF type BBs is that it enables them to have more flexibility ( as in choice ) in their moulded frame designs. Why a steel frame would qualify is anyone’s guess.

Re: Overtaking roadies?

^ That is very strange. What was the nature of "the load of grief" ? i.e. What is there to complain about ? I think he must have been having a bad day. If he’d shot past and kept going, fair enough, but to struggle past, slow down, and then get the hump when I went on my way, was strange....

Re: Overtaking roadies?

I had my favourite type of thing happen to me at the weekend. I was riding a fairly undulating route, on my big old heavy hybrid. The inevitable ‘road warrior’ appeared, and broke his backside trying to get past, then instantly ‘blew up’ ( metaphorically speaking ) and was then just in the way, and ...

Re: Scientists say high cadence is inefficient

………. ‘Conventional wisdom’ seemed to dictate that high force high Cadence cycling was a predominately Glycogen fuelled, it’s been proven that it isn’t, and why . .......... Please show me exactly where it says high force isn't down to glycolysis. I have read and re-read https://www.active.com/cycli...

Re: Who makes your bike and is it important

At the lower end of the price range I don’t think it matters much. Same old same old with different stickers. The high end stuff is not that though. So it depends exactly which part of the range you’re at, as to how much it matters.

Re: Scientists say high cadence is inefficient

That seems like it says more or less what Colin said, only it specifies which type of muscle is using the glycogen. Yes and no. It also explains why anyone who thinks that high force, low cadence cycling will deplete fat reserves over Glycogen is wrong, and why exactly the opposite is true. ‘Conven...

Re: Scientists say high cadence is inefficient

The whole point of the initial article was that it's inefficient to ride at a high cadence in a low gear if you're not outputting enough watts. Yes, I know. When Chris Froome climbs a hill in a low gear with a high cadence, he's putting out enough power so that he's still at almost at peak efficien...

Re: Scientists say high cadence is inefficient

Hi, Clearly fantasy, average 300 what for power over 100 miles? Graph lack units to those figures? A lot of complete stops in speed? Yeah, total fantasy. You clearly know your stuff :lol: https://i.imgur.com/rqY4UtY.jpg Say hello to my little friend. For avoidance of doubt, those were his plots.

Re: Scientists say high cadence is inefficient

From what I remember, Stephen Roche used to timetrial at 105 rpm. Delgado was slower in cadence, something like 95. It’s all things relative though. This is a friend of mine’s TT effort the other day. https://i.imgur.com/zAJn1hH.jpg I’d describe him as a competent racer, and his idea of high cadenc...

Re: Scientists say high cadence is inefficient

Hi, I wonder though about high cadence as really it is used for climbing and on the flat Froome and others do have cadences in the 70’s pushing higher gears High force lower cadence pedalling forces the muscles to feed mostly on Glycogen / Carbs, and high force high Cadence pedalling forces the mus...

Re: Scientists say high cadence is inefficient

All but the first paper quoted are about outputting the maximum sustainable power over some time. That's where a high cadence works best. But the first paper quoted is about novices and recreational cyclists who sometimes stay in a low gear and spin quickly, even though the overall intensity of the...

Re: Scientists say high cadence is inefficient

Here's a quote from Marcus' article...… "....In one case the cyclists pedaled their bikes at 50 revolutions per minute (rpm) while using a high gear. In the second case, the athletes pedaled in a low gear at 100 rpm. The athletes were travelling at identical speeds in the two instances, so the...
