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...

Re: Scientists say high cadence is inefficient

No. The body stores fat as energy source. Even "skinny" people have enough energy stored as fat so that they can survive for days without eating. The body stores relatively little carbohydrate, as glycogen (a polysaccharide) in muscle and liver. The article you linked compares 2 different...

Re: Scientists say high cadence is inefficient

………. and high force high Cadence pedalling forces the muscles to feed mostly from fat, so a rider with a low body fat percentage can’t afford to do high force High cadence pedalling for very long, and that’s why the skinny pros do it the way they do it. No. The body stores fat as energy source. Eve...

Re: Scientists say high cadence is inefficient

Actually, long as you’re making sufficent power, higher cadences are more efficient. The problem comes when your power at 80-90 rpms isn’t high enough to cause the fast twitch muscles to be engaged forcefully enough. https://www.active.com/cycling/articles/why-fast-pedaling-makes-cyclists-more-effic...

Re: Cleaning a bike

If you keep the jet away from anything with bearings in it, there shouldn’t be a problem using a jet washer. At this time of year I use a power washer because the bikes get properly caked in all sorts. Jet washers are brilliant at getting the caked on crud off, with minimum effort. Be especially car...

Re: Went for a ride

That’s often my stomping ground, when I’m doing longer rides. There are some dreadful road surface round that area of the world, but also some stunning scenery.
