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

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 muscles...

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.

Re: Pressure Washer?

I've just fixed up a neighbours second hand purchase (a Carrera Vulcan MTB). The bike looked pristine, it was very clean and scratch free but on closer examination had binding hydraulic disks, loose headset and wobbly BB. This turned out to be rusted disk pads, knackered headset bottom bearing+race...

Re: Shiny bikes & their advocates

Michael Hutchinson makes a similar point in his book "The Hour", he put it down to the differences in VO2 max etc that we are born with. GCN did a similar video and found that the 1k bike was 'slower', but not so much it was worth paying the extra. Which has pretty much been my experience...

Re: Shiny bikes & their advocates

If the engine is no good, you can spend as much as you like on a fancy bike, you’ll still get passed by a bloke with board shorts and flip flops, on a 5.99 BSO.

Re: Tyre trouble

The rim is probably worn down at the braking surface, as they get thinner, they get weaker.

There really aren’t. Those two come with a lifetime warranty on frame and forks as well.
