FTP W/kg - which weight are we talking about?

[Vetplant]

I get what you mean

BUT how on earth have you lasted 5+ years on the hubsa?

Good point, I usually keep my mouth shut and just move along to a topic that is moving along. Yesterday was just one of those days where I needed to vent.

Normal service will continue, expect another outburst in 5 years time  .

 

Don't mind me, continue the discussion ad nauseam...

^{Hmmm, you missed the answer to that one in the all the turgid stuff didn't ya!}

I don't like power training, cycling is about having fun, power training isn't fun.

Did you at least learn something from this?

For each FTP there is an equal but not exactly equal other FTP

That you should rather just ask google.

Yes.

 

1. No one actually knows what it means.

2. It's what you do with the number that counts

3. This thread exploded very quickly! Just wanted to know what the weight was they were talking about.

....but you (eventually) got the mass you were after? And if in doubt about that, refer to your #2.....

[Patchelicious]

Yes.

I don't agree. Lots of people know exactly what it means. Just because a few have a different take on it, doesn't mean that nobody knows.

 

That's like saying ALL news is fake because of Huffington Post.

I did get my mass.

As far as i know and understand, it is your body weight. Most bikes etc wiegh prety much the same and are on the UCI weight limits so including bike weights has no relevance then.

 

From the point of view of 'how fast do you go up a hill' the bike weight does matter. If you have a 50kg rider and a 80kg rider, both on 7kg bikes and both putting out 3w/kg the 80kg rider will go up a hill faster.

 

Why?

Because 80kg x 3w/kg = 240w output that the rider is generating

and 240w / 87kg = 2.75w/kilo (of the kilos that that you're have to carry along with you - gravity doesn't care if it is you or the bike that is heavy)

 

50kg x 3w/kg = 150w

and 150w / 57kg = 2.63w/kg

 

It is only if the bike was weightless (wouldn't that be nice?) that the riders would perform equally. 

 

If the lighter rider had a 5.4kilo bike in the example above then their speed up the hill would be equal. There's also the issue of friction (which would mean the penalty on the lighter rider is less severe), but I've ignored that to keep it simple.

 Uhm... Yes... That's why all the world's best climbers are such fat bastards... NOT...
