ok, i'm not totally thick, and i can see much of what you said is word vomit.

P = W/T = F*V

so when measured at the crank, what velocity is being used to calculate power?

I ask because it will take much less force to move a bike at X miles an hour in the big cog than in the small cog. you just have to pedal faster.... in which case you use cadence as the velocity... which is rotational among other confusions... which seems very strange...

i'm not trying to be inflammatory, just wondering if the two points of measurement are truly interchangeable.

although now that i'm thinking about it, they have to be interchangeable. otherwise there's a hidden source/lose of power.

so final question... they must use cadence as the velocity?

Yes, cadence is the velocity, and not really confusing. Think of how they measure horsepower in cars

(lb/ft*RPM)/5252

Legs are pistons, pedals are conrods and a crankset like a crankshaft.

No.

No No No No No.

What rear hub is that?

Please pay attentions....

No.

No No No No No.

Listen to their reason!

more like it!

What rear hub is that?

Chub hub

Larger flange = shallower spoke pull angle. Chub say that you end up with a stronger wheel where the spokes don't need to be under such a high tension.

chub can say whatever they want that is one fat ugly hub

good start to 1002, can we just forget 1001 ever happened?

(edit) These were once cheap and common at one point, still nice though (edit)

Have a gold star. Power is, as you say, force times velocity, but it is also torque times angular velocity.

One could, in principle, measure the power driving a bicycle by measuring the forward speed and the horizontal reaction where the wheel is bolted to the dropout. In fact, that's essentially how railway locomotive power is measured using a http://en.wikipedia.org/wiki/Dynamometer_car

i'm struggling to learn in this malignant environment. I demand respect, dammit.

great post :)

Not a great photo but my mate's Canonndale looks perfect; sublte with little bits of flash

Nice!

Oh dear.

About the most uninventive boring build I have ever seen

FAR from porn

i like how the used the steel fork as the rear seatstay =))
