12 watts, really?

Beats the 2 watts that Cervelo is offering on their new S3 Disc.

Although, 2 watts + 12 watts + 10 watts for shaving my legs + 4.4 watts for an aero bar + 15 watts for a skin suit and before you know it I'll have an eBike that powers itself!

easily 24watts if you put snake oil in it...

Why would you sprinkle USN on your chain?

Nibali uses the same oiler, but he holds the car while the oil it.

He holds on to the car while they look for lube on the car floor[emoji106]

Orica (or who ever is testing this) is a bit late to the party.  

Nothing new .

This model could even lube  anywhere on the chain. Infinitely variable.  

 

PS and with calves like that, that  guy defiantly scoffed at a measly 12 watt

 

With those calves I actually think that is coolant instead of lubricant they are putting on.

If this moves me from 29875 place to 29870th place at argus I am in.

 

If this means it will give me 12 watt for nothing while cycling through the Karoo in December, hell sign me up for 2!

What's happening in the Karoo in December...? :whistling:  ^_^

 

 

That is probably the main event that I would say this would be a "life saver"

Hopefully there is somebody with better mathematic abilities to solve their "12W" saving, because according to me:

 

A perfect chain doesn't move relative to it's sprockets, so power cannot be quantified.

 

The only area where power could possibly be lost, is at the jockey's pin with the jockey wheel's relative rotation.

 

A clean/lubricated chain doesn't save you any power.. Their methodology is all wrong.

Hmmm, not quite sure of what you're suggesting. But let me try it this way. Consider a single speed, so chainwheel, chain and sprocket. Apply power, or energy in a fixed time, on the chainwheel and the chain will at least bend and straighten as it travels round the chainwheel and sprocket, yes? So there's energy required to do this? Lost energy (or power). You can hear the chain running? So mechanical power has been converted to sonic power, again a loss. Etc etc. The end result is less power arrives on the rear axle than was applied on the chainwheel.

 

Edit: take this a step further. Dry, unlubricated chain, sounds noisy? Lubricated chain, preferably not with Superglue, sounds....less noisy! Lube reduces lost power. Scale-up with more chain bending and straightening round jockey wheels, more lost power.

Well let's conduct an experiment to see if the movement of chain links has any bearing on power required to turn pedals; Go home, lube your chain with super glue and come give feedback on how that worked out for you.
