go tell ENVE their wheel R&D is crap, and that unstable aerodynamics and steering torque can be casually dismissed, as in your use of physics earlier.

So as well as a couple of "physicist mates", you are now in the inner circle of a major cf wheel maker?

I don't understand how he can keep going without providing any sort of an argument. Amazing to watch.

Eh?

As far as I can see Alex is supported by ENVE. They push there wheels, especially the deeper ones, as being suitable for climbing.

BWAHAHAHA If your event lasts less than 6 seconds, get the lighter wheel.

I think the real question is how much does 500 grams affect you on a 5 and 10 percent gradient, because gravity is the key. What is the 0/30 acceleration for 1000W on these gradients? What is the difference in speed and distance?

So at the risk of posting something on-topic in this thread, does this mean throwing on a set of deep dish wheels is roughly the equivalent of dropping 4 kilos, or am I interpreting this incorrectly?

I have seen the tables a couple of times and they need to be shot over them, so hard to read (and I'm a visual learner!)

The take home is that aero wheels can bring really silly improvements in your performance, if speed is important to you.

Aero, or light, it doesn't really matter. In the end the critical thing is that your wheels make that 'wo wo wo wo' noise. If they do that, you will fly.

Totally.

The noise means fast.

So to are cassette bodies that make a real loud noise when free wheeling. Just do that in the bunch and everyone knows you are a force to be reckoned with.

I love this thread, second only in entertainment value to the Reid cycles thread.

But I digress. After all is said and done, which wheels do I buy?
I ride several bicycles, but not at once.

OK what does the 2.4% cumulative efficiency one gets from the (wo wo wo wo :D ) wheels translate to in terms of speed on the road based on pumping out the same wattage? Say based on a 30 km/h on standard wheels, would that mean I jump to 30.72 km/h or is it not that simple?

erg...my heavy and non aero 32 spoke box section rim wheels make that noise. So...confused!

Back in the '70's I had a Raleigh Grand Prix with chromed steel rims. Man, they were FAST wheels - especially when I jammed the brakes on while riding in heavy rain. The wheels didn't go "wo wo wo wo", I did.
