Oh wow... so the Zipp NSW are shit?
Yes, utter crap.
So they release a more expensive and updated version of their 404... but perform poorer!?
Hopefully you won't receive a new letter from lawyers :P
So happy I did not buy them. SRAM and Zipp crap has broken too often for me but the bottomline.....the spoke hole and fin just looked too ugly. Plus $2k per wheel with no real evidence......although I did read of Field test indicating 454's were almost as fast as 303's

Only the wheels are changed between test runs otherwise the test is invalid.

I'm not quite sure what is the the Farsport V50 model?
All I can find is: https://www.wheelsfar.com/50mm-x-25mm-c ... m-25u.html

It seems to be referenced as FSC50CM-25U. Is the V version is a discontinued older model?

Quick question. Apologize if I missed this in the blog post, trying to get a clearer picture of the baseline. I know the test is done with rider on hoods, but at what bar width?

While the numbers would change on a 44 vs a 40 bar, I imagine the differences between wheels wouldn't change much, if at all, mostly just curious.

From a testing perspective, why the hell would the wheels care about the bar width?

They don't, but they give context to the numbers. Which is why things like, riding on hoods is mentioned, vs riding in drops.

You are trying to over complicate an already difficult test.

I'm not asking for them to test differing bar widths, I'm simply asking what bar width was used.

We need also test with small backpack.
I think it is more aero - i ride with mtb same track on mounatin. And descending on asphalt road feels harder without backpack. (Speeds 40-55kph).Little offtopic.

Might as well ask what colour jersey the rider was wearing :roll: :roll:

Don't forget to slap a Type R sticker on there. That's good for 5 watts, right?

42cm. You have to take the power output as a guide as it is totally at the mercy of factors that have bigger influence ie riding position. Dropping your head by a few cm can have much more of an effect than the difference between the wheels.

I spoke to the individual who owns them. They did come in V and blunt shape. The wheels tested were the sharp V. I don't know if the model number is still valid.
