/ Performance

Buying carbon wheels is an investment that should yield greater speed (apart from better looks ;) ), and that is really about both lighter weight and aerodynamics.

Simply put, for the same amount of power, the lighter and more 'aero' you are, the faster you will go.

Hence, when speaking carbon wheel performance, we'll use wattage (power), speed (km/h) and CdA (aerodynamic coefficient), as key metrics.

Below are the results of a power & speed test, CdA test coming soon.

Check out some of the photos from testing day!

We will also be launching testing services as a way to provide everyone the ability to find out how aero they are and if carbon would boost their performance, AND organising test-days throughout the year so you could come and try Negative Split carbon wheels!

Our choice of traditional alloy wheels were Fulcrum Racing 5 Front and Shimano RS

Ultegra back.

The ride felt solid, although it took slightly longer (than we're used to) to pick up speed and reach the 220W average wattage target.

33.2 km/h

The first set to rival traditional alloy was our 38mm deep full carbon (23mm wide), rim brake. Coupled with Novatec hubs.

 

The lighter weight was noticeable both at handling and acceleration right away, and pedaling faster (higher cadence) was fairly easier. It also felt a slightly more rigid ride when compared to alloy.

34.7 km/h

Time savings

20K - 1'34"

40K - 3'07"

90K - 7'02"

180 - 14'03"

We then increased carbon depth to 60mm, the specifications versus the 38mm were the same.

 

Again, weight was the first thing to notice; the set felt a bit heavier than the 38mm although very responsive, and acceleration -even though it was perhaps slower than with the 38mm, felt quite similar. Sustaining an average output of 220W was easier than with the previous set.

35.o km/h

20K - 1'52"

40K - 3'43"

90K - 8'22"
