I wonder how much these babies cost?

Barloworld brought two styles of aluminum wheels in addition to two styles of carbon wheels.

The team brought the older Cosmic Carbone wheels with both aluminum and carbon braking surfaces for the flat stages, plus the new Cosmic Carbone Ultimate wheels and R-SYS aluminum for the mountains. While the older Carbone wheels are straightforward and built conventionally, both the Ultimate and the R-SYS are brand new and packed with interesting technology.

The R-SYS is a replacement of Ksyrium ES. It relies on 4mm hollow tubular uni-directional carbon fiber spokes, which are very stiff. In addition the new wheel utilizes a technology called Tracomp, in which the spokes are fixed to both the hub and rim so that they can perform in both traction [Tra-] and compression [-comp.] This way, less spoke tension is needed and it results in a 30-percent stiffer wheel than its predecessor the Ksyrium ES. The riders will choose this low profile model for its predictable braking and good manners when descending in crosswinds.

The Carbone Ultimate is positioned as Mavic's best all-round race wheel.

"It's designed to be the lightest aero wheel that we have for hardcore racing," said Sean Sullivan, Mavic's U.S. marketing director. "This is a totally new approach to wheels for us, it has carbon spokes, carbon rim and carbon hub. We've been working for a little over two years on this project with our racers and the technology is dialed in."

The Ultimate's rim is 40mm high and it's molded from 12K carbon fiber. The most interesting aspect is that the wheel does not use a mechanical spoke attachment system. The spokes, also made from carbon fiber, are molded to the rim and the hub. The spokes on the front wheel actually continue from one side of the rim through the high flange hub to the opposite side of the rim. Mavic claims that the materials and construction method combine to form a wheel that is very stiff.

Soler won stage 9 using a front R-SYS and a rear Cosmic Carbone Ultimate. Hunter won stage 11 on a pair of Ultimates.
