A customer brought in a Ksyrium Pro Carbon wheel for service.


It's a tubular version.
Looks like the outermost layer of the Smart Envie rim has been given a cosmetic carbon finish.
It's a wheel built with a moderate rim height using Isopulse (radial lacing on the freewheel side).
Whereas the conventional steel-spoke Ksyrium Elite came with 18H front and 20H rear, this wheel uses 24H in the rear.
Mavic rarely does this, but they've adopted square aero spokes with spoke weight comparable to CX-RAY, which is probably because of the 24H rear configuration.
Mavic tends to use rather robust steel-spoke wheels without worrying too much about increasing the catalog weight.

The spoke heads on the freewheel side are held very securely.


Since it's from the same customer, I'll bundle them together.
This one is a Cosmic Pro Carbon in clincher format.
Since it uses the hub from the Ksyrium Pro Carbon, unlike the conventional Cosmic, it has 24H in the rear and Isopulse lacing.
Swapping just the rim height to switch between Ksyrium and Cosmic might seem like a shortcut... but not quite.

This one uses wide elliptical aero spokes with a sharp profile that could cut your fingers.
Compared to the Ksyrium from earlier, the spoke weight is different and the spokes are shorter, so aside from the aero characteristics, the wheel stiffness is different too.
During inspection, both wheels had some lateral centering issues on the rear, and the Cosmic was particularly bad.
