Note the new more rounded wider profile.
I rode them in some fairly windy conditions, (windspeed around
30kmh with gusts to 45kmh), and I honestly felt no difference
between them and my C24s. If anything I maybe felt a bit more
stable. I weigh under 65kg, so that was very unexpected.
Overall the Mavic Cosmic Pro Carbon SL feel like an upgrade. The
kind of upgrade where you 100% notice a valuable difference. The
stiffness delivers extra speed, putting your efforts directly
through the wheels and into the road. Like all upgrades and pricey
bits of kit, they work best when you put the effort in. I feel that
strong riders will get the most benefit from them: riding over
40kmh for extended periods, climbing out of the saddle and
descending hard, the Cosmics come into their own and pay back your
effort. That said, they don't hinder less hard efforts.
I'd definitely buy a set, it's as simple as that. They represent
good value in comparison to other similar wheels and the braking is
very effective. I wouldn't ride them as winter training wheels, but
then I'm not sure who would; That's not what they're for.
If you are looking for solid, relatively light (1450g), carbon
wheels, I'd recommend checking them out.
The Mavic Cosmic Carbon Pro SL wheelset, including tubes and
tyres, is available now at £1,600.00.
