Deep Section Or Not?


New Member
okay, which would you choose if you were to buy a wheel for time trials and road races?

mavic kyserium or mavic cosmic carbone?

the kyserium are a bit cheaper and ligghter, but obv. not as aero as the deep section cosmics.

any thoughts/

In would go for the lightest wheels I could afford. You have to look at it from the point of view of which quality will be more likely to make you go faster more of the time and that is lightness.

Depends on what you would do more of. if you was to do TT more I'd go for the deep section, if your racing more I'd go for the lighter of the wheels, but again depends on what sort of racing, if it's road go for the deep rims, if its crits I'd go for the lighter ones. What I'm trying to say is it depends on the type of course you'd be riding.

Lighter wheels are great advantage on hillier courses but the deep rims are great for flat out speed.
