why are those wheels uphill only? There are lighter wheels that have no descending restrictions. Carbonsports can you shed some light on this?
Braking surface less resistant.
"The “L’Alpe d’Huez” wheelset has been developed specifically for the demands of uphill time trials. To achieve the least possible rotary mass, the rim’s brake surfaces have been lightened. Thus, the brakes must be used sparingly and not with brute force. Only use these wheels in flat or uphill sections. They are not designed for the braking forces encountered when riding downhill. We offer other wheels for these purposes."
click on the wheel and then click on all the sections of l'Alpe...
