Gotta wonder what your pace speed is into that kinda wind. Was out for an afternoon 50mile ride this aft when the wind decided to pick up outta no where, bad thing was I had the Cosmic Carbone SLs on... BAD NEWS!!! I had my head down in 53X19 and couldn't crack 30kmh, mostly down at the 26-28kmh area for a good 20 km of fun . The best was turning around and spinning a 53X14 at 50kmh for the majority of time.
