Subject: RE: Zipp Wheels I'm doing IM Japan in a little over a week, which is considered a "hilly" course, with a 404 rear and a 303 front. I think this is a good combination if you're riding "hilly" or windy courses. As was mentioned, the weight saving alone is worth it. I actually was changing the rear cogs on my training wheel and 404 the other day and decided to weigh them. The rear wheel alone is over 400g lighter than my training wheel. Probably over 600g for the set. |
