Subject: RE: looking for a disc I only use the cover for race day, the easy "pre-race" ride the day before...and one ride 3 days out to insure everything is working as expected. I do 95% of my training rides on my Zipps as well...while I do still have the R500 wheels that came with my P3, I just prefer the feel (and look...I won't lie!) of the tubular Zipps to my clincher "training" wheels. I'd feel kind of silly using the disc daily. As for race conditions....from what I know and understand, there are not really any conditions to not use a disc...except perhaps gale force winds! Much of your weight is over that rear wheel, and it does not turn, thus, it does more cutting through the wind that letting the wind push you around. NOT so with the front. My 404's seem to have a profile that works well in higher winds where you'd not want to have anything deeper, like an 808 or 1080 profile. They are also fairly light wheels, so hills are not an issue either. Overall, these are great wheels. I purchased them locally via Craigslist. They are from 2009, dimpled, but pre-Firecrest. Got them for well under $800 including skewers, pre-glued tires (which I've since worn out and replaced) and an Ultegra 11-25 cassette (Which I've swapped for an 11-23.) Oh, "tri-geeks" ROCK!! |
