Subject: Am I aero crazy? Should I spend the cash on a Zipp Disc????Hi all...I am doing my first Ironman (IM Florida ) in November. I have a history with cycling - used to ride USCF races in high school and college and am averaging about 18mph for a 5 hour ride at the moment. I have a set of older 2003 non-dimpled Zipp 404's that I've used in 1/2 IM's and Olympic distance races. I have been seriously considering either a Zipp 900 or, ideally, due to it being faster and allegedly more comfortable over the long haul, a Zipp Sub 9 disc. I ride a Felt DA with Campy Record and Oval Concepts A901 bars. I know a disc vs. a 404 rear should make me faster, and I've seen the data on Zipp's site, but still can't decide whether or not to spend the money. I plan on riding some time trial next year, and doing at least 2 Olympic and 1 1/2 IM next year, so I would get some use out of it beyond the IM FLA. I CAN spend the money, but money is tight and there are a lot of other things I could spend $1200-$1550 on (cbike has a 25% off sale until sunday night ). Should I just stick with my 404's considering I am a middle of pack age grouper or do you think it's worth the plunge? |
