Inexpensive deep-section aero rims?
Hi,
Can anyone make some recommendations for some inexpensive deep-section aero rims? Something similar to the Zipp 404 and the like. Inexpensive probably precludes carbon, but I'm interested in aero, not weight. 40-50mm deep minimum. Any suggestions? Joseph |

If any of the writings of Steve Hed and John Cobb are to be taken at
face value, you'll need a minimum of 60mm, preferably around 80+ to gain any truly aero benefit. At that rim height, anything but carbon is weight-prohibitive. |

They ship directly from factory for EUR 250 each + shipping. I'm told that you can use regular nipples in them as well, though I have not verified this. Nor can I find weight for a rim only (complete wheelset is 1470 g) /Robert |

Do you have a link to those writings? I'm trying to get some info on aero wheels... specifically, I'm interested in aluminum rims, and I'm wondering if there is much benefit to going from 20mm to a 30mm rim depth. I found some test data at Zipp: http://www.zipp.com/tech/aero.shtml I'd expect them to be a little biased, but they actually show Ksyriums being almost as good as their 202s at shallow wind angles. Anyway, they definately show a benefit with the deeper rims (especially at large wind angles), but the 202s and Ksyriums are still way better than the GL330s. -Ron |
