Right folks...have narrowed the search down to the following contenders...
Mavic Cosmic Carbone SLR - 1595g - Clincher
Zipp 404 - 1615g - Clincher
Corima Aero Plus - 1560g - Clincher
FFWD F5R - 1475g - Tubular
Zipp 404 - 1250g - Tubular
Obviously there is a weight penalty with the clinchers, but also the convienence factor. Clearly the 404 tubular is the lightest, but also the most expensive. Worth noting the Mavic SLR clincher is lighter than the 404 clincher. Anyone any experience of the SLR clincher ?
The FFWD F5R is reasonable weight and the cheapest there. Could almost afford 2 pairs of these for the cost of the 404 tubulars. 225g saving on the 404 tubular over the F5R for £900, is that really worth it ?
Thoughts guys welcomed....
