First, I have a hard time imagining why anyone would own a training clincher that weighed less than a deep carbon tubular like a 404. Second even if the traininng wheel did weigh less, how much less could it weigh? More than 100grams? I'd still take the aeroness of the 404 type wheell in a heartbeat. LP is still a loop course and what goes up must come down, so there is a whole lot of aero to be gained.
As for the disk... Most disks weigh less than 1250 grams. Some a lot less. How much might a training clincher weigh? IMHO they'd have to be feather weight for the savings to overcome the aero advantage of a disk.
Just one person's opinion, but I don't see the weights of most wheels being that different, but the aeroness can be all over the map. I'd take a disk for anything, but an uphill TT. I'll be running a 404/Renn for LP '04.
If I owned a rear 404, maybe, just maybe, I'd consider it instead of the disk, but I certainly wouldn't buy one just for that race.
