I've got an 85 cannondale racing frame (with mavic hubs/freewheel (6 or 7speed)and mavic MA40 36 hole rims). I've been "out of the loop" for quite some time and am just getting back into cycling. Back when I was really into cycling (86-90ish) the "top of the line/lightest" was perhaps some Mavic GEL280's tubulars with 28 spokes, radially laced front, 2X rear, double butted spokes (15/16/15?) and alloy nipples. Boy has wheel technology changed! What was top of the line back then, is quite heavy to today's standards I'm guessing (comments?). I want to get a light set of wheels for my dale(something similar to 20 spoke ksyriums), only problem is I've got a few serious constraints(which I think only apply to the rear wheel as I think 100m front axle length has not changed). I want to keep my downtube friction shifters and have only 6 or 7 speeds in the rear (ie I don't want to buy an entire new drivetrain, especially brifters). I think my rear spacing is 126mm but I think I could spread the frame while putting a wheel on to accomodate 130 (comments on this?). My guess is that freewheels are out of the ?. It also seems like everything nowadays is a minimum 9 speeds in the rear (maybe 8?). I will be putting on a Mavic 851(861?-the one Lemond one the 85 tour de france with I think) rear derailler (which I don't think will do 8 or 9 speed very well)that has the suntour sealed bearing pulleys for what its worth(the ones the suberbe pro derailler came with in 1985, these are new though). Ideally I would buy a wheelset (front and rear), but maybe I'm better off buying separates since I'm thinking any of the current front wheels would work but I may have to do something custom for the rear. Basically I just want a modern light set of sweet wheels but all I want to buy is wheels (and perhaps cassette since I think I will have to). Also it appears clinchers have gained ground on tubulars since 1988. I'm open to either but prefer tubulars. I also have a new set of aluminum sealed bearing pulleys I could use(not sure of brand) which appear narrower than the suntour pulleys (perhaps these would be better for 8/9 speeds, if that is my only option?). Thanks for any and all advice.
