LeMond Poprad disc-brake convert how-to?zeroice

I am interested in purchasing a 2002 LeMond Poprad, based on the Reynolds 853 Steel alloy frame. The bike is moderately priced w/ many goodies. Its a great bike, but would be even better if you can install disc brakes on the front. If anyone knows if that is possible and can help me out on what parts to get, please let me know.

..even if some still pooh-pooh the idea.

You'd need:

1. Fork with a disk tab

The Dimension disc fork is an inexpensive option. Watch Bikeman's ebay auctions, I picked one up for $26.

Or you could try to source one of the forks from the few cross bikes that come disk ready, like the Giant.

And of course you can blow $200+ and get a nice custom fork done from one of more than a dozen builders, Hunter for example.

2. Disk front wheel

You have your choice of many mtb disk hubs. Cheap, reliable, and heavy would be Shimano Deore or XT for $20-30. Expensive and light would be Chris King or Phil Wood for $120. Midpriced and light, although not as nice as CK or PW, is the Hugi 240, which Pricepoint has a rebadged Hayes version for $80, or a better deal (if you had use for the rear) would be the full disc set for $150

The choice of 700c rims that can withstand the forces that a disc brake exerts is limited. You can look through the 29" Mountain Bike forum for ideas, such as the Mavic T520 which looks like it may hold up to the abuse, or Alex makes a 700C version of their disc only TD-17 rim for dirt cheap. Nothing light yet though.

3. Disc brake

This choice is actually pretty simple if you want to keep the STI levers - the Avid road disk brake is the only one I'm aware of compatible with the amount of cable pull from road levers. Easy to install, good feel, great company, but heavy.

If you wanted to switch to bar-end shifters, then you could use the Dia-Compe 287-V levers with any cable actuated disc brakes, such as Hayes or Formula, but Avid's mountain disc brake may be your best bet in this case as well.

I've heard that there's a way to get Hope hydraulic brakes to work, but I don't know anything about that.

I think that covers it!

Thnks for the info slacker joe.... that sheds light on much darkness. I'm not too worried about hi-end stuff, i'm just using the bike for messenging downtown Pittsburgh. Trying to stay in good shape during the off season. By trade I race motorcycles, CCS, middleweight (600) class. so riding the bicycle just keeps me in tune w/ two wheels :)
