French headset usable on Wicked?

[afterbang]

Hey guys,

Came across a cheap Shimano XT headset and found out after I purchased it that it's French. Does anyone know what parts I can salvage out of this to use? It's basically just the bottom cup I need, but I want to replace everything that's usable. Here's the product manual:

The ISO headset has two measurements for measurement B, 26.4/27.0 and the French headset just has a single 26.4 measurement for B...

Not sure if that means that the top and bottom races have a different measurement on the ISO???

This is the only difference other than the actual threads on the top parts. Hoping I can use some of what I bought!

Thanks guys

Is this a trick question? Consult Harris cyclery/Sheldon Brown site. Methinks its all usable except for parts that are threaded. But......

haha, I don't know if it's a trick question or not. that's the problem

I checked out Sheldon's info before I posted on here and the measurements for French headsets don't match what is shown on the instruction sheet... so maybe it is a trick question????

I just wish I knew why there are two measurements given for the ISO model.
