Bicycle Mechanics - Chris King MTB hubs on Road bike

Does anyone know if my Chris King rear hub would work on my Jamis Nova bike. Both are 9speed, but is the spacing different on the MTB? Can I just throw on a normal road cassette onthe hub and lace up a 700c wheel around it and ride away?

Road spacing-130mm MTB spacing-135mm
So I can just stretch my dropouts to make it fit. It is a steel frame, so from what you said, it should work.

Yeah, you can spread a steel frame. You might have to realign the dropouts slightly.
I've done exactly that on my touring/commuting bike - spread the chainstays for XTR (135 mm) hub. The chainline of the 135mm spread is apparently better with a tripple chainring up front. I use MTB cassette in the rear, but the cog spacing is identical to the road cassette, so I don't see any problem with using road cassette. As a matter of fact, some frames have 132.5 chain stay spacing so that either type of hub can be accomodated without re-adjustment of the chainstay spread and of the derraueler (spelling?) drop geometry. I did have to fix the rear geometry, because the spread was quite large on my old bike, otherwise I couldn't get dependable shifting throughout the whole range, but now the bike is perfect.

Actually, if it was my bike, I'd be looking for a different axle set to convert the King hub to 130mm rather than spread my frame to 135mm.

Can't you remove the 5mm spacer thingy and change the axle?

WorldIRC, you take all the fun out, wouldn't you much rather go after your bike with a 2x4, struggling on the floor like you are trying to open the mouth of a gator.

I'd rather not kill myself thank you :)
I know that Sheldon recommends re-spacing using 2x4. I once tried a car jack, since the change is just few milimeters and is symetrical. It was quite easy, much less struggle than the 2x4 method. If, however, the spread doesn't happen symetrically and one needs to fix the geometry, 2x4 maybe the best way to do it.
