OK, I'll buy that. The reason I asked is b/c at first glance it seemed like that the mount bolt might be too long without that nut for a threaded dropout.

Another thing to note about the VX rd: on mine the jockeys (including the dust caps) are specific to their position (guide or pulley). If you mix 'em up they may not turn smoothly.

Not to highjack, but one more q: I'm in need of a barrel adjuster for my VX. But it seems that it uses a smaller diameter than a "normal" size brake adjuster. Does anyone know if this size adjuster is commonly available?
