Vintage MTB build help
I have an old Specialized Rockhopper Comp I want to upgrade. The bike needs new wheels. Seeing as it has 130mm spacing, can I build some new wheels with Ultegra hubs to make it a 9 speed? I really don't want to respace the frame. Lots of cyclocross racers use Ultegra hubs, so they must be durable. Anyone ever try this?

on the other hand, there's not really that much difference between 8 & 9 speed, is there?

To the op, the biggest difference will be the flange spacing. So the wheel will have less lateral strength than one built with 135 spacing, or a 130 built with a 7spd hub.

there is, granted, a gear differential - but it doesn't sound like the OP is off to the races right now...

i had a nine speed on my old saracen which was built for eight.
it was a bit of grief getting the wheel out sometimes, you'd have to give it a bit of a thump, but other than that it was ok.
no prob's
