OK So i had a curb find and I think I'm ready to dive in. I picked up an old Mongoose MTB w/o any wheels with vertical dropouts. OK it was stuck in the snowbank on the curb. I had thought about converting an older road bike but just could see it.

OK so if I'm going to do this I'm going to do a Flip flop. I need to find some wheels as well as a hub. Since I'm just getting started would I be better with 32 or 36 hole rims to make the hub search easier?

Thanks
