I'm planning on making the first real upgrade to my Prophet soon and I think the first component that is going to go is the crappy rear hub. But, I'm not sure what route to take. If I purchase a new DT Swiss hub is it a big deal to have my shop switch out the old hub and lace the new one in with my old spokes and rim. I'm not sure if it would be cheaper to just purchase a rim, spokes and hub package or not. I like the 819's that came with the bike and wouldnt mind keeping them. What do you guys think? Thanks.
