I'm in the market for a new 'cross bike (in my pursuits to create a cycling arsenal). I've got everything sorted out as far as frame, gruppo, and cockpit are concerned. The only thing left i've got to figure out is a wheelset. I'm 5' 8", weigh a hair under 160lbs, and will be using this bike for basic 'cross riding and potentially racing (also, might use it as a rain/snow bike to keep my road racer safe).
I need help deciding whether to use a road rim (appx 19-20mm in width) or a dedicated cyclocross/trekking/29er rim (appx. 22-25mm in width) and understanding what implications this will have regarding performance, tire options, and reliability. Also, I'm open to any hub suggestions you might have. Currently, I've been thinking about using Shimano Ultegra hubs for best bang-for-the-buck, ease of adjustment and serviceability.
Any advice would be greatly appreciated.
