I ordered a carbon fork with a 15mm TA - disc brake. As was mentioned here in an earlier post there are a lot of wheelsets that have a 15mm TA front wheel. I plan to run between a 38-42mm tire on this bike, so I was planning between a 19mm-22mm internal width wheel. Since this is an "allroad"/touring frame I want some solid wheels so I was thinking minimum 32 spokes.

Are the 29ER wheels made with heavier gauge rims, bearings, or heavier spokes than 700c wheels? Or are they basically the same with just wider widths available in 29ER?

It seems like I might get more wheelset for my money with 29ER. Which would you go with if you were doing this build?
