Subject:RE: Another training wheel question... sorry
The Aksium is a complete wheel from the factory and the Open Pro is a rim, so you (or the wheelbuilder) pick the rest of the set up. The Aksium has a low spoke count while I think the minimum on the open pro is 32.

As Daremo said in your other post, with all things being equal more spokes make for a stronger wheel. A poorly built wheel with 36 spokes will go out of true faster than a well built wheel with 20 spokes.
