I would not recommend the Aksiums - they seem to be marketed to people who can't afford Ksyriums. What worries me most is that the Aksiums only have 20 spokes, so if you break one, it could ruin your whole day. 32-spoke wheels can usually lose a spoke and keep going long enough to get to a bike shop. If you do decide to buy Aksiums, make sure you have a few extra spokes, because you might have to replace one on the road, and because they use proprietary spokes that may or may not be in stock at smaller bike shops.
