I'm interested in the a23's because of the 23mm rim for the apparent tubular like ride quality, but I don't want to sacrifice durability if I'm going to get a custom wheelset built. I'm trying to find the most durable, yet still reasonably lightweight training wheel for around 500-600$. I saw the Velocity a23's laced to White Industries on Wheelbuilder.com and was wondering about the durability for a 180lb sprinter but still able to handle a lot of climbing.
