I am looking for a new pair of clinchers for my cross bike, but I also want to be able to use them on my road bike as well. I am looking at the Velocity A23 rim and either White Industries hubs in a 24/28 configuration at approximately $650 for the set or the same rims laced to Ultegra hubs in a 32/32 spoke set up at $300. The Ultegra set up will be about 500g heavier. I will use these for cross racing, maybe some gravel races, and for the occasional road ride. I am trying to justify the additional $350 for the White Industries set up, but I'm not quite there yet. Is 500g worth $350 more? I have already cleared either wheel set with my wife, so it's only me that needs convincing.
