I bought these for UCI cyclocross racing and they have been spectacular. Light and durable aren't typically things you expect from the same wheelset, but these really hit the mark for CX
This wheel set is my go-to for most cross courses. Has a great feel and gives me confidence through corners. It's definitely a stiffer platform than the WCX and rides more similar to a medium-depth road wheel set. The rim is super durable and has impressed me when I've taken some rim-strikes during races that would've cracked other rims. Overall I've been really happy running these wheels for all the fast courses here in New England.
My set of Cross tubulars is going on their 4th bike and they've required zero service in 5 years. Speaks volumes to the exacting build quality that these are still straight and true despite years of smashing roots I didn't see. Built up on DT hubs means that I can put them on any bike with some end caps which has paid off as they've seen QR, 15mm and now 12mm duty.
