^^ as above. I’m sure they’ll be fine for traditional cyclocross.
IME they’re kinda pants for anything more gnar though. Very strong wheels: but only up to a point. Once that threashold is exceeded, though, they suddenly go from utterly bullet proof to ‘funny’ and appear to be virtually unfixable. Then they’re pretty much good only scrap (hub, rim, spokes, the lot). Other wheels seem to give you a bit more warning before that. Its a complete PITA to build new rims on to ’em and/or find a suitable rim to replace the trashed one.
…a bit of a contrast to more usable traditional spoke / hub combos, which are generally easier to true up and / or replace bits as they go wrong.
Just my experience though (a 2nd time trashed rear Aksium user) 😉
