I’ve got some of the Roval Traverse EL’s on my hardtail. Bought them cheap recently too. So far been very impressed, and they are still very very light.
Heard plenty of scare stories about how flexy they are, but I’m 12 stone and not particularly light or graceful in my riding style, and I can’t say I’ve noticed any flex.
Like you say though, most people will recommend Stans on Pro2’s. Nothing wrong with that at all, in fact they’d be easier to fix if anything ever broke as they’re all off the shelf components. Personally I can’t stand the noise of Hope Freehubs though, it drives me potty! The DT Swiss in the Roval’s is much much nicer…
