At the World Cup in Madrid that is. Every photo I saw on the Velo News website (6-8 shots) showed pros on hard tail MTBs, not a dual suspension rig in sight. Is that typical for pro racers these days? Does it vary with the terrain/course? One women racer there even had a Seven Ti hard tail. Pretty cool.
Given all the hype I hear about dual boinger MTBs that surprised me. At the end of the day a light, good climbing hard tail MTB might be faster in many situations I suppose. Dual suspension is great, but that's a few pounds you have to drag up every incline. I have been told that dual boingers climb better in many situations by keeping that rear wheel planted better. So go figure.
All the harder core MTB dudes I know are dual suspension fans. Pcad is a total MTB idiot and rides a hard tail.
