Not here. Most of the xc guys also dh etc.
There are some hardcore old school xc guys that might make fun of you for needing a long travel bike on such a such trail. But speaking from experience, anything *can* be ridden on a xc steed. Just depends on the skill level of the rider. These guys would smoke you and then offer you a smoke talking about the good ole days on modified beach cruisers etc...they don't hate, they just want the young to remember

To them everything is xc...some is faster, slower, bigger, badder...but still just good ole trail riding.
