I use my Komodo for trail riding...it's suite well for it.

I think the Chase depends on your height. It's more of a Jump Bike...as is the Mongoose that I posted a link to. You really need to have a long enough top tube so you're not cramped on the climbs...and a long enough seat tube so you get decent leg extension for pedaling.

I'd look more into a Jamis Komodo, (Or Trail X if you're not gonna jump much)...or the Specialized Hardrock line.
