I am looking for a hardtail frame that can handle XC (possibly racing), and light fr/aggressive trail duties. The Santa Cruz Chameleon seems to be a great fit for what I want, but I was wondering if there are any comparable frames I should be looking at as well? Capable of running at least 5" or more, and also going down to 4" or even 3". Also, it has to be relatively inexpensive. The Chameleon retails for about $450-ish. Thanks.
