I saw one on the trail the other day. Looked okay, but the rider said he has had to return it twice for warranty. Cracked a chainstay at the same point both times. Right behind the BB Shell. Carbon bits for MTB are nice, but a whole carbon frame makes me nervous for anything other than XC racing, and even then, no jumps or drops, or big rocks, or roots, or dirt.....
Sette frames are okay, but carbon fiber frames is something I wouldn't cheap out on.
Generic re-badge type frame (bike) with run of the mill carbon from either China or Taiwan.
NOT that that's a bad thing since most medium to high end frames are from and made in China or Taiwan.
I believe a number of mail order houses spec Sette.
I bought a Tomasso Aggriazato from a mail order house with a "me too" carbon fiber frame and it is fantastic. NOT a Tomasso like we know it from Italy at all, although very decent quality.
