I am considering buying a San Andreas XC frame to build into a fairly light XC and mild freeride bike. I am trying to find out what the differences are between the DHS and the XC bike. The only obvious one is the rear shock, and I was wondering whether this accounts for the weight difference too? Any information would be great appreciated as most websites don't seem to tell me all that much. Also if anyone has a 2nd Hand XC frame or Bike in silver i may be interested in it.

Thanks!
