I read a review on another site and it mentioned some of the specs for the xc6.

Aluminum "lightweight" frame
Shimano Altus shifters - 24 speeds for responsive performance shifting
SR suntour XCT V2 fork
Ninja 26x2.10 tires
Shimano crank
Tektro IO Disc brakes with shimano EF50 levers
KMC Chain
Acera rear derailleur



i will also take a look at the hardrock specialized. Will see if the LBS has it.
