Different build kits on the 951. Top; 2010 Boxxer WC, Deemax etc. Bottom; 40RC2, Crank Bro's Iodine (?) wheelset. Both running Saint brakes, Cranks, etc.
I believe they are the Opium DH wheels. Either way they're shit, I'd take the Deemax's over them any day. The model on the top looks so much more fit it's not even funny.
