Tires are a big deal for efficiency, like Eric said...my "fast" tires are Conti Race King Protections.

As far as lockouts, the only lockout I ever use is for the fork. Even then, it's only for road climbs and sprint finishes. When building my bike, I opted for Fox factory fork and shock with the adjustable compression, but not the remote lockouts. These flex-stay XC bikes peddle so well, that a lockout isn't even needed for the shock IMO.
