I recommend Red shifters because of the Zero Loss on the right shifter.

The Red FD is flexy and not as good as the Force/Rival FD, which are the same except for the finish. Rival/Force FD are the same weight.

Force cranks because you get the BB30 option and you also get some decent weight savings over Rival cranks. Red cranks are just too expensive.

The Force RD is good because it saves a bit of weight for just a bit more than a Rival RD. A Red RD save even more weight, but it costly. And don't get fooled by the ceramic bearings that Red has, they don't do that much.

KMC chain because a lot of people recommend it. I've heard it's a good chain for the price. You don't have to get the SL chain, but it adds a bit of bling and saves weight.

Red cassette because of the weight savings. You could go with a DA cassette.

I recommend the Planet X brakes because they cost about the same as Force brakes, but are much lighter. I've heard good things about them and if you're worried about stopping power, get some Kool Stops.
