scott claims 25% lower drag than previous addict. should equal the cervelo/madone on aero drag. the weight is impressive. ww need to remember
rca is built around proprietary BBright. when you run heavy rotor adapter the rca is over 700gm. the addict fork is lighter than the rca.
shimano press fit bb86 weighs 65gm vs 137 for rotor 24 adapter.....memo to cervelo dump the bbright and go with shimano bb86 or bb386. http://www.rotorbike.com/products/road/ ... t-frame_43

Or you could just get THM BBright bottom bracket at 91 grams. The Cervelo's weight includes hardware such as front and rear derailleur hangers, all bottle cage bolts, the grommets for the cable routing, and the seatpost clamp.
In other words, the frame alone is in the 620 grams range. Even with the weight added by the THM BB, it's still about 100 grams lighter than the Addict. I'm not sure how much lighter the Addict fork is than the Cervelo fork. The whole steerer tube of the RCA is covered with the Nanovate coating so it is likely that it will lose more weight in cutting the steerer than the Scott. Maybe 20 grams heavier in the end, depends on how much steerer these forks are measured with. The RCA also includes an integrated magnet. I don't think the Addict has that.
Yes the RCA is considered a "limited" production frame. But if it is valid for the Protour, it is certainly the valid benchmark.
