I have a Race, and it's pretty awesome. (You can't trust my opinion really though, as I haven't ridden any other carbon bikes!) I chose the Race over the Pro and SL mainly because of its looks — I didn't like the glossy white of the Pro (or its white bar tape) or the orange piping on the Pro. Plus the Pro was too pricey! (The Mavic wheels and the upgrade to Ultegra also helped — the Ultegra brakes are fantastic). All I've done is added Crud RoadRacer mudguards and changed the tyres — there was something about the Mavic Aksions which didn't fill me with confidence, so I put Vittoria Rubino Pros on instead. (I would have put Gatorskins on, but they wouldn't fit under the mudguards). I'm not totally sold on the saddle, but I need to do a few more long rides on it before I can decide if it needs to go or not.
