S-Works 2010 Prototype

Racing triathlons professionally can be a tough life. You have to train your ace off day in and out then go to races to square off against the best in the world who more oft than not send you home crying.
But once in awhile something happens that completely redeems the difficulty.
Today was one of those days. UPS came by and it was a big box so I was wondering what could be inside. I was all pumped up and opened it right up.
Inside was this beauty. I'm pretty sure it's a 2010 S-Works Tarmac prototype. Looks to be debadged Zipps for the wheels which will top things off.
It's a touch heavier than previous S-Works. This must be due to some kind of engineering improvement they dreamed up.
Also, look closely at the shifters. Interesting touch there with the downtube shifters. I'm not sure what caused that change but surely there's a good reason for it. Perhaps they want to offer a product that can directly compete with bikes equipped with Shimano's forthcoming electronic shifting.
