Thought I would post images of a bike I've thought about for a long time that is now a reality.
There are lots of people that helped me make this build a reality and my appreciation and thanks go out to all of them.
Initially I thought my biggest challenge was going to be integrating the Shimano Di2 components with the Clavicula crank. It turns out, this was no problem at all. The shifting is amazingly accurate and I have zero issues with what I thought would be a real headache.
I also thought I would have major issues with the internal Di2 cables rubbing on the MASSIVE Clavicula carbon crank spindle in the bottom bracket area. It turns out I had a brain storm as I was routing the cables and found a way to route the internal cables so they never even enter the bottom bracket chamber.
Here is a link to how I routed the Di2 Wires to stay out of the BB area: download/file.php?id=35378&mode=view
The build went surprisingly easy. Because there are no cables to stretch, the derailleurs shift perfectly after the initial set up and things just work.

Now that the bike it finished and I have about 300 miles on it, I must say the bike far exceeds my expectations. I knew I would like the bike a lot, but I wasn't aware just how nice a bike could be and how nice a bike could carve a turn until I rode my new bike.
Do I have any gripes about anything on the bike, well maybe. I'm not all that impressed with the Most seat post. It is the most difficult seatpost to adjust that I've ever had. There is a bolt on top that you have to access through the underside of the saddle and finding a tool that can do the job is very hard. There is another bolt, 5mm hex, at the bottom of the seatpost clamp that is easy to get to. But you have to work both bolts at the same time in order to get the seat just right.
Speaking of the seat / saddle. It's a Tune Concorde. I'm surprised how much I like this saddle. It's much more comfortable than I thought it would be. Have I had more comfortable saddles? Yes, but at a much heavier weight and this Concorde combines great design, comfort and weight all in one element.

I wanted a very light bike, but saving weight wasn't my main priority. It was important for me to have a PowerTap Powermeter and Clincher wheels. These two items are not the way to go if saving weight is your main priority. However, I think I did well as the complete wheel set including the PowerTap in clincher format was 1436g. I don't know of another powertap wheel set lighter that that.

I knew the new Dogma was about 100g lighter than the newest Prince, but honestly it's hard to find much info on the weight of Pinarello bikes. It was my assumption that Pinarellos were light but I really didn't know if they were among the lightest in the industry or where they stood. So as I was putting all the parts together in my head and seeing all these 11, 12, and 13 pound bikes, I thought my new Pinarello would be in the high 13 pound range or maybe low 14 range.
As it turns out, with the bike as it stands in the photos, with peddles and bottle cages etc. the bike weigh 14.89 lbs (edit add 100g with the Fizik Antares). Yes it's light, but it's not the feather I thought it would be. I know the Di2 stuff is a little heaver than other top-line stuff. The handlebars are also heavier than other bars, but even so, I thought my bike would be a pound lighter than it is.
Even so, I couldn't be more happy with this new machine. The way it feels is amazing, and it is a total pleasure to ride. For me a real dream bike.
Because the shifting is all Di2 I chose NOT to go outside of the Shimano realm and try other chains and/or cassettes. I wanted flawless shifting and that is why the chain and cassette is Dura Ace and not some lighter option.

Anyway, I had a great time making this bike a reality and wanted to share with others that might also enjoy it.

I love the way that big pulley looks. It's supposed to reduce drag and enhance performance.

Great design, super light (54g) and much more comfortable than I thought it would be

Some of the lightest skewers around, Great design too.

14.89 pounds (6.75kg) is pretty impressive considering that that includes a powertap, Di2 and clinchers. Add to the mix that you are running stock brakes (a good move IMO) and a cassette that will outlast a chain and all I can say is :shock: :shock: :shock: nice bike.

FWIW, if you went to tubs (-~130g in tyre/tube, ~90g in rim), with a light rear hub (-200g), red/SR (-~150g) silly brakes (-90g) and so on, you could drop about 1.5 pounds. But then it wouldn't have a power tap and electric shifting.

Bloody nice bike in my opinion.

Beautiful bike. I am sure it's a no compromise ride so even though it's s little heavier than expected.

Gorgeous bike!!!
What does the saddle weigh?

Should be a great performer AND one of the nicest builds I've seen. It really looks hot :up:

The bike looks dialed in, now it is time to work on the flexibility of the rider :)

Hmmmm. I am interested in your pulley and rear cage set-up. Was it a retrofit from a 7900 design or is it a new, clean-sheet design for the Di2? How does it shift in comparison to the stock set-up? Are the carbon cages more flexible than the stock versions?

Saddle weight is 54g, if memory serves me correctly.

My Di2 components including the special der. pulley came in the mail long before the frame. So, I installed the modified Di2 rear der. from the very beginning with with the special pulley. I can't comment on how the shifting is different.
There is a slight weight reduction with this pulley as the weight of the revised Di2 rear der. is 214g. According to the fabricator it "reduces the waste of power at the chain transition". Again, according to the fabricator, it has been tested in the TDF by guys like Danilo Hondo and Gilberto Simoni and they say it shifts better than the original.
I think, but not positive, that this pulley set up is different from their traditional Dura Ace 7900 non Di2 set up.

fa63, you are So Correct !!
I've been dealing with neck problems on the bike for several years. I've been told my arms are a good deal shorter than what my legs and torso would dictate. I work hard on improving my flexibility. I'd love to remove some of the stem spacers and flip the stem to a 'flat' position, but at the moment that would mean much shorter bike rides and big increases in neck pain.
You are a keen observer as you can tell my flexibility is in need of improving.
Believe me, I'm working on it.

Very very nice.
Any chance you will fix the stem and get some WW brakes?
