I just finished building up my bike, and overall, everything came together smoothly.
The build is full Ultegra Di2 11-speed, with a Dura-Ace 11-28 cassette and 53/36 chainrings. I'm running a C-Bear bottom bracket, XTR rotor up front, and a Galfer rotor in the rear. The cockpit features a 100x380mm integrated handlebar paired with a MagCAD 3D-printed Garmin mount. Out back, I’ve got some budget-friendly Chinese oversized pulley wheels, and the wheelset is a Fastop Wave 45/50mm — wrapped in 25mm Continental GP5000 tires with latex tubes. Saddle is a very light (75 gr as far as I remember) Aliexpress saddle which I used hassle free already on my other bikes for years.
Power is tracked with Favero Assioma pedals. As it stands, the total weight is 6.65 kg. Swapping to my climbing wheels and a SRAM Red cassette should bring it right down to 6.5 kg flat.
The build process was straightforward — everything lined up nicely, with properly faced surfaces and a smoothly spinning bottom bracket. The only small issue was the lowest headset spacer slightly contacting the frame, but a bit of sanding sorted that out easily.
I just got back from a 30 km shakedown ride, and honestly, it feels nearly identical to my Tarmac SL7 — which is a compliment in itself. It’s responsive, solid, and confidence-inspiring, with no noticeable difference in ride quality.
I will put S-Works stickers on it.
