De Rosa SK Pininfarina w DuraAce Di2 Specifications: This Listing is for a Limited Production DE ROSA SK Pininfarina Road Bike with Shimano Dura Ace 11 Speed Di2 Components. I purchased the Frame from the UK in 2019 and proceeded to take my time to acquire all of the Components. Over a 3-year period I spent over $10,000 on the Bike & Upgrades. The Wheels were upgraded to Campagnolo Shamal Ultra C-17's ($1300+) to accommodate the popular wider 28c Vittoria Corsa Tires. They replaced Campy Zonda Wheel. The Direct Mount Caliper Brakes are a major improvement over Single Mount Rim Brakes. The Di2 Components were upgraded with the New Di2 Bluetooth BT-DN110 Battery and EW-WU111 Wireless Unit (>$300 w Installation), which integrate perfectly with my Garmin 1030+ to show Battery Charge, Chainring & Cassette Gears. The Red Selle SMP Dynamic Saddle is also new ($269 w Tax). I can switch to a Specialized Power Short Nose Saddle if Buyer does not care for Seller SMP saddle. The Shimano Di2 Charger & Look Keo Pedals will be included. New Red Deda Elementi Handlebar Tape will be included as I noticed some tape wear on the current Tape. The SK weighs approximately 16 1/2 LBS. The Bike has been meticulously maintained by me and my Excellent Mechanic. The Derailleurs show normal use wear marks and the chain was dropped once causing minor scuff marks at the Bottom Bracket. Ideal Rider Size 5' 6" to 5' 8".
