This is a 58cm Specialized Tarmac Expert. It comes with 11s Ultegra Di2 electronic shifting. This bike has a few upgrades starting with a nicer S-Works 90mm stem and S-Works Aerofly II handlebars. If you don’t think you will notice the difference of carbon handlebars, you’ll want to give this a test ride. The vibration dampening is great. Additionally, the wider bar allows for you to comfortably rest your hands and even your elbows if you need to get into a slightly more aero position. Those who have rode on highway 6 in a headwind both ways know what I’m talking about. Secondly, I installed the Shimano bluetooth connector which allows this generation of Di2 to communicate with your Garmin so you can see specific data on gearing and battery life, as well as control your Garmin screen without taking your hands off the handlebars. If you have noticed that I posted this a while ago, here is what has changed: The bike just got a complete service of the headset, bottom bracket, and free hub body, as well as a thorough cleaning. Additionally, it has brand new bar tape, Grand Prix 5000 tires, and brake pads. Why pay $3000 for this bike? First, this bike has been taken care of extremely well as I have been a mechanic for several years in the Vail Valley’s highest rated bike shop. Secondly, any new road bike from Specialized at this price point (or even higher) will not come with carbon fiber wheels (this bike has Roval C38) or carbon handlebars. If you don’t live in the area, I will professionally pack the bike and have it shipped to you (the cost of shipping will be included). Charger and pedals included. Will ship within the USA only. Lastly, the paint on this bike is truly unique and is guaranteed to make you at least 10% faster.
