Isaac Proton Di2 Road Bike.
I am Isaac Proton Di2. I am a purebred racer. I have everything you would expect a high-end racing bike to have. My ruggedness and reliability are based on the best possible combination of weight and stiffness. I challenge every experienced cyclist to get the most out of me. My technologically advanced carbon-based design allows you to take up the most extreme challenges with me. Regardless of whether we’re doing a daily training routine or taking part in a racing competition, we face the elements together as one.

My frame is made of three different tube profiles. The profiled oversized slanting and horizontal tubes leave the frame head with the same tube diameter. The strength of the frame is guaranteed by the slanting down tube, which retains its oversized oval diameter over its entire length. The profile of the top tube, between and the head tube and the seat tube, goes from a rounded rectangular shape to a flatter oval shape. A standard round seat tube completes and stabilises my triangle.
Changing gears becomes easier, effortless and faster with Di2 by simply touching the shift buttons. Control at your fingertips. Additional benefits include an automatic trimming front derailleur, great accuracy plus easy adjustment and installation. Di2 continues its great success with Shimano Ultegra. And it makes no difference if these roads are cobbles, tarmac or mud.

I'm able to neutralise any road vibration with the help of my tight rear design with relatively thin seat stays and slightly higher chain stays, ensuring that none of the driving force is lost. The use of tube profiles with unique carbon-based properties allows us to work together to lead the pack on any kind of terrain and to beat out the competition! With my slightly curved front fork, bends are not a problem but simply a challenge. I am Isaac Proton. I will steer you to your greatest successes!
