The I-Speed line is something special for every road bike fan, but not only for them. The new season brings changes in the entire road bike collection: new designs, new shapes of the frames, better materials.

At HEAD Bikes we don’t believe in compromise. As a result, we have opted for a single, top-end frame and paired it with various groupset and wheel options to suite your specific requirements.

We have 3 standard specifications, Shimano 105, Shimano Ultegra Mechanical and Shimano Ultegra Di2. However each option is extensively customizable.
