Bianchi Oltre XR4 CV Chorus 2017 bike designed in Italy using the most advanced technology is unquestionably an Aero Race machine and the bike of choice for the LottoNL-Jumbo Team. Taking design elements from their Aquila CV Time Trial bike such as the tapered aero, 1.1/8” to 1.1/4” head tube and bladed fork design, and extending the aero elements of the down tube, seat tube and seat stays, the XR4 is visually more aggressive than the XR2 and the addition of a Vision Metron 5D integrated handlebar and aero wedge seatpost enhance this aesthetic on the complete bikes. Pleasing as this may be to the eye, the obvious benefit to the rider comes from the frame’s reduced drag. Bianchi, while not releasing test results, claim that the frame offers a 20 watt improvement over the XR2 – largely a result of the aerodynamic improvements. This is no small gain and will be welcome news for those racing the XR4.
