Billed as an endurance race bike, the Bianchi Infinito CV Disc blurs the line between a full-on racing bike and endurance bike. While the geometry leans towards endurance riding, a large portion of the bike's comfort lies in its frame technology.
Pioneering Kevlar-infused C2C frames in the early 2000s, Bianchi has continued to develop vibration-reducing comfort features with the Infinito CV through their Countervail vibration cancelling technology. Developed in collaboration with the USA's Material Sciences Corporation, the unique technology is integral to the carbon lay-up used and results in some flex to allow compliance and comfort over cobbles, harsh roads and on longer rides. Bianchi claims that their proprietary use of this material "dramatically reduces road vibration .
While the Countervail technology takes care of muscle fatigue, the frame's geometry also adds comfort for the rider on the bike. As frame dimensions follow size progression, it is difficult to compare the Infinito CV's geometry next to the racier Specialissima or Oltre models. For example, on a size 47cm the headtube is 140mm whereas on the 63cm it is 230mm. To add to this, as you go up the size curve, head angle becomes slacker and seat angle becomes steeper. This is to allow the optimal bike fit, ensuring the same performance and feel through the size curve. Thus, depending on size, compared to the Oltre the head tube is 20mm - 40mm longer, the reach is 6mm - 9mm shorter and the chainstays are longer for a broader wheelbase. All of this is aimed at a more forgiving ride.
Fortunately, Bianchi did not have to change the rim brake Infinito CV frame too much to create the disc bike. Frame modifications to allow for brake forces and mounts have only added 40g to the frame weight. Post mounts are used front and rear with the front brake hose routed through the fork. As one would expect, all other cables and houses run internally and Bianchi has done an exceptional job to make the exits look as integrated and unobtrusive as possible.
The rear axle spacing is 135mm and uses a 12mm thru axle with a removable QR system. The extra width, and move to disc brakes, allows greater clearance for up to 28mm wide tyres which further adds to the on-road comfort. The frame is mechanical and electronic groupset ready, future-proofing your purchase should you later wish to change things up
Its interesting to see that unlike other manufacturers who chase comfort, Bianchi has opted against the use of a thinner 27.2mm seatpost and have gone for a 31.6mm instead. Usually smaller diameter posts provide some flex which reduces road chatter through your backside. Bianchi must have been very confident in their technology and geometry changes and, as my experience proved, this has paid off. Other frame details include aero tubing, a tapered head tube, Pressfit 30 bottom bracket, and UTSS (Ultra Thin Seat Stay) inspired BAT (Bianchi Active Technology) seat stays.
