The Bianchi Infinito Shimano 105 12-speed brings an all-rounder approach to road cycling, blending responsive road performance with comfort over long distances and the freedom to explore varied surfaces. Designed for training rides, full days in the saddle and changing routes, the latest Infinito platform focuses on versatility without losing its road-bike character.

The Bianchi Infinito frame features internal cable routing and an integrated storage compartment in the down tube, designed to carry small tools or a wind jacket. It uses Flat Mount 140/160 disc fittings, a PressFit 86.5×41 mm bottom bracket and a 12×142 mm rear thru-axle. SRAM UDH compatibility and tyre clearance up to ETRTO 622-40 offer flexibility for different setups.

Its mechanical Shimano 105 12-speed drivetrain includes ST-R7120 shifters, an RD-R7100 rear derailleur, an FD-R7100 front derailleur and an FC-R7100 Hollowtech 2 crankset with 50x34T chainrings. The Shimano 105 CS-R7100 11-34T cassette provides a useful range for rolling roads and climbs. Shimano BR-R7170 hydraulic disc brakes, paired with 160 mm Shimano SM-RT54 rotors, provide controlled stopping on varied routes.

Bianchi B30R alloy wheels feature a 30 mm rim profile and 23 mm internal width. They come with Pirelli P7 Sport 35-622 tyres, rated at 60 TPI, reinforcing the bike's comfort-focused versatility. An AL6061 Bianchi stem and Bianchi Compact AL6061 handlebar shape the cockpit. The Bianchi Infinito carbon seatpost combines an aero-flex design with Countervail technology to help reduce vibration, while the 260x150 mm Bianchi Manganese Rail saddle completes the contact points.

Available in Celeste Metallico / Logo CK16 and Rosso Rubino / Logo Avorio, this Infinito build is ready to accompany fitness rides, challenging climbs and long road adventures. It balances a well-defined mechanical groupset with practical details that make everyday rides and ambitious routes equally appealing.
