Bianchi Infinito 105 Bike
Bianchi Infinito 105 Bike Info
Not every ride is a race, and not every road is smooth. The Bianchi Infinito 105 Bike is built around that reality — an endurance carbon road bike designed for long days across whatever terrain you find, with vibration-absorbing technology, generous tire clearance, and a geometry that keeps you comfortable when the hours stack up. Where Bianchi’s Oltre platform is optimized for speed, the Infinito is optimized for distance.
The name has been part of Bianchi’s lineup for years: “Infinito” means infinite in Italian, and the bike earns the name through a combination of design decisions aimed at reducing fatigue on long rides. The most significant is the Countervail technology integrated into the carbon seatpost. Countervail is a viscoelastic material developed by North Thin Ply Technology that is embedded into the carbon layup — when road vibration enters the frame, this material absorbs and converts the energy into heat rather than transmitting it to the rider’s hands and body. The result is measurably reduced vibration over long distances without adding weight or softening the structural integrity of the post. It’s the same technology Bianchi has used in their higher-end endurance bikes, carried down to this spec level.
The geometry makes the Infinito’s intent clear. Stack measurements run from 531mm (47cm) to 614.5mm (59cm) — considerably taller than an aero road bike at the same nominal size. Reach figures are correspondingly compact: 370mm to 384mm. The combination produces a more upright position that reduces strain on the lower back and neck during extended efforts. Chainstays measure 420mm across most sizes, slightly longer than a race bike, which adds stability and creates space for wider tires. The 73mm bottom bracket drop is lower than an aero platform, keeping the center of gravity stable when carrying a load or riding mixed terrain.
The tires tell the rest of the story. The Infinito 105 rolls on Pirelli P7 Sport 700x35 — a tire width more commonly associated with light gravel bikes than a carbon road bike at this price. The frame accepts up to 700x40, which means you can run anything from a 28mm road tire to a near-gravel 40mm casing without changing the bike. That flexibility makes the Infinito a genuinely all-road capable machine: ride your weekend group ride on 32mm road tires, load it up for a mixed-surface adventure on 38mm, or keep the stock 35s and enjoy what they provide on imperfect pavement. The Shimano 105 R7100 12-speed mechanical drivetrain runs a 50/34 compact front with an 11-34 cassette in the rear — a gear range built for climbing and varied terrain, not criterium sprinting.
Design Benefits
- Countervail vibration-dampening seatpost — The Bianchi Infinito seatpost integrates Countervail technology — a viscoelastic material embedded in the carbon layup that converts road vibration into heat rather than passing it through to the rider. On long rides over rough pavement, this has a cumulative effect: less fatigue in the hands, arms, and back. It’s not a marketing claim; it’s measurable, and it’s why Bianchi built it into the Infinito line’s defining component.
- Endurance geometry for all-day riding — The Infinito’s stack/reach ratios are designed for sustained comfort, not maximum aerodynamics. A 531mm stack on the 47cm and 614.5mm on the 59cm puts the rider in a position that distributes weight more evenly across the contact points — relieving the lower back and neck strain that limits riding time on more aggressive geometries.
- 700x35 tires with 700x40 clearance — Stock Pirelli P7 Sport 700x35 tires provide real-world comfort and grip on imperfect roads. The 700x40 frame clearance means riders can run anything from 28mm road tires to 40mm near-gravel setups, making the Infinito one of the most versatile bikes in the carbon road category at this price.
- Shimano 105 R7170 hydraulic disc brakes — Even at this spec and price, the Infinito ships with genuine hydraulic disc calipers. The modulation and all-weather stopping power hydraulic disc provides is particularly relevant for an endurance bike that will see rain, mixed terrain, and sustained descents. The 160mm Shimano MT54 rotors provide appropriate stopping force without the added weight of larger rotors.
- 50/34 compact drivetrain with wide-range cassette — The 50/34 front and 11-34 rear cassette combination reflects how this bike is intended to be ridden: varied terrain, long climbs, and rides where you want to be moving at the end. The 12-speed spacing keeps gear steps smooth whether you’re spinning at 80rpm on a long grade or pushing 95rpm on a fast descent.
- Bianchi-branded components throughout — The Infinito 105 ships with Bianchi’s own stem, handlebar, and saddle rather than third-party alternatives. The handlebar runs 80mm reach and 130mm drop — slightly more generous dimensions than a race-oriented compact bar, giving more hand positions for longer days in the saddle.
Final Take
The Bianchi Infinito 105 is a different bike than the Oltre Race 105 in a meaningful way — same brand, same price bracket, different purpose. If you ride mostly on imperfect roads, do long fondos, carry a light load, or want a bike that doesn’t exhaust you on the back half of a 100-mile ride, the Infinito’s endurance geometry, Countervail seatpost, and wide tire clearance give it a real advantage. The 105 drivetrain and hydraulic disc brakes deliver reliable performance without requiring an upgrade budget, and two strong colorway options — Burgundy Red/White and Metallic Celeste/CK16 — give it a look that holds up against bikes at twice the price.
