The Bianchi Infinito Pro 105 Di2 Bike is the entry point to what is, as of 2026, one of the most significantly updated platforms in Bianchi's lineup. The Infinito Pro's new carbon frame and fork were developed as a fully integrated system — a complete redesign that delivers 12 watts of aerodynamic improvement over the previous generation while also raising the stack height for endurance comfort and lengthening the chainstays for stability. The frame accommodates tires up to 700x40 and includes a hidden down tube compartment for a multi-tool or wind jacket. All of that is here, at $5,200, with Shimano 105 Di2 electronic shifting.

The Countervail Vibration Cancelling System in the seatpost is the same on every Infinito Pro regardless of build level — viscoelastic material bonded into a full carbon aero-flex seatpost that absorbs vertical road shock at the contact point between rider and bike while the frame stays stiff for power transfer. The zero offset is intentional: it optimizes hip angle to support breathing efficiency and pedaling mechanics over long efforts. This is not a component that changes between trim levels. Whether you buy this bike or the Force AXS version above it, you get the same Countervail seatpost, the same frame, the same fork, and the same 700x40 tire clearance.

What the 105 Di2 version trades relative to the higher build is in the groupset and cockpit. The drivetrain is Shimano 105 Di2 — R7150 derailleurs front and rear, R7170 hydraulic disc brakes, R7170 shift-brake levers. Electronic Di2 shifting is precise, consistent, and low maintenance regardless of tier; 105 Di2 is the same Di2 platform as Ultegra and Dura-Ace, using the same wired electronic architecture with a battery integrated into the seatpost. The chainring setup is 50/34 with a Shimano 105 R7101 11-36 cassette, giving a solid range for varied terrain and sustained climbing. There is no integrated power meter at this build level.

The wheels are the Bianchi B 49R — the companion to the RC 49R that comes on the Force AXS version. Both share the same 49mm depth and 25mm internal rim width, and both are tubeless ready. The B 49R uses J-bend spokes rather than the straight-pull Superwing spokes of the RC 49R, and comes in at 1,575g versus the lighter RC 49R — a difference that matters less on the long endurance rides this bike is designed for than it would on a pure climbing or crit machine. The tires are Pirelli P Zero Road TLR in 700x35, a reliable tubeless road tire at this width. The stem and handlebar are alloy — a Bianchi alloy stem and Aero Compact alloy bar — which reflects the price point while still providing a solid, proportional front end across the six available sizes.

The bike ships in two colorways: Sparkling Black and Petrol Green / Celeste. Both run the same full size range from 47 to 59cm.

Design Benefits

  1. Same Infinito Pro 2026 frame and Countervail seatpost as higher builds: The fully integrated carbon frame, internal storage, 700x40 tire clearance, 12W aero improvement, and Countervail vibration-cancelling seatpost are all present — regardless of build level.
  2. Shimano 105 Di2 electronic shifting: The same Di2 platform architecture as Ultegra and Dura-Ace, providing precise, consistent electronic shifting with a wired system and seatpost-integrated battery. Reliable across varied conditions and long miles.
  3. 11-36 cassette for genuine climbing range: The 50/34 chainrings with 11-36 cassette provide a wide gear range appropriate for mixed-terrain endurance rides and rolling hills without sacrificing top-end development.
  4. Bianchi B 49R carbon wheels: Same 49mm depth and 25mm internal width as the RC 49R on higher builds — tubeless ready with a wheel profile sized to complement the frame's aerodynamics at a more accessible price point.
  5. 700x35 tubeless tires / 700x40 max clearance: Pirelli P Zero Road TLR in 700x35 provides all-road versatility; the frame's 40mm clearance leaves room to go wider for rougher surfaces.
  6. Internal down tube storage: Onboard compartment for a multi-tool or compact wind jacket — the same practical feature found across the entire 2026 Infinito Pro range.

Final Take

The Bianchi Infinito Pro 105 Di2 is the most accessible way into the 2026 Infinito Pro platform — the same frame, the same Countervail seatpost, the same internal storage, and the same all-road capability, with Shimano 105 Di2 electronic shifting instead of SRAM Force AXS. At $5,200 for a fully electronic carbon endurance bike with 49mm carbon wheels and 35mm tubeless tires, the tradeoffs from the higher build are clear and reasonable. The bike that matters most here is the frame, and the frame is the same.

Not great at cooling
Size: Queen (2 Count), Color: Original White (Cooling)
Each pillow cover has 2 sides, one marked for cooling, and the other a different fabric. The cooling side is about the same effectiveness as having a silk or satin pillow cover. It's only cool when you first touch it. The cooling side doesn't seem to absorb or wick moisture, so if you are sweaty - it keeps the moisture in place. You'll definitely want a regular pillow case over the pillow cover. In fact, if you suffer from night sweats, the non-cooling side is actually more comfortable. The pillow fill is ample, and simple to squish around for more support for your neck, etc. Think bean bag. But it will retain your impression after use. I find I need to do as I did when I had down pillows - give it a few good shakes in the morning when I make the bed to get it evened out for the coming night. In all, it is a well-made and comfortable pillow to sleep on, but it does not excel in cooling.

excellent pillows i bought two sets!!
Size: Firm Queen (2 Count), Color: Original White (Cooling)
I ordered these for my son who has neck issues and has gone through so many pillows trying to find one that he liked. They’re heavy, so i was worried that they might be “too” heavy to be able to sleep on comfortably, so I ordered a second set, one firmer than the other (just in case) and gave him a set for Xmas and he loved the first set so much without even trying the less firm ones.He also needs the cooling factor and these offered that, too. They are filled with pieces of memory foam (tons of it) and each pillow can be modified by removing some of the foam. The covers are beautiful, high quality fabric with a zipper so ts easy to remove or replace the foam pieces. The size is perfect and they keep their shape. I kept the second set i ordered rather than returning them and i love the pillows. I actually modified two by removing some of the foam pieces. I kept the foam pieces in a zippered pillow protector and i can always adjust mine when or if i need to. 1000% love these.

The Perfect Firm Pillow l
Size: Queen (1 Count), Color: Original White (Cooling)
It is everything it claims to be, cool, comfortable and strong. I got this for my husband first, he loves it and then got one for my son, he uses it to support his knees and has been sleeping much better since then. They both needed a firm pillow that is not super soft, firm but not achy. Finally found the perfect one.

It works! Quality pillow.
Size: Standard (1 Count), Color: Original White (Cooling)
This does actually provide a cooling effect, and it's very comfortable! The accompanying literature is helpful too. I believe this to be a quality pillow for the price.

Most comfortable pillow I’ve ever slept on
Size: Queen (1 Count), Color: Crescent White(cooling)
This is the most comfortable pillow I have ever slept on. It doesn't mash down like other pillows. Cradles my neck perfectly plus it’s cool. I broke my neck a couple of years ago and this pillow feels very good and comfortable. Definitely recommend to everyone. Ive used it since May and it’s retained its shape.
