Bianchi Oltre XR4 Disc Module - Tavalozza

The Bianchi Oltre XR4 Disc Module - Tavalozza is a frameset built for riders who want to arrive at a race — or a long training block — having lost nothing to the road. It is Bianchi's flagship aero road platform, and the thinking behind it is straightforward: aerodynamic performance and structural efficiency should not come at the cost of the rider's legs over four or five hours. Whether you're contesting a crit or grinding through a hilly sportive, the Oltre XR4 is engineered to keep you working, not recovering.

The frame uses Bianchi's Oltre XR4 Premium Carbon, with aero tube profiles developed to reduce drag across the kind of variable, imperfect riding positions that real-world racing demands — not just the static posture a wind tunnel favours. Disc brake integration runs through flat-mount callipers and 12mm thru-axles front and rear, delivering consistent braking response regardless of conditions. Tyre clearance extends to 30mm, which means you can run wider rubber for comfort, grip, or both — without compromising the frame's aero intent. This is a race bike that has quietly absorbed the lessons of the last decade of road cycling.

What makes this module worth attention is the Tavalozza designation. Bianchi's Tavalozza programme — Italian for "palette" — is the brand's custom colour offering, and the variant here is finished in CK16 Celeste with Iron Glossy accents. It is unmistakably Bianchi, but the Iron Glossy trim gives it a harder edge than a standard catalogue build. If you are commissioning a frameset around which to build a serious machine, the finish should match the intent — and this one does, without needing to shout about it.

Design Benefits

1. Countervail Vibration Cancellation: Countervail is a co-developed viscoelastic carbon fibre material integrated directly into the frame's layup — not added on top of it. It is designed to absorb high-frequency road vibration before it reaches the rider, with Bianchi claiming a measurable reduction in vibration energy transmitted through the chassis. Over a long day in the saddle on rough tarmac, that is the kind of detail that separates arriving tired from arriving depleted.
2. Aero Carbon Architecture with Real-World Intent: The Oltre XR4's tube shapes are developed with aerodynamic drag reduction as a primary objective, but the geometry and profile work is intended to function across the range of positions a rider actually holds during a race or hard ride — not just a single optimised angle. This is aero design built for racing conditions, not wind tunnel theatre.
3. Disc and Thru-Axle Integration: Flat-mount disc callipers and 12mm thru-axles at both ends give the braking system structural rigidity and consistent lever feel that rim setups cannot match in wet or variable conditions. The thru-axle standard also contributes to front-end stiffness — something you notice immediately when sprinting out of a corner or holding a line in a crosswind.
4. 30mm Tyre Clearance: Running wider rubber is no longer a concession — it is a performance choice. The Oltre XR4's clearance for up to 30mm tyres means you can optimise for surface conditions, reduce rolling resistance on rougher roads, or simply carry more confidence on descents. The frame accommodates that choice without asking you to sacrifice its aero profile to get there.
5. Tavalozza Custom Finish: The CK16 Celeste and Iron Glossy finish on this module is not a stock option — it comes from Bianchi's Tavalozza programme, which exists specifically for riders who want a frame that reflects a considered build rather than a catalogue selection. The depth of finish here is consistent with a bespoke project, and the combination of Bianchi's signature celeste with the Iron Glossy accent is a pairing that reads as both heritage and intent.

Final Take

The Oltre XR4 Disc Module is built for the rider who builds deliberately — someone constructing a road bike around a clear set of demands rather than accepting a complete build's compromises. The Tavalozza CK16 Celeste finish means that bike will also look exactly as considered as it rides. This is a frameset for serious road racers and dedicated enthusiasts who want a platform that asks nothing of them over the long haul.
