colnago mountainbike Colnago C72 Red AXS Bike

The Colnago C72 Red AXS Bike is the latest evolution of the most storied modular carbon lineage in professional cycling. From the C40's Paris-Roubaix victory in the early 1990s through the C68 and now the C72, Colnago has hand-built each generation of its flagship road bike at its Cambiago facility outside Milan — seven carbon parts bonded, banded, and finished entirely in Italy. That tradition isn't marketing. It's the reason the C72 rides the way it does: with a coherence and refined quality that full monocoque construction rarely achieves at the junction points.

The C72 is lighter than the C68 — the size-485 frame weighs 895g unpainted, 30g less than its predecessor — and the right build reaches 6.8kg complete. But the weight reduction isn't the headline. Colnago's phrase for the C72 is "perfectly composed," which is accurate: the bike is responsive without being twitchy, and comfortable over long distance without going soft. An updated geometry with an increased stack-to-reach ratio means it can be configured for a more relaxed, endurance-oriented position without losing the racing DNA the C Series has always carried. On descents, it's planted. On climbs, it gives back what you put in.

This build leaves nothing on the table. A complete SRAM Red AXS E1 groupset handles shifting and braking — Colnago's top-spec wireless electronic build — and the crankset includes an integrated power meter. That's not a common inclusion at any price point. ENVE SES 4.5 carbon wheels roll front and rear, a deep-section rim designed to balance aerodynamic advantage with enough versatility for climbing. The new Colnago CC.02 integrated cockpit connects bar and stem in a single unit — 15 grams lighter than the CC.01 it replaces, with a revised curve that supports a more aggressive, controlled position on lower drops. The build is finished with Pirelli P Zero Race TLR tires at 700x28, tubeless-ready, on a frame that accepts up to 35mm.

Design Benefits

1. Modular carbon construction: Seven individual frame parts are produced in smaller, more precise moulds, then hand-bonded and carbon-banded at Colnago's Cambiago facility. Smaller moulds allow tighter control over carbon quality and layup at every section — including the junctions, which on most frames are where ride quality and structural integrity compromise each other. The C72 turns those junctions into a signature.
2. Panel gap design language: Where previous C Series bikes treated frame junctions as structural necessity, the C72 makes them a deliberate design statement. Each joint is aligned with panel gap precision — a visual vocabulary borrowed from industrial design that signals the care behind the construction. Up close, this is what separates the C72 from bikes that simply claim Italian craftsmanship.
3. SRAM Red AXS E1 with integrated power meter: The top tier of SRAM's wireless electronic groupset, with no cables to route and no mechanical actuation to wear. The power meter is built into the crankset — not an add-on, not an upgrade. Day one on this bike is day one with data.
4. ENVE SES 4.5 wheels: Deep-section carbon rims optimized for a balance between aerodynamic performance and climbing efficiency. Paired with Pirelli P Zero Race TLR tubeless tires, the rolling setup is fast, flat-resistant, and compliant enough to benefit from the C72's improved vibration absorption.
5. Integrated storage compartment: The forward bottle cage is designed to lift off, revealing a hidden storage compartment beneath. No bolt-on bag, no frame strap. Clean lines on a bike that's meant to look as considered as it is engineered.
6. Blockchain ownership registration: Each C72 includes registration on Colnago's blockchain system — ownership recorded on a secure, accessible ledger. Practical for resale, authentication, service documentation, and theft recovery.

Final Take

The C72 is for the rider who has arrived at a specific place in their cycling life — where the bike needs to perform at the highest level, last for decades, and not make concessions on craft. This is a hand-built race machine from the house that introduced carbon frames to professional cycling, and it shows in every joint. The Red AXS build adds ENVE wheels and a power-meter-equipped SRAM Red groupset to a frame that earns its place at $15,750. For the rider who rides seriously and intends to keep riding seriously, this is the C Series.
