The Sarto Raso is an endurance aero all-road bike that seeks to redress the balance between speed and comfort, tipping it toward the latter while arming you with a bike built to blaze on any road surface. Think a slightly less than laser focus on pure pace, on a bike you can ride in comfort as you sail past your personal bests.

Designed and built from raw carbon fibre up to a rolling rig entirely within its HQ in Veneto, Italy, the Raso benefits from Sarto's decades of research and investment in composite materials and arrives with a beautifully smooth and stiff unidirectional carbon fibre construction. In fact, with its 125 N/m torsional stiffness index, the Raso is Sarto's stiffest bike yet. And that, combined with custom-formed tubes designed to meet the air at every angle and smooth transitions between sections, makes the Raso not only searingly fast out of the gate but stable in the wind and unnervingly easy to hold at high speeds.

And as we mentioned, all of that speed comes with comfort to spare. Sarto has spent years tuning its bikes to balance power with compliance to ensure a cushioned ride doesn't cost you watts. For the Raso, that means an innovative frame layup that prioritises comfort from the first fibre, design concepts like vibration-dampening seat stays, and room for up to 35mm tires to help you float over any road at speed.

At the cockpit, flared handlebar drops inspired by the all-road endurance community better align with the flow of the shoulders and arms for a more natural connection between rider and bike. It's the sort of touch that elevates the Raso amongst its peers and speaks to the thoughtful and authentic nature of its design. Naturally, the bike's clean lines are reflected in the cockpit's smartly integrated profile.

Unusually for an aero endurance bike, the Raso is available in custom measurements and a range of stock sizes. And from there, the world. From ombre fades to geometric patterns via simple single colours to completely custom designs, Sarto's in-house paint shop can take the personalisation of your dream ride to new heights.
