The Orbea Orca M35i is built around the responsive ride feel of a lightweight road bike. Orbea has focused on balancing low weight with the stiffness needed for efficient power transfer, creating a bike designed to respond quickly when accelerating, climbing or changing direction.
The OMR carbon frame uses monocoque construction, allowing Orbea to carefully control the structure and amount of material used throughout the frame. Instead of pursuing the lowest possible weight at the expense of ride quality, the Orca is designed to remain stiff where efficient power transfer matters while reducing unnecessary material elsewhere.
That approach is particularly useful when climbing, where low weight helps when accelerating and responding to changes in gradient, while sufficient frame stiffness helps make effective use of the power you're putting through the pedals. The lightweight construction also contributes to the Orca's agile handling when cornering or quickly changing pace.
The matching Orca OMR fork uses full carbon construction, including the steerer. A tapered design and 12mm thru-axle provide a secure connection between the fork and front wheel, contributing to accurate steering while keeping weight down at the front of the bike.
Shimano 105 Di2 provides electronic 2x12-speed shifting. R7150 front and rear derailleurs are paired with R7170 Di2 shifters, providing quick and precise gear changes with light lever inputs. This makes it easy to move through the gears as gradients and speeds change without requiring the mechanical cable operation of a conventional drivetrain.
A Shimano 105 50/34T chainset is combined with an 11-34T 12-speed cassette. The resulting range provides useful lower gearing for sustained and steeper climbs while retaining smaller steps between ratios to help you maintain a comfortable cadence on flatter and rolling roads.
Shimano R7170 hydraulic disc brakes provide consistent, easily controlled braking. Hydraulic operation offers good modulation with relatively little lever effort, helping you manage speed smoothly when descending, approaching corners or riding in changing conditions.
Oquo Road Performance RP35TEAM wheels are a notable upgrade on the M35i. Their performance-focused construction complements the Orca's emphasis on low weight and responsive riding, creating a wheel and frameset combination suited to climbing, accelerating and varied road routes.
They're paired with Vittoria Corsa N.EXT 29mm tyres with tubeless-ready construction. The relatively generous road tyre width provides a useful balance of rolling efficiency, grip and cushioning, while tubeless compatibility gives you the option to run lower pressures and can help seal smaller punctures when used with sealant.
A 27.2mm SP 0.2 carbon seatpost helps keep the overall build lightweight and can provide some compliance over rougher road surfaces. It uses 20mm of setback and is paired with a Fizik Aliante R5 saddle.
Internal cable routing contributes to the Orca's clean appearance, while the frame is also power meter compatible. This gives riders interested in structured training the option to add power measurement without changing the fundamental character of the bike.
With its OMR carbon frameset, Shimano 105 Di2 drivetrain, Oquo RP35TEAM wheels and Vittoria Corsa N.EXT tyres, the Orca M35i offers a well-rounded performance build. It's particularly suited to riders who enjoy climbing and responsive handling but still want a versatile road bike for sportives, fast recreational rides and longer days in the saddle.
