Corima 45R Wheelset Review: A Balanced Performer for Diverse Cycling Needs

The Corima 45R wheelset stands out as a highly refined and versatile option for cyclists, striking an impressive balance between all-around road performance and long-distance comfort. Crafted in France, these wheels feature a 45mm profile, a generous 22mm internal rim width, and an innovative ratchet hub system, all contributing to exceptional aerodynamic stability, stiffness, and adaptability for various tire sizes. While not the lightest on the market, their premium construction and finely tuned ride characteristics provide a distinct advantage, making them a compelling choice for riders prioritizing craftsmanship and dynamic performance.

Corima's commitment to in-house manufacturing and rigorous testing ensures that the 45R wheelset delivers a superior feel, often absent in more mass-produced carbon alternatives. The wheelset's design incorporates a hooked rim, designated as 22TC, which guarantees compatibility with both tubeless and clincher tires, offering riders maximum flexibility. The 22mm internal width and 30mm external width are optimized for modern tire trends, ideally accommodating 28-30mm tires, though they can comfortably support widths from 25mm to 34mm, enhancing both comfort and versatility.

Aesthetically, the 45R embodies classic Corima elegance, showcasing a matte 3K carbon weave beneath a protective varnish. Understated black-on-black decals contribute to a clean and sophisticated profile. The wheels are built with 20 Sapim J-bend black spokes on both the front and rear, prioritizing simplicity, light weight, and ease of replacement. The use of steel spokes, in particular, is highlighted as a factor that significantly elevates the ride quality, offering a natural flex and responsiveness that some carbon alternatives might lack.

The newly engineered ratchet hub system features 36 teeth and a 10-degree engagement angle. Corima explains that its distinct star-like pattern on the external edge of the ratchet rings boosts stiffness and allows for better handling of higher torques compared to other designs. In practice, this translates to a crisp and immediate engagement, perfect for explosive sprints and challenging climbs, devoid of the common lag or soft pickup associated with some pawl systems.

Weighing in at approximately 1,454g with valves and rim tape, the 45R wheelset, despite being slightly heavier than its claimed 1,390g, remains competitive for a 45mm-deep wheelset within its price category. Setting up the wheels for tubeless use proved straightforward, facilitated by the pre-installed rim tape, supplied valves, and necessary tools. During testing, various 30mm tubeless tires were run at pressures between 60-65psi, demonstrating excellent reliability without any issues of burping or air loss, even on demanding terrain.

Out on the road, the 45R wheels live up to their billing as versatile performers. The mid-depth profile offers noticeable aerodynamic advantages at speed while maintaining exceptional stability in strong crosswinds, effectively minimizing buffeting and enhancing rider confidence. The responsive ratchet hub and relatively low rotational mass ensure brisk acceleration, making the wheels feel solid and efficient during out-of-the-saddle efforts, without any undue harshness. Corima's carbon layup successfully balances stiffness with compliance, making these wheels highly effective for climbing. The muted, yet mechanically distinct, freehub sound adds to the overall premium feel, distinguishing it from overly loud counterparts.

The Corima 45R wheelset, priced at £1,399, navigates a highly competitive segment of the market. While alternatives such as Ere Research's Genus II CL45 and the Reserve 40|44 wheelset offer similar specifications, the 45R differentiates itself through its handmade French craftsmanship and a unique aesthetic. Its ride quality, characterized by a lively and confident feel, consistently impressed during trials across varied landscapes, including challenging climbs and rough descents. The wheels maintained their integrity, remaining true and responsive, reinforcing their durability and robust construction. The consistent high spoke tension and smooth hubs further underscore their quality. Ultimately, the Corima 45R is a top-tier all-rounder, offering an excellent blend of speed, comfort, and reliability for discerning cyclists.
