Welcome to the official ICAN blog.
For cyclists, upgrading wheels is one of the most effective investments that can dramatically change riding performance. However, the market is flooded with numerous options, and the "under £1,000 (approx. 160,000-200,000 yen)" price range is arguably the most fiercely contested battleground for balancing performance and cost.
This time, based on a detailed review by the YouTube channel "Jourdain Coleman," we will thoroughly dissect ICAN's latest masterpiece, the **"FL40/50 Max"** carbon wheelset. With an astonishing price point of 100,000 yen, this product combines professional-level precision and lightweight performance, leading to its reputation as offering "the highest level of cost-performance." We will explain the reasons why, along with technical data.

1. First Impressions and Design: Premium Finish That Satisfies Ownership Desires
From the moment you unbox it, ICAN's dedication to quality is evident. The wheels are carefully protected with thick foam, and tubeless valves, rim tape, and a factory Quality Control (QC) sheet are included. This QC sheet details spoke tension and runout measurements, demonstrating a serious approach to engineering.
The most distinctive feature of the **"FL40/50 Max"** is its rim profile:
Front: 40mm depth (emphasizing control and resistance to crosswinds)
Rear: 50mm depth (emphasizing propulsion from aerodynamics)
This combination of different depths for the front and rear is an optimal solution for maintaining stable handling in windy conditions while maximizing aerodynamic performance during high-speed cruising. Additionally, the iridescent logo on the rim changes its appearance depending on the light, creating a sophisticated, high-end feel that is not overly flashy.

2. Spec Verification: "Lightness" and "Width" Exceeding Stated Values
While many brands tend to have actual weights heavier than their stated weights, the ICAN FL40/50 Max achieved surprising results.
Astonishing Lightweight Performance
Actual Front Weight: 617g
Actual Rear Weight: 734g
Total Weight: 1,351g (without rim tape and valves)
This weight is significantly lower than ICAN's stated value (around 1,410g). Achieving a weight in the mid-1,300s with a deep rim profile of 40/50mm makes it a formidable weapon in all scenarios, from hill climbs to flat races.
Adoption of Wide Rims
To optimize for the recent trend of 25c to 28c or wider tires, a wide design with an internal width of 23mm has been adopted. Actual measurements show the rear at 23.28-23.36mm and the front at 23.34-23.43mm, ensuring ample volume even beyond the stated values. This increases tire air volume, improving ride comfort, reducing rolling resistance, and enhancing stability in corners.

3. Component Reliability: Uncompromising Part Selection
Reliable components are generously used for the heart and framework of the wheels.
Spokes: Sapim CX-Ray Made of stainless steel, these are very light and boast high strength, earning them the title of "gold standard in spokes." The straight-pull method directly transmits power from the hub to the rim.
Hubs: ICAN 28S Hub Designed specifically for centerlock disc brakes. The front hub rotates incredibly smoothly, with no unpleasant bearing drag whatsoever. The rear hub's freebody is Shimano-compatible by default, but can be swapped for SRAM XDR. The freehub's ratchet sound is powerful, producing a pleasing sound that announces the rider's presence to those around them.

4. Precision Test: Perfect Factory Setup
Jourdain Coleman used a dedicated truing stand and dial indicators to verify precision down to the micron. The results were astounding.
Radial and Lateral Runout
Radial Runout (Roundness): Front 0.15mm / Rear 0.16mm
Lateral Trueness: Front 0.15mm / Rear 0.16mm
The average deviation was only 0.18mm. This is the second-best record among the nine major wheelsets he has tested to date, surpassed only by ICAN's other model, the "Aero 50." This extremely high level of precision for a factory-fresh wheel is comparable to a wheel after professional mechanic adjustment.
Spoke Tension and Dishing
The spoke tension variation was perfectly within the acceptable range of 5%. Furthermore, the wheel's dishing was perfect, proving that it can be accurately mounted to the frame without any deviation of even 1mm.

5. Overall Review: Why Should You Choose the "FL40/50 Max"?
The ICAN FL40/50 Max is not just an "inexpensive carbon wheel." It is a **"racing product" that combines precise engineering, lightweight materials, and outstanding quality control.**
This wheel is ideal for:
Those who want top-class lightweight performance while staying within budget.
All-rounders who want to minimize the effects of crosswinds while enjoying aerodynamic benefits.
Those seeking the latest tubeless riding experience with 23mm wide rims.
With its lightness, so exceptional that it draws jokes like "lighter than my hope of maintaining FTP during winter training," and build quality that rivals high-end brands, the ICAN FL40/50 Max will be the smartest choice to elevate your cycling life to the next level.
