Why is the FL38 MAX so highly rated? A hands-on review
Welcome to the official ICAN blog.
In road cycling, wheels are one of the most crucial components, significantly impacting ride quality.
Among them, **ICAN "FL38 MAX"** stands out for its excellent balance of "lightness, stiffness, and reliability," earning high praise from many riders.
This article will provide a detailed, real-world review of the FL38 MAX, re-evaluating its capabilities.
Furthermore, in the latter half, we will briefly introduce its evolved model, the **"FL40 II."**
1. What makes the FL38 MAX so appealing? — A versatile wheel with excellent balance
The greatest feature of the FL38 MAX is its high level of completion, where "everything is just right."
Its 38mm rim depth excellently balances:
・Lightness for climbing
・Cruising performance on flat roads
In actual riding, the ease of initial acceleration and maintaining speed is very impressive, making it an "all-round wheel" suitable for any scenario.
It's an ideal choice for both "first-time carbon wheel users" and riders who "want one wheel to do it all."
2. Real-world Review: "Stiffness Balance" beyond mere lightness
What you feel when using the FL38 MAX is a "sense of stiffness" that goes beyond mere lightness.
The power you put into the pedals is efficiently converted into propulsion, and the response during acceleration is incredibly smooth.
Yet, it doesn't feel overly stiff, designed to prevent fatigue even on long rides.
Key impressive points include:
- Stability during out-of-saddle efforts
- Ease of holding lines during cornering
- Ease of maintaining speed while cruising
All of these demonstrate a high level of "design capability" that cannot be achieved by simple weight reduction alone.
3. Why ICAN continues to use "hooked rims"
In recent years, the use of hookless rims has increased in the road bike industry.
However, ICAN continues to use hooked rims even for the FL38 MAX.
The reason is clear:
It prioritizes "safety" and "freedom of tire choice."
While hookless rims have air pressure limitations and tire compatibility restrictions, hooked rims allow for a wider range of choices.
This design ensures safe use for everything from daily rides to long distances.
This "solidity" is one of the big attractions of the FL38 MAX.
4. The Great Value of Cost Performance
"How can such performance come at this price?"
This is a question many users ask.
As a manufacturer with its own factory, ICAN handles everything from development to production in-house.
This allows them to cut unnecessary intermediate costs and excessive marketing expenses, focusing resources on the product itself.
As a result, they can offer performance comparable to major brands at a more realistic price.
5. Proven Durability and Reliability
The FL38 MAX not only boasts excellent specs but also demonstrates high durability in real-world usage.
Many users rely on it for long rides and daily training, and its reliability is already proven.
It overturns the image of "carbon wheels being difficult to handle," offering a dependable choice.
6. And now, the Evolution — Introducing the FL40 II
Building upon the highly refined FL38 MAX, the **"FL40 II"** is an even more advanced model.
Key improvements include:
- Rim height optimized: 38mm → 40mm
- Further weight reduction through the latest layup technology
- Improved aerodynamic performance
The exquisite 40mm rim height achieves both
higher cruising performance and a lighter riding feel.
While the FL38 MAX is a "perfectly balanced model,"
the FL40 II can be described as a model that adds "further refinement" to that foundation.
7. Conclusion: FL38 MAX or FL40 II?
The FL38 MAX is still a highly accomplished wheel.
It's an undeniable choice, whether for your first carbon wheelset or for long-term use.
On the other hand, if you're seeking newer performance and lighter weight, the FL40 II is an attractive option.
- Balance-oriented / Proven track record → FL38 MAX
- Latest performance / Further weight reduction → FL40 II
Whichever you choose, your riding quality will undoubtedly improve significantly.
