The geometry adopts a design typical of an entry-level road bike, balancing riding performance and control.

The head tube length is somewhat long, allowing for an upright riding position with extra stack height.

There's also plenty of tire clearance, allowing for conversion to tires up to 28mm (700c) in actual measurement.

The cables are internally routed. This design is expected to reduce maintenance risks and improve aerodynamics.

With specifications perfect for daily use and activities like cycling, and a balanced feel, it's highly recommended as a first road bike.

About the Fenix SLA DISC Parts Configuration

The basic specifications adopt Shimano Tiagra (2×10 speed).

The specs are more than adequate for an entry-level grade.

It's a nice touch that the crank also uses Tiagra.

The brakes also adopt Shimano Tiagra flat-mount hydraulic disc brakes.

Additionally, Shimano wheels are adopted. While not lightweight wheels, they are durable and long-lasting.

Vittoria ZAFFIRO (700×25c) tires are used. This area could be upgraded.

The Selle Italia Model X saddle is adopted, which is a rather good saddle choice for an OEM part.

Overall, the parts configuration is quite good! You can fully enjoy it in its stock condition, and it's also great for customizing later to suit your style.

Test Ride Impressions of Fenix SLA DISC

My impression after a test ride was that it's an aluminum road bike with no peculiar habits.

It offers a solid pedaling feel while providing a relaxed position and high maneuverability suited for beginners.

It has sufficient riding performance for both daily use and cycling. It's a model that truly helps you understand what a road bike is.

While it might be a bit unexciting for those seeking cutting-edge performance, it's a perfect model for anyone looking to enjoy road biking for the first time!

Summary of 2025.RIDLEY Fenix SLA DISC

Entry-level frame with a good balance of lightness and rigidity
Full Shimano Tiagra adoption
The price for the 2025 model is exceptional

For a disc aluminum road bike with Tiagra, the market average is around 200,000 yen for good cost performance, but the Fenix SLA DISC is under 150,000 yen.

Considering that Ridley was not a brand that could be purchased at this price point, it's frankly a surprising price.

RIDLEY is a brand that prohibits online sales due to manufacturer's policy, so it's not like everyone can easily buy it, but I expect it to sell out quickly.

Therefore, if you are considering purchasing a road bike, please do so as soon as possible!
