新家工業/アラヤ スポルティーフ ロードバイク ディアゴナール

[Clearance Sale!] From ARAYA, a Japanese brand that preserves traditional aesthetic forms, the sportive "DIA (Diagonale)"

The "randonneur" and "sportif" categories are similar to road bikes but distinct from them.

While road bikes have evolved with the goal of "riding fast," randonneurs are designed for the purpose of "seeing how far one can go on their own two feet." This entails long-term riding and dealing with various weather conditions, etc., situations not encountered on a single-day ride. To cope with these, a simple mechanism is required to avoid the risk of mechanical problems.

A sportif, like ARAYA's "DIA (Diagonale)," is a category that adds ease of use and nimbleness to the randonneur!

Nowadays, gravel bikes are often used for randonneuring, but if you're pursuing traditional aesthetic beauty, gravel bikes are not quite the same.

That said, there are few manufacturers offering randonneurs and sportifs at accessible prices, making models like the Diagonale quite rare!

Diagonale Frame Design

The Diagonale's frame uses 4130 chromoly tubing with double-butted construction. This results in a frame with excellent durability and vibration absorption.

The frame design incorporates a long wheelbase for straight-line stability, along with a slightly higher center of gravity for nimble pedaling.

This design isn't specialized for a particular use case, but rather offers a balanced approach, making it versatile for both daily use and long-distance rides.

Full fenders come standard, and rear rack mounts are also provided, keeping with the sportif's practical specifications.

The Diagonale adopts brake/shift integrated levers (STI levers) for modern operability, but it also retains the mounts for W-levers, allowing for customisation.

This is a welcome feature for users who appreciate traditional styles!

Another pleasing feature for users who pursue tradition is the adoption of a threaded stem.

It pairs well visually with the slender chromoly tubing, creating a classical and simple impression.

The chromoly front fork features a sleek design (minimal protrusions) to create a sense of unity with the frame. This meticulous specification pursues a simple aesthetic.

 

The Diagonale's frame balances traditional aesthetics with consideration for riding performance. I believe it's a frame that can incorporate classical style into daily life and touring activities!


Diagonale Parts Configuration (Specs)

新家工業/アラヤ スポルティーフ ロードバイク ディアゴナール

The basic specs feature SHIMANO Claris (2x8 speed).

Despite being a sportif, it features modern specifications like integrated brake/shift levers for improved riding performance.

The crankset features a compact 46-30T gear, a configuration mindful of Japan's mountainous terrain where long rides inevitably encounter climbs. The inclusion of a bash guard makes it well-suited for everyday use.

Furthermore, the crankset is from ARAYA's original "Touring Classics" series of components, which seems to pair well with the Diagonale's design.

Incidentally, I believe the Touring Classics series was created through collaborations with various parts manufacturers to produce parts that meet ARAYA's ideals!

It features Mars-shaped drop handlebars. The saddle is a highly cushioned model, suitable for long rides.

Both are from the Touring Classics series, and their design complements the Diagonale well.

The tires are 700x32c, striking a good balance between air volume and nimble performance. The side walls are the so-called "ame-kuro" (amber/black) tires, reminiscent of an older style.

And, the wheels use silver-based aluminum rims. The hubs are made by SHIMANO to minimize breakdown risk, while the rims are from the Touring Classics series.

From tires to wheels, ARAYA's original Touring Classics series components are used, reflecting a commitment to design.

The brakes are cantilever brakes, fitting for a sportif.

As an aside... ARAYA's official website refers to them as "cantilever brakes," and I was touched by their attention to detail.

Cantilever brakes offer less stopping power compared to modern brake standards, so if you're planning long rides, consider an upgrade! It might be a bit challenging to improve functionality while maintaining the design aesthetic, but it's worth it.

Equipped with sub-brake levers reminiscent of safety levers as standard. While sub-brake levers are often perceived as being for beginners, they are a valuable component for long-distance/long-term riders.

 

The parts configuration is a well-balanced blend of design and operability, mixing ARAYA's original "Touring Classics" components in a classical silver tone with modern SHIMANO components that prioritize durability, maintainability, and operability.

Personally, I'm in favor of dual control levers on a sportif, but what do you think?

Impressions of the Diagonale Test Ride

新家工業/アラヤ スポルティーフ ロードバイク ディアゴナール

Indeed, unlike road bikes, this sportif's ride quality makes you feel like you can "ride for a long time" rather than "ride fast."

While it may be inferior to a road bike, it offers a nimble feel characteristic of a sports bike, combined with a cushioned ride.

 

新家工業/アラヤ スポルティーフ ロードバイク ディアゴナール

Above all, the sense of security provided by the mudguards... and the ability to approach cargo carrying, which is difficult with road bikes! Excellent practicality!

 

Its performance is perfect for daily city use and leisurely long-distance cycling. As a drop-handle model available for just over 100,000 yen, it offers excellent value for money.

 

These days, ARAYA's traditional sportif from a Japanese brand seems to be a good match in terms of performance for users who want a cost-effective road bike.

 

It's worth noting that the braking power could be upgraded later, but that's a minor detail.


ARAYA Diagonale Summary

  • Chromoly frame with a balance of durability, comfort, and nimbleness
  • Parts configuration that blends a simple, classical aesthetic with modern performance
  • Excellent cost-performance for a drop-bar model available for just over 100,000 yen
  • Rare to find a traditional sportif as a mass-produced model

 

新家工業/アラヤ スポルティーフ ロードバイク ディアゴナール

The "Diagonale" is a touring model sportif designed for light and extended travel.

It features a classical appearance with SHIMANO Claris installed, enhancing its ease of handling.

 

In my personal opinion, this model feels more approachable than a road bike or gravel road bike, and I believe it's a traditional model that suits Japanese people perfectly!

At a list price of just over 100,000 yen, these specifications are a great value!

Please consider it.
