Chromoly frame delivers solid ride and easy-to-handle geometry

Slender chromoly frame creates a tough and straightforward ride

The ARISE SG is a gravel road bike that uses chromoly material for both the frame and fork. It's a slender, orthodox steel frame that combines the toughness and ease of handling characteristic of an adventure bike.

The vibration absorption and durability inherent in chromoly make it a reliable companion for long rides and touring. This is why chromoly frames continue to be chosen for adventure riding and bikepacking around the world.

However, the ride of this bike is slightly different from the impression of a "soft steel road bike." Rather than the suppleness typical of a steel road bike, it has a solid, core-like ride. While not a light bike, it responds well to pedaling force, allowing you to handle both paved roads and forest trails effortlessly.

Unpretentious, orthodox gravel geometry

The ARISE SG's frame design employs an unpretentious, orthodox gravel geometry.

The head tube length is set to be slightly longer, as is typical for gravel road bikes, naturally leading to a more upright riding position. This design reduces physical strain during long rides and makes the bike easier to handle even when carrying luggage for touring.

Moreover, the center of gravity is designed to be midway between light acceleration and straight-line stability, offering a good balance that is easy to handle in the city and provides a sense of security on forest roads. It possesses a "straightforwardness" that allows it to be ridden without discomfort in any riding style.

Sliding dropouts change rear center and riding characteristics

A distinctive feature of the ARISE SG's frame design is the adoption of sliding dropouts.

This allows for adjustment of the rear center (chainstay length), thereby altering the bike's riding characteristics.

Setting a longer rear center extends the wheelbase, improving straight-line stability. This provides a reassuring ride for touring or bikepacking with luggage.

Conversely, setting a shorter rear center makes cornering more agile, balancing the bike for gravel riding and city use.

In other words, the ARISE SG not only leverages the benefits of chromoly material but also features a frame that allows for adjustment of riding characteristics through geometry and variable dropout structure.

It's not the type of bike that boasts extreme speed, but it has a broad capability that allows it to "perform above average" in any situation. This versatility is what makes this bike so appealing.

Simple yet practical gravel component configuration

1x11 speed drivetrain featuring SRAM APEX 1

The main components of the complete bike feature SRAM's gravel groupset, APEX 1.

The 1x11 speed setup, featuring a single front chainring and a wide-range rear cassette, is highly practical for gravel riding.

The front features a Bombtrack TAF19 aluminum crank (hollow spindle) with a 40T chainring. This crank combines rigidity and lightweight, efficiently converting pedaling power into propulsion.

The rear is paired with a wide cassette with a maximum of 42T, providing a gear range that can handle steep climbs and challenging inclines on forest roads.

With no front derailleur, operation is incredibly simple, and there are fewer chances of trouble, making it a drivetrain that's easy to handle in a wide range of situations, from paved roads to gravel and forest trails.

Brakes are a candidate for customization if considering touring specifications

The brakes are mechanical disc brakes from TEKTRO. High maintainability is a benefit of mechanical disc brakes, making them easier to deal with in case of trouble during touring or adventure use.

However, if you're planning long tours with a heavy load or want to further enhance downhill control, it might be worth considering an upgrade.

The ARISE SG offers a high degree of freedom as a custom base, so there's the enjoyment of upgrading the brake performance according to your usage.

Vee Tire Speedster for smooth on-road riding

The tires used are Vee Tire Speedster. XS to S sizes come with 27.5×1.50, and M to L sizes come with 700×40C, with the optimal wheel balance considered for each frame size.

The tread pattern is designed with low knobs, making it a gravel tire that rolls smoothly on paved roads. It adopts a balanced type of tire that ensures cruising performance on paved roads, as expected from a gravel road bike, while also being capable of handling gravel paths and forest roads.

The true value of ARISE SG is its "expandability"

The ARISE SG's greatest feature is its high expandability.

The frame is equipped with numerous braze-ons for attaching fenders, racks, top tube bags, additional cages, and more. This makes it highly adaptable for bikepacking and long-distance touring.

Furthermore, this bike features sliding dropouts.

This enables setting changes such as:

• Single-speed conversion
• Tire clearance adjustment
• Chainstay length adjustment

This highly flexible design allows it to be adjusted for quick-handling gravel riding or for stable touring. It would also suit a commuter setup, and it has the potential to transform into anything depending on customization.

Summary | A gravel road bike you can enjoy for a lifetime

Honestly, this bike might not be the type of model to be evaluated solely on its "ride feel."

The true appeal of the ARISE SG lies in its high expandability.

More than just a gravel road bike, its design also accounts for touring and bikepacking. In addition to numerous braze-ons throughout the frame, the stable geometry and the toughness of the chromoly frame allow for confident riding even when carrying luggage.

It's a versatile bike that can be used freely for everything from camping tours to long rides, without limiting its purpose.

And another interesting aspect of the ARISE SG is that it doesn't end with its complete bike configuration.

You can start riding it as a simple 1x setup, then add a rack for touring, or convert it to a flat-bar commuter bike. Utilizing the sliding dropouts, you can even turn it into a single speed, or in the future, add multiple front gears for a more road-oriented setup.

It's a bike that lets you imagine a future where, as you customize it to fit your lifestyle and how you enjoy riding, it becomes the bike you've had the longest.
