What is GT GRADE's unique technology? A thorough explanation of the frame structure and ride feel.

Why is GT a gravel pioneer? Explaining its history and background.

GT, an American brand leading the MTB industry, was one of the earliest major brands to approach the "gravel road" category.

At that time, Japan was in the midst of a road bike boom. Naturally, many brands were focusing on road bikes, but GT opted for a strategy that exclusively featured drop-bar models for gravel roads.

In other words, it can be said that GT is a pioneering presence in the domestic gravel road category.

This is the "GRADE ALLOY COMP," an aluminum frame model from GT's gravel road series, "GRADE."

 

The secret of Triple Triangle & Floating Stay

GT bicycle aluminum gravel road bike Grade Alloy Comp

This is what GT is known for: "Triple Triangle Frame". It features a unique frame shape where the seat stays are welded to the top tube, a design that has been highly acclaimed in the MTB field for a long time.

  • And, the "Floating Stay (a method where the seat stay and seat tube are not welded)" offers a boldly flexible ride without sacrificing rigidity.

 

These designs significantly reduce impacts from the ground.

This not only reduces physical burden during long rides but also greatly impacts stability and performance on dirt courses, making it an excellent technology for a gravel bike.

The geometry adopts a well-balanced and versatile design.

Compared to popular road bikes, the wheelbase is longer and the center of gravity is lower. However, considering the amount of luggage for bikepacking and riding on rough terrain, it's designed to incorporate the necessary riding performance for a gravel road while not sacrificing the nimble feel on paved roads.

 

Perfect for camping rides! Excellent expandability with numerous bolt mounts.

About the GRADE ALLOY COMP parts configuration

Main Component (Shimano GRX)

The basic specification uses Shimano GRX400 (2x10 speed).

Rear 11-34T, Front 48/32T, wide ratio specification◎

For gravel bikes, a single front chainring is popular. This is because a simpler setup has advantages in avoiding chain and shifting problems.

However, for rides with many paved roads, you might want higher speeds. Also, for long rides in Japan which always include hill climbs, a double front chainring with lighter gears has its advantages.

 

Braking performance (hydraulic disc brakes)

The brakes are flat-mount hydraulic disc brakes. The wheel attachment is a 12mm thru-axle, which is a perfect modern specification.

 

Tires (WTB Riddler 700×37c)

The tires are WTB Riddler (700×37c).

The tread pattern, with its small, scattered knobs, provides excellent grip on gravel courses while also offering nimble performance on paved roads.

Both the wheels and tires are tubeless-ready models. It's a nice touch that you can immediately convert to a tubeless setup if you have sealant.

By the way, the tire clearance allows for tires up to 42c. For those who want to enjoy dirt courses even more, this is a great option!

Many other brands also offer aluminum gravel road bikes, and some models are even more reasonably priced than this one.

However, there are few models that incorporate the history of a brand that quickly approached gravel road bikes and the technology that allows for unique characteristics through its original molding.

This gravel road bike properly delivers on what's expected of a gravel road bike: "a balance of on-road and off-road riding performance" and "load capacity and expandability."

I believe it's a high-quality aluminum gravel road bike that is easy for beginners to handle and will satisfy experienced riders!
