About the Cannondale Topstone, a gravel road bike for enjoying all types of terrain in Hiroshima.
Hiroshima City, where Grumpy's store is located, is in a superb location with mountains, rivers, and the sea close to the city, allowing for immediate enjoyment of various activities.
It's a great spot where you can reach various places by bike, using your own legs, without needing a car.
Riverside cycling stretching north to south, trail riding through the mountains, and long rides enjoying island views.
Hiroshima offers a fantastic environment where you can easily enjoy yourself without much effort.



Bicycles are available in optimal models for various uses. Of course, having a bike for every purpose is ideal, but it's also true that there are issues with money, space, or family approval that can be troublesome.
In such cases, a "gravel road bike" is highly recommended.
It's an all-rounder that handles various terrains and road conditions well, and its character changes dramatically just by swapping tires.
That's why we recommend Cannondale's Topstone series. They are lightweight, ride well, and are enjoyable without fuss.
The Topstone comes in two main types: carbon and aluminum models.

Cannondale Topstone Carbon 4
Price: 320,000 yen
Color: Olive Green
Available sizes:
XS 1 unit (Height 147cm - 165cm)
S 1 unit (Height 160cm - 175cm)
M 1 unit (Height 170cm - 185cm)
The carbon model features Kingpin suspension, which offers high vibration absorption and a comfortable ride. Although it appears fully rigid at first glance, the rear part of the frame flexes to absorb shocks, allowing it to glide smoothly even on somewhat rough roads.
This model boasts such high off-road performance that once you get used to riding the Topstone, you'll even be able to tackle trail rides.

Cannondale Topstone Carbon 4 is also introduced in this YouTube video.
Additionally, among the complete Topstone Carbon bike lineup, the one featuring Cannondale's unique Lefty front fork is this.
The front suspension design contributes to a supremely comfortable ride.
We have a size S test ride model of this bike in store, so please come and try it out.

And the other lineup is the Topstone aluminum model.

The aluminum model is also characterized by its high customizability, with numerous braze-ons for attaching rear racks and fenders.
This is the model that overseas tourists were riding when I was cycling near Miyajima before; it's a gravel road bike that can handle long rides with heavy loads.
Since the aluminum model is lightweight and highly customizable, I think it's best to enjoy it as a complete bike at first, then gradually change parts to experience the differences.
And the most cost-effective aluminum model is the Topstone 4.

While Cannondale TopStone complete bikes have different model names depending on the parts configured, the framesets are basically the same.
If you want to fully enjoy a gravel road bike, I highly recommend starting with a lower initial investment and gradually upgrading parts!
As parts improve in performance, it feels like a completely different ride, allowing you to fully enjoy the differences in ride quality through customization.
Also, since there are parts available in a wide range of colors, customizing your Topstone to your personal specifications is also an option.
For initial parts upgrades, these manufacturers are recommended:

GROWTAC EQUAL Flat Mount Brakes
Price: 33,220 yen
A brake set with a wide color lineup and excellent maintainability.
By replacing the brake set on your TopStone 4, you can increase braking power and add originality.

If you're thinking of customizing your wheels, GROWTAC's new product, the EQUAL Disc Hub, is also recommended, with a wide range of colors. A front and rear hub set costs 43,780 yen.
If you're looking for a complete wheel set, the price will vary depending on the rims and spokes, so please inquire for details.

If you want to paint your frame your favorite color, Grumpy can do it. Single-color frame paint starts from 22,000 yen.
Change the color of the "Cannondale" logo, create a gradient color, or choose any color you like.
