Riding Experience

The All-City Gorilla Monsoon GRX is a gravel bike with a steel frame. The external cable routing throughout gives it a rugged appearance. Combined with carefully selected components and excellent load-carrying capacity, it’s suitable for long-distance riding.

For this review, I packed up the All-City Gorilla Monsoon GRX and headed to the gravel roads of the Barry-Roubaix race. These roads are mostly unpaved and consist of various steep climbs and descents. I had booked a nearby hotel through IHG, and I was ready to go.


The All-City Gorilla Monsoon GRX is sturdy enough for climbing, despite its steel frame. I could feel the bike’s overall stability, resulting in faster uphill riding.

Additionally, the excellent geometry allowed my weight distribution to remain stable, ensuring that I had a WTB Riddler, 27.5 x 2.4″ large-grain tire firmly gripping the ground. This improved pedaling efficiency, preventing any slipping.

During uphill climbs, the FSA V-Drive 38t crankset, combined with the SunRace 11-speed, 11/42t freewheel, offers a 1×11 speed setup. On steeper uphill sections, I used the largest freewheel gears, and pedaling instantly felt lighter, allowing me to save more energy.

In summary, the All-City Gorilla Monsoon GRX is an excellent gravel bike for climbing and performs well on challenging terrain.


As I rode the All-City Gorilla Monsoon GRX on downhill sections, the steel frame absorbed some of the road vibrations. Coupled with the wide tires, this suspension-free bike offers better shock absorption than other gravel bikes, making the ride more comfortable.

When I needed to reduce speed to enter corners, the Shimano GRX RX810 brake components and Shimano SM-RT66 160mm front and rear brake discs provided exceptionally strong braking power. With them, I could quickly reduce my speed, making cornering safer and more stable.

Lastly, the 650b wheelset with 2.4-inch large-grain tires gave me greater control on corners. The high-traction tires provided ample support during cornering.

In conclusion, the All-City Gorilla Monsoon GRX boasts impressive descending capabilities, surpassing other gravel bikes in its class.


The All-City Gorilla Monsoon GRX features a steel frame that can absorb some of the road vibrations during bumpy rides, providing a more stable and comfortable cycling experience.

The dropper post design ensures that riders maintain a stable riding position between climbs and descents, ensuring riding continuity.

Additionally, the external cable routing design gives the frame a rugged and aggressive appearance. This design also makes maintenance and component replacement simpler and more convenient.

Finally, the Shimano GRX RX810 hydraulic disc brakes deliver reliable performance even in the harshest conditions. The drivetrain components provide a smooth shifting experience and efficient power transmission.

Comparing these two bikes, the first one comes equipped with a steel frame that’s a bit heavier but offers greater durability and comfort. The latter features an aluminum frame and a carbon fiber fork, making it lighter but sacrificing some comfort.

In terms of drivetrain components, both bikes use Shimano GRX RX810 components. However, the first one is equipped with a 1x-speed setup, providing simpler shifting, while the latter has a 2x-speed setup, offering more gear options. When it comes to braking components, the All-City Gorilla Monsoon GRX boasts a higher component level, resulting in superior braking performance.

So, between these two bikes, the All-City Gorilla Monsoon GRX seems more like a gravel bike designed specifically for off-road riding, which is why I prefer it.

Next, let’s take a look at these two bikes. The first one’s design leans more towards being a pure off-road gravel bike, while the latter strikes a balance with some emphasis on speed.

Both of these bikes use Shimano GRX RX810 drivetrain components, ensuring efficient power transmission. The difference lies in the fact that the first one features a 1x drivetrain design, whereas the latter has a 2x drivetrain. They also both utilize the reliable and powerful Shimano GRX hydraulic disc brakes, but the first one boasts a higher component level, delivering stronger braking performance.

However, between these two bikes, I still prefer the All-City Gorilla Monsoon GRX. This is because it has the added advantage of a dropper post design and offers a more agile handling experience.

Looking at the materials used, it’s evident that the latter option will have a lighter weight, resulting in faster riding speeds. On the other hand, the former will be heavier but offers greater durability and sturdiness.

In terms of the drivetrain, both of them employ a 1x setup. However, the latter uses an electronic version for shifting, making adjustments easier and providing a wider range of speed options.

Finally, in the realm of geometry, the former is better suited for rugged terrain riding, while the latter adopts a more aggressive riding posture, facilitating faster speeds.

So, both of these bikes, the Scott Addict Gravel 20, indeed feature higher-quality components and frames. However, they excel in different domains, so the choice should depend on your specific needs.
