All-City Gorilla Monsoon Demo Bike: Steel GRX Gravel 650b 55cm Hotberry

The All-City Gorilla Monsoon is your ultimate adventure-ready gravel bike for conquering rugged trails, bikepacking expeditions, and everything in between. Engineered for cross-country adventures and backcountry exploration, this versatile steel steed combines durability with elegance to deliver smooth performance whether you’re tackling doubletrack or gravel grinds. With seven frame sizes—including a first-time 43cm option—it’s designed to fit riders from 4’11” up to 6’6”, ensuring a tailored ride no matter your stature.

Crafted from All-City’s renowned 612 Select chromoly steel tubing and featuring TIG-welded construction, this bike balances strength and compliance for all-day comfort on demanding terrain. Its bi-plane crown fork not only adds style but also accommodates Surly 8- and 24-Pack racks for loaded touring or bikepacking trips. Cleared for 27.5×2.4” tires (or 700c x42mm) with ample mud clearance, it handles loose gravel paths or muddy singletrack with ease. Flat-mount disc brakes deliver reliable stopping power across varied conditions.

The build kit shines with premium components: Shimano GRX RX810 shifters/brakes paired with a SunRace 11-42t cassette provide crisp shifting over technical climbs and descents. WTB Riddler tires grip diverse surfaces while FSA V-Drive cranks ensure efficient power transfer. Thoughtful touches include three water-bottle mounts and integrated rack/fender mounts—perfect for multi-day excursions or commuting adventures.

This test model has been ridden minimally for evaluation purposes only; minor wear appears on tires/brakes/rotors while the frame remains pristine in “like-new” condition—a smart choice for riders seeking adventure without compromising on quality or style.
