The Growler Jr 24 is a scaled down version of the popular hardtail from Rocky Mountain Bikes. Like its big brother, it’s a progressive hardtail shredding machine.
Progressive geometry and plenty of kid friendly features

Enduro geometry on a hardtail?

The redesigned Rocky Mountain Growler 50 is a hard-charging hardtail with the attitude of an enduro bike. This aggressive bicycle lives for high speeds and...
Aggressive geometry
Built to last
Killer tires

Sluggish in tight spaces

Rocky brings modern hardtail geometry at an entry-level price with the 1000 USD Growler 20...
Modern geometry with 64° head angle
Well-built aluminum frame with Boost 148, tapered headtube, BSA BB
Shared frame across all Growler models
29x2.6" tires with clearance for more
WTB Trail Boss tires are surprisingly capable
Shimano MT201 brakes have good feel and modulation
780mm handlebar
WTB Volt saddle is a solid choice
Good climbing traction
Stable descending due to geometry and tires
Future-proof and upgrade-friendly frame
Awful hard plastic grips
No clutch derailleur – loud drivetrain, chain drops under load
Basic Suntour fork is overdamped, non-adjustable, blow-off issues on big hits
Square-taper crank flexes under load
Altus drivetrain doesn't shift well under load
Brake power lackluster compared to higher-end systems
Resin-only rotors and Centerlock hubs limit upgrade ease
No dropper post
Seatpost may be too short for some riders (steep STA)
Wish for size-specific chainstays
