Aggressive geometry

Sluggish in tight spaces

Rocky brings modern hardtail geometry at an entry-level price with the 1000 USD Growler 20...
Progressive 64° head angle at $1,000 price point
Aluminum frame shared with higher-tier models (Boost 148, tapered headtube, BSA BB)
29 x 2.6" tires with clearance for more
Predictable WTB Trail Boss tires with good cornering and climbing traction
Great Shimano MT201 brake lever feel with modulation
Solid saddle selection (WTB Volt 142mm)
Good geometry for descending, stable and capable
Affordable price with upgrade potential
Cheap hard plastic grips (awful)
Clutchless derailleur leads to noise and occasional chain drop
Square-taper crankset flexes under load
Basic Suntour fork overdamped with blow-off that can be unsettling
Resin-only rotors (Centerlock) inconvenient for upgrades
Altus drivetrain doesn't shift well under load
Brakes lack stopping power compared to higher-end systems
No dropper post; short seatpost on steeper STA
Stock tires not tubeless, need conversion
