Surly Karate Monkey Mountain Bike: Built for Trail Mastery

The Surly Karate Monkey is engineered for riders seeking a versatile steel steed that conquers rugged trails with confidence. This all-mountain machine combines Surly’s signature durability with progressive geometry, making it ideal for technical descents and all-day adventures. Crafted from 100% 4130 chromoly steel, the frame features a double-butted main triangle and trumpet-flared tubes for a responsive yet smooth ride. Its Gnot-Boost rear dropout system offers flexible drivetrain compatibility—whether you’re running 142mm, 148mm, or 135mm hubs—while internal dropper post routing keeps your setup clean and sleek.

Key Features:
Trail-Optimized Design: Clearance for 29×2.55″ or 27.5×3″ tires (tubeless-ready) ensures grip on loose terrain.
Custom Build Flexibility: Choose from multiple wheel sizes (27.5″) and drivetrain setups, including Shimano Deore M6100 components for crisp shifting and braking power.
Lightweight Performance: Weighing just 31 lbs (medium), this bike balances strength with agility for climbs and high-speed corners.

The build kit shines with reliable parts: Tektro hydraulic brakes for control, WTB ST i40 rims paired with Surly’s Dirt Wizard tires for traction, and a Salsa Rustler handlebar for confident handling. The frame’s snow mold white finish adds a touch of style without sacrificing ruggedness.
