Surly Krampus Steel Hardtail MTB – Rugged Trail Ready

The Surly Krampus is the trailblazing plus-sized mountain bike that redefined off-road capability when it first hit the scene—and continues to dominate today’s rugged terrain. Built for conquering anything from loose scree slopes to root-strewn singletracks, this powerhouse rolls on massive 29 x 3” tires that devour obstacles while maintaining speed on open trails. Engineered specifically for riders seeking stability without sacrificing agility, its versatile design makes it ideal for plus-sized enthusiasts tackling everything from weekend epics to enduro-style adventures.

At its core lies Surly’s legendary Chromoly steel frame—a blend of durability and ride-smoothing compliance that’s been refined over decades. The double-butted main triangle combines strength with lightweight efficiency, while trumpet-flared tubes enhance stiffness under hard pedaling. Paired with an equally robust steel fork featuring internal dropper post routing compatibility, this bike offers seamless integration of modern trail tech while maintaining classic steel reliability.

The Krampus’ Gnot-Boost rear hub system stands out by offering unmatched versatility—easily adapting between Boost 148x12mm thru-axles, standard 142x12mm setups, or even traditional quick-release hubs via its adjustable dropouts. This smart engineering ensures you’re never boxed into one wheel configuration while maintaining precise tire clearance geometry tailored for chunky rubber up to three inches wide.

Key Components:
– Drivetrain: Shimano M6100 Deore SGS rear derailleur paired with an MT511 cassette provides crisp shifting across steep climbs or high-speed descents
– Stopping Power: Tektro HD-M275 hydraulic disc brakes deliver confident control on technical descents
– Tire Tech: Tubeless-ready Surly Dirt Wizard tires grip loose surfaces effortlessly thanks to their aggressive tread pattern
– Wheelset: WTB ST i40 rims laced to Novatec hubs form a sturdy yet lightweight foundation

Size Matters:
This bike’s geometry scales perfectly across four sizes:
| Size | Rider Height Range | Trail Advantage |
|——|——————–|————————————|
| SM | 5’4” – 5’8” | Agile handling on XC singletracks |
| MD | 5’7” – 6’ | Balanced all-day trail performance|
| LG |5’11” -6’3” | Dominant on steep mountain descents|
| XL |6’2” -6’6” | Unmatched stability for endurance rides|

While competitors often prioritize alloy frames that sacrifice comfort or rigid Boost-only hubs limiting upgrade options, the Krampus combines responsive steel construction (~32 lbs medium) with adaptable spacing systems—all wrapped in Surly’s signature rugged build quality guaranteed by TIG welding and E.D.-coated protection against trail wear-and-tear. Whether you’re carving berms at your local park or exploring remote backcountry lines loaded down with gear, this bike’s blend of strength and versatility ensures every ride feels like an adventure worth repeating.
