The CHIRU SAVAGE reinvents full-suspension mountain biking with a radical approach: a hand-brushed Grade 9 titanium front triangle paired with a UD carbon rear triangle, creating a 2500-gram frame that combines the best of both materials. Designed in France for trail and all-mountain enthusiasts, this 29" frame promises comfort, precision, and versatility across all alpine terrain.

Technical Summary: A Material Pairing Designed for Performance

The Chiru Savage is built on a single-pivot kinematic with progressive linkage offering 120 to 150 mm of rear travel (depending on Fox Float X or X2 shock), compatible with 140 to 160 mm forks. The front triangle in 3Al/2.5V Grade 9 titanium is hydro-formed, ovalized, and triple-butted for maximum lateral rigidity while absorbing vertical impacts. The rear triangle in Medium Modulus carbon provides reactivity and pedaling dynamics, while the aluminum linkage with Enduro Bearing ensures durability and smoothness. An integrated flip-chip allows geometry adjustment (head angle, bottom bracket height) between trail or enduro configuration.

Technical Highlights

• Triple-butted Grade 9 top tube: ovalized in the horizontal plane to flex vertically, dissipating impact energy while preserving lateral rigidity.
• CNC-machined T47 x 73 mm bottom bracket: threaded, oversized center diameter, for superior rigidity and reliable installation.
• ZS56/44 tapered semi-integrated headtube: CNC machining with variable thickness, reinforced ends, compatible with tapered fork for precise steering.
• Optimized internal routing: rear brake hose integrated in downtube (maximum protection, gentle bending radius), internal/external cabling for derailleur (including Di2), Ø6 mm passage for rear lighting.
• One-piece postmount brake attachment: integrated frame design ensuring perfect alignment of 160 mm caliper.
• Radical quality control: each tube inspected ultrasonically before welding to eliminate any internal cracks.
• Laser engraving and hand-brushed finish: clean and timeless aesthetics, engraved Chiru logo.

Geometry and Standards

• Progressive mountain geometry: 64° head angle, 76.5° seat angle, compact 435 mm chainstays, generous yet manageable reach.
• Wheels and tires: 29" with clearance up to 2.5" width, Boost 148 x 12 mm rear axle.
• Boost 1x12-speed drivetrain: compatible with Shimano XT (mechanical/Di2) and SRAM GX/X01/XX1 (mechanical/AXS), single chainring 30T max, 53 mm chainline.
• Dropper seatpost: Ø31.6 mm internal, up to 175 mm travel (Fox Transfer Factory included as option), internal routing, sloping geometry for great freedom of movement.
• Sizes S / M / L: suited for riders 5'2" to 6'2".

Chiru Philosophy: Durability and Bikepacking

The Savage is built to last. Grade 9 titanium resists impacts and corrosion, while UD carbon maintains its mechanical properties over time. Velcro luggage attachments, 1 bottle cage mount, rear lighting cable passage: the Savage is bikepacking-ready, built for alpine expeditions as much as for committed bike park sessions. A frame for demanding riders who refuse to choose between comfort, light weight, and robustness.
