Designed to tackle the most demanding technical and mountainous terrains, the Chiru Highlander frame embodies titanium excellence in the service of adventure MTB and bikepacking. Specifically developed for the legendary Highland Trail 550 in Scotland (885 km and 16,000 m of elevation gain), this Grade 9 titanium (3Al/2.5V) hardtail combines lightness, robustness, and exceptional comfort for long distances. With its 120 mm fork travel and capacity to accommodate tires up to 29 × 2.6" or 27.5 × 2.8", the Highlander transforms every adventure into a memorable epic.

Technical Highlights

Bikepacking Ready

The Highlander is a true Swiss Army knife for adventure. It features multiple mounting points: 3 bottle cage mounts (3 × 750 ml), bosses for bolt-on frame bag, top tube bag, rear rack, and fenders. The full internal routing ensures optimal cable protection (derailleur, brake hoses, dropper post, rear light cable) and clean aesthetics.

Geometry and Sizes

Available in 4 sizes (S, M, L, XL), the Highlander fits riders from 164 to 196 cm. Each size features identical 435 mm chainstays for consistent agility, while the progressive reach (395 to 471 mm) and stack (632 to 645 mm) guarantee a balanced position between efficiency and comfort. The wheelbase varies from 1108 to 1192 mm depending on size, offering stability on descents and liveliness on accelerations.

Drivetrain and Compatibility

Compatible with 1×12-speed mechanical, Di2, or AXS electronic drivetrains, the Highlander accepts a chainring up to 34 teeth maximum with a standard Boost chainline of 53 mm. The design allows great equipment versatility to adapt to all terrains.

Chiru Heritage

Founded by Pierre-Arnaud Le Magnan, French engineer and ultra-endurance athlete, Chiru Bikes has established itself since 2009 as a global reference for titanium frames for bikepacking and adventure. The "Dream, Design, Craft, Ride" philosophy guides every development: frames are tested in real conditions on the most demanding routes before being marketed. The Highlander symbolizes this approach, the fruit of years of experience on global ultra-races.
