Otso Cycles | Waheela C Carbon Gravel Frameset

Three bikes in one. One frame for almost anything.

The Otso Waheela C is a carbon gravel frameset built to race fast, explore farther, and adapt to whatever terrain lies ahead.

Proven at demanding gravel events and long-distance bikepacking races, the Waheela C combines massive tire clearance, adjustable geometry, and a surprisingly compliant EPS-molded carbon frame. Its versatile platform can be configured for fast gravel racing, rough backcountry routes, or fully loaded endurance adventures without losing its responsive character.

Key Features

• Massive Tire Clearance
Fits 700C, 650B, and most 29 x 2.1-inch tires for everything from fast gravel to rough and technical terrain.

• Adjustable Tuning Chip Geometry
Otso’s patented Tuning Chip adjusts the wheelbase by up to 20 mm and the bottom bracket height by 4 mm for quicker handling or greater stability.

• Compliant Carbon Construction
EPS-molded carbon and bowed seat stays help absorb vibration and trail chatter while preserving efficient power transfer.

• Race and Adventure Versatility
Compatible with rigid or short-travel suspension forks, internal dropper posts, 1x or 2x drivetrains, and cargo mounting systems.
