THE ULTIMATE ALL-AROUND GRAVEL BIKE
Fun things happen when a bike is designed to be as versatile as its rider. Waheela C is a carbon-framed drop bar bike with an adjustable geometry, unrivaled ride quality, suspension-corrected geometry for a suspension fork, and enormous tire clearance for 700c x 54mm, 650b x 54mm, or 29" x 2.1" tires. It also has extra frame and fork mounting points for bottles and racks, easily accessible internal cable routing options, compatibility for 1x or 2x electronic or mechanical drivetrains, and the ability to run a dropper post. When the same bike can be found racing Unbound, riding Tour Divide, hopping CX barriers, loaded up for weekend overnighters, and cruising weekly group rides, the performance-first versatility speaks for itself.
Call it three bikes in one. Call it a quiver killer. Call it the ultimate all-around gravel bike.
