We’re all stuck at home dreaming about how are cancelled gravel races may have gone, at least we’ve still got socially isolated outdoor rides and Zwift keeping us going. That, and new bike releases. Otso’s flagship gravel bike, the Waheela C, just got some fresh paint and an upgraded build spec for 2020.

The Waheela C is available as a frame, fork, and headset for $2,550, or as a complete bike with Shimano GRX for $3,600. More info at OtsoCycles.com.
