AVONA Callis 32 SRAM Rival XPLR 13S Gravel Bike

The next-generation Avona Callis rolls on 32" wheels. Measured with the Virtual Elevation method on a bumpy gravel road, the bigger wheel saved Avona between 8 and 16 W at 35 km/h depending on terrain and tyre, more than any other upgrade they could find.
