"It has been a little over a year since Onza released the Grava. In that time, it seems to have dropped off the face of the earth. It isn't on their website anymore, and the only place we can seem to find it is online retailers like Bike Tires Direct. We reached out to Onza regarding the confusion around the Grava tire. We were informed that the brand had to discontinue the tire due to copyright issues with another brand."
"But, specifically, they are best known for their mountain bike tires. The brand dates back to the 1990s, with iconic tires like the Porcupine putting them on the map. But Onza is breaking away, just a bit, from their mountain biking roots to introduce a complete gravel tire lineup. The Allegra X will be a family of six tires with a naming structure that is so easy to follow, even I can figure out what each is for."
Onza Tires is a European brand historically known for mountain bike tires dating to the 1990s, including the Porcupine. The brand previously released the Grava gravel tire but discontinued it amid copyright issues and limited availability. Onza introduced the Allegra X gravel lineup consisting of six models labeled X1 through X6. The naming scheme directly indicates tread aggressiveness: higher numbers add more bite and traction while lower numbers favor faster rolling. The Allegra X family aims to simplify gravel tire choice by making intended use and aggressiveness clear through the model numbering.
