Betasso Product Overview
Betasso is an aggressive gravel tire with a robust RSL GX construction that is built using bead-to-bead plus sub-tread puncture protection so you can explore way off the beaten path worry free.
"Usually with gravel tires, fast on pavement means you’ll be missing out off-road, but the Betasso gripped well in our humidity-slicked conditions, followed up by bone-dry late summer dust."
