Bontrager GR1 Team Issue Gravel Tire

Overview

"The Bontrager GR-1 Team Issue tires blew away my expectations"

"The tight, small knobs of the GR1 create a fast-rolling tire with consistent grip on hardpack dirt and fine gravel."

"A brilliant all-round gravel tyre"

"And the supple casing provides burp free riding at low pressure that’s surprisingly resistant to cuts and gashes"
