WTB Trail Boss
Best versatile rear tire for aggressive trail riders seeking reliable traction.
This is the ultimate rear-wheel workhorse for riders who prioritize predictable braking and cornering confidence over pure speed. While the aggressive, blocky tread pattern adds a bit of rolling resistance on hardpack, the trade-off is a remarkably consistent grip that keeps you glued to the trail through technical descents.
