2013 Serfas Thunderbolt Tail Light – Unboxing and Review

Krest Tire Review by David Tate, Brand Ambassador 500 miles of southeastern U.S. singletrack riding is on the clock. Although the knobs on the rear tire are beginning to show a little erosion along the leading edges, these Serfas Krest tires are still hooking up and inspiring confidence no matter the trail conditions. Thanks Serfas!
