Keep riding!
Flat tires and mechanical issues have no power to end your ride, not when you're prepared with a well-stocked Tool Roll.
-tube pocket easily fits up to 700x35 tube with all three pockets available, and I'm currently riding with a 27.5" x 2.35" tube in mine by leaving one pocket unused(to allow the roll room to fold properly).
-two tool pockets have plenty of room for your particular blend of tools/flat repair/tater tots
-cobra buckle locks your roll securely in place, extra long strap is provided for cut-to-fit versatility
-1000D Cordura or XPac exterior, high-vis interior
-12"w x 10"h when fully open, pockets are 5" deep and 4" wide
