The Trail Boss SG1 builds on perfection with an aggressive tread pattern to match its width. Generous spacing between sizable knobs provides better traction in loose or wet conditions, while staying true to its fleet-footed heritage. Large, supportive side knobs dig deeeeeeep, whether youre leaning into a corner or grabbing a handful of brake. Most often used as a rear tire, the Trail Boss 2.4 also provides plentiful traction as a front tire on hardpack trails. SG1 puncture protection runs under the tread cap and has extended bead protection.
