Brevard RSL SE
Brevard, North Carolina — the jumping-off point for classic rugged trails featuring loose and mixed conditions with challenging rocks, roots, and technical descents. Keeping in line with their namesake, Bontrager Gunnison is made for tackling loose, rocky, and technical terrain.
Versatile tech tread pattern
Brevard features a versatile tech-focused tread pattern for grip and durability in loose and mixed conditions.
RSL SE construction
A robust 60TPI casing features squarewoven nylon puncture protection from bead-to-bead, additional sidewall inserts, and butyl apex inserts for superior flat resistance from cuts, slashes, and pinch flats.
Trail triple-compound
A medium-firm center rubber provides braking and climbing traction while soft shoulder rubber adds cornering confidence. An ultra-supportive base helps maintain a fast-rolling tire.
Go tubeless
A properly set up tubeless system lets you run lower tire pressure for better traction, added confidence, and a smoother, faster ride.
30-Day Unconditional Guarantee
If for any reason you're not satisfied with a Bontrager or Trek aftermarket purchase, return the item, along with the original sales receipt to the original place of purchase within 30 days for an exchange or refund. Think of it as a 30-day test ride.
