The Bontrager Betasso RSL GX TLR 28" Gravel Tire offers ultra-aggressive performance for grip and durability on changing and loose surfaces.
The RSL GX Construction features a robust 60 TPI casing with all-round puncture protection on the tire sides and under the tread, while the gravel-specific dual compound mix with a harder tread enables high speeds on the straights and provides plenty of cornering bite thanks to medium-density shoulder lugs.
