The invention relates to a rubber composition based on at least one elastomer comprising from 50 to 100 phr of one or more copolymers of butadiene and of vinylaromatic monomer, having a content of vinylaromatic units of between 0 and 5% by weight and a Tg within a range extending from -110°C to -70°C, a reinforcing filler, a crosslinking system and an optionally hydrogenated hydrocarbon-based resin, predominantly composed of units selected from the group consisting of cyclopentadiene, dicyclopentadiene, methylcyclopentadiene and mixtures thereof, said hydrocarbon-based resin having an average molecular weight Mz of less than 2000 g/mol and a glass transition temperature Tg expressed in °C such that Tg ≥ 80 –2*(%HA), where %HA represents the content of aromatic protons of said resin, the content of said hydrocarbon-based resin is within a range extending from 15 to 150 phr.
