First Ride: Rocky Mountain Pipeline 770 MSL

A quick ride on Rocky's new plus-size rig

Rocky Mountain was no latecomer to the plus-size game, announcing its purpose-built bikepacking model, the Sherpa, at Sea Otter last year. This time around, Rocky is launching another plus bike–one built for trail riding.

The new bike, which mates a carbon front triangle to an aluminum rear end, takes its name from the venerable Pipeline–Rocky’s original freeride machine–and has similar intentions: pedal up and then shred down. Those intentions are backed up by 150 millimeters of fork travel and 130 millimeters of rear-wheel squish. Boost axle spacing and a committed single-ring design help the Pipeline fit tires up to 3.25 inches wide. That’s a lot of rubber, so Rocky saved a bit of weight by speccing bolt-on axles.

The Pipeline takes geometry cues from Rocky Mountain’s 130-millimeter wagon-wheeler, the Instinct, and the Ride-9 chip system allows riders to adjust the geometry and suspension rate to suit their riding style and terrain.
