Terra Gravel Road

The Terra is a lightweight road bike with a wild sense of adventure. The Terra is fast and fun, with a spirit that wills you to get off the beaten track. The OSD triple-butted 6061 aircraft grade aluminum bike frame is equally adept at adventures as commutes. Designed with venturesome riders in mind; those who may want to take the shortcut along the towpath; hammer the bridleways instead of the tarmac. A low bottom bracket cultivates your confidence through the technical sections of whatever route you choose to point the Terra lightweight road bike; the full carbon tapered fork matching steering capabilities to actualize a competence rarely associated with a drop barred machine.

Shimano’s 105 groupset supplies reliable shifting during these forays with Tektro’s Spyre disc brakes providing dependable and precise braking in situations when you need it the most. Fulcrum’s resilient Racing Sport Disc wheels will power along through any terrain. Rack and mudguard mounts allow you to take your detours further, add panniers for a weekend getaway or a long distance bike-packing trip. The Terra is a lightweight road bike that rewards your eagerness to roam.
