Shimano GRX-Used Complete Gravel Groupset w/ Shifters/Brakes/Derailleur/Cassette – ST_RX Series

Upgrade your gravel rig with confidence using this pre-owned Shimano GRX 800 1×11-speed groupset package—perfect for endurance cyclists tackling everything from remote backroads to urban commutes on mixed terrain. This complete system includes shifters/brake levers (ST-RX810), brake calipers (BR-RX810), rear derailleur (RD-RX812), and a rugged Shimano Deore XT CS-M8000 cassette, delivering professional-grade performance at an accessible price point.

Designed for adventure riders seeking reliability without compromise, these ST-RX810 hydraulic disc brake levers integrate seamless 1×11-speed shifting via Shimano’s Shadow RD+ derailleur technology, ensuring crisp gear transitions even during aggressive off-road riding. The GRX 800 rear derailleur handles cassettes up to 42 teeth with its wide-range design, giving you the versatility to conquer steep climbs or maintain speed on fast descents. Paired with the Deore XT cassette—known for its durability across thousands of miles—the system offers a smooth powerband ideal for long-distance gravel events or daily commutes over rough surfaces.

This package retains its near-mint functionality despite prior use (rated 8/10), showing only minor cosmetic signs of wear after careful maintenance by previous owners. At just 1696 grams total, it strikes an impressive balance between lightweight efficiency and robust construction compared to heavier entry-level gravel groupsets.
