We're thrilled to finally have the new Rivendell Bicycle Works OM-1 Rear Derailleur in stock. This beautifully crafted, jewel-like component is a refreshing reminder that mechanical ingenuity still has a place in modern cycling.
The OM-1 uses Rivendell's long-developed Opposite-Movement (OM) design, a concept they spent more than eight years refining before partnering with Microshift to bring it to life. The result is a derailleur that is mechanically robust, remarkably smooth in operation, and unlike anything else currently on the market.
Built for riders who appreciate thoughtful engineering and timeless functionality, the OM-1 is more than just a conversation piece—it's a dependable, high-performance derailleur designed to be used and enjoyed for years to come.

- Chain wrap capacity: 39T

Despite its classic appearance and rugged construction, the OM-1 is surprisingly light—lighter than the vast majority of derailleurs available today. Rivendell wasn't chasing weight savings, but excellent design has a way of producing elegant results.
Each derailleur comes packaged in Rivendell's signature information-packed box, complete with technical details, setup information, and a beautifully illustrated user guide.
For riders who appreciate durable, serviceable, and mechanically satisfying bicycle components, the Rivendell OM-1 is a welcome addition to the modern drivetrain landscape.
