Author Ronin SL Gravel Bike Grey 54 cm

The Shimano GRX 1x12 drivetrain provides wide gear range and crisp shifting on climbs and descents alike. Paired with Mavic Allroad CL wheels and Panaracer Gravel King SK 700x40c tires, it grips confidently and rolls fast on gravel or asphalt.

Every component – from Ritchey cockpit parts to the Prologo Scratch M5 AGX saddle – has been chosen to enhance comfort and reliability. The Ronin SL delivers the perfect mix of classic steel feel and modern performance, ideal for long-distance riders who value both elegance and precision.
