Author Ronin SL Gravel Bike Grey 50 cm

The Author Ronin SL is a high-end gravel bike designed for riders who value smoothness, precision, and durability. Its triple-butted Reynolds 700c steel frame absorbs road vibrations and delivers outstanding comfort during long-distance rides.

The Author Carbon fork ensures sharp steering and extra stiffness, while the Shimano GRX 1x12 drivetrain offers a perfect balance between wide gear range and simplicity.

Mavic Allroad CL 700C wheels paired with Panaracer Gravel King SK 700x40c tires provide confident traction both on tarmac and gravel. Premium Ritchey components and a Prologo Scratch M5 AGX saddle ensure long-lasting comfort.

This bike combines the endurance spirit of a road bike with off-road freedom – ready for adventure, training, or touring.
