This SRAM adaptor clamps a braze-on front derailleur to a 31.8mm seat tube, with wide spacing for SRAM's 47.5mm Wide chainline. It includes a Chainspotter stop; SRAM describes its chain spotters as protecting the frame and adjusting independently of the derailleur.

Highlights

  • Genuine SRAM front derailleur clamp adaptor
  • Wide spacing for a 47.5mm chainline
  • Clamps to a 31.8mm seat tube
  • Chainspotter stop included

Compatibility and fit

Use it on 2x set-ups built around SRAM's 47.5mm Wide chainline; SRAM lists that chainline for its Force and Rival eTap AXS Wide front derailleurs, which take braze-on or clamp mounting and 43/30T chainrings. For a standard chainline, SRAM lists a standard-spacing 31.8mm adaptor, and both come in 34.9mm too. Derailleur height and angle must be reset to SRAM's specification after fitting, so a workshop fit is a good idea.

This SRAM component is covered by SRAM’s warranty against defects in materials and workmanship; terms are set by SRAM. Wear and service items (chains, cassettes, brake pads, rotors, tape and seals) are normal maintenance parts.
