If your frame has no braze-on boss for the front derailleur you want to run, this adapter clamps around the seat tube and gives you one.

Highlights

  • Clamps onto a 34.9mm seat tube
  • Adds a braze-on mount for a braze-on-style front derailleur
  • Silver finish

Compatibility & fit

Fits a 34.9mm seat tube. SCV's listing doesn't confirm shim sizes for smaller tube diameters on this SKU — if your seat tube is narrower than 34.9mm, check with Problem Solvers or the Tune workshop before ordering.

Cover here follows Problem Solvers' standard manufacturing-defect warranty for accessories and small parts, on top of your rights under Australian Consumer Law. For warranty support, return the product to Tune Cycles and we'll manage the claim with Problem Solvers' Australian distributor.
