Want a bigger climbing gear without a new derailleur? This extension moves a road rear derailleur down and back so it clears a wide-range, mountain bike style cassette.

Highlights

  • Extends the position of a road rear derailleur
  • Lets a road derailleur run a wide-range cassette
  • Super B Premium range

Before you buy

A bigger cassette also needs enough derailleur capacity and a longer chain. Check your derailleur's maximum cog and total capacity before fitting.

Compatibility & fit

For road rear derailleurs mounted on a conventional hanger. Super B doesn't publish a maximum cog size or a derailleur list. Prefer to leave it to us? Our workshop can fit it, size the chain and set up the gears.

Super B offers a limited lifetime warranty: under normal use, a tool with a defect in material or manufacture will be repaired or replaced. It doesn't cover normal wear, or damage from accident, abuse, neglect, modification or improper use. This cover is in addition to your rights under the Australian Consumer Law. Keep your proof of purchase. For warranty support, return the product to Tune Cycles and we'll manage the claim with Super B's Australian distributor.
