Wolf Tooth Tanpan Derailleur Converter

With the popularity of multi-surface adventure rigs continuing to rise, the fine line between mountain and road continues to blur. More and more cyclists are pairing the drop bar geometry of a road bike with the expansive gear range of a mountain bike. Due to the modern appetite for one bike to do it all, the once frustrating incompatibility between road shifters and mountain rear derailleurs has been expelled from the cycling world thanks to the Wolf Tooth Tanpan derailleur converter.

The Tanpan brings the range and security of Shimano mountain rear derailleurs to Shimano-equipped drop-bar bicycles, by amplifying road shifter cable pull to allow for seamless communication with wider range mountain derailleurs. This is the perfect solution for riders looking to convert their road, gravel, cyclocross, or commuter bike to the simplicity and light weight of a single chainring, or anyone looking for an even lower gearing than a typical double ring crankset can provide. If used with a clutch-equipped Shadow+ rear derailleur, the Tanpan can also be credited with providing unparalleled chain security for Shimano road drivetrains.

The 17g Tanpan installs in moments, tucking neatly above the rear derailleur and an indexed barrel provides for quick and easy cable adjustment. Each Tanpan is CNC machined in the USA by Wolf Tooth and comes fitted with precision stainless steel hardware and a sealed cartridge bearing.

Compatibility:

• Compatible with most road, gravel and CX bikes.
• Important Note: If the rear derailleur cable is routed internally through the chainstay and exits at the end of the chainstay above the axle or past the axle out the very end, you will need to run full length cable housing.
  • You will have to route the full length housing so it exist from under the bottom bracket (most bikes have a removable cap there) and runs externally along the chainstay.
  • The reason for this is that the Tanpan barrel adjuster end sits too close to the frame for the internally routed cable to exit the frame and enter the Tanpan barrel adjuster
• Always adhere to manufacturer's published derailleur tooth capacity specifications.
  • 1.1mm diameter shift cable recommended and a new cable is always a good idea.
