Bicycle Derailleur Hanger Extension Goat Link Extender Conversion Adaptor
Have problems after installing yr monster MTB wide ratio cassette?
This will solve your problem!
The derailleur hanger extension is a unique adapter that offsets the position of your derailleur to make it possible to run a wide-range mountain bike style big cassette. It is an ideal solution for riders looking to convert their road, gravel, cyclocross, or commuter drivetrain bike to attain the simplicity and reduced weight of a single front chainring but without giving up the gear range of a double speed.
It is also great for riders with double chainring bikes that want lower gearing for those ultra steep climbs. It does not compromise the shifting in the smaller cogs of the cassette but yet it enables the derailleur to work with large as a 40T/42T /46T /50T Wide Ratio cassette.
Extend yr rear derailleur hanger for those people using Short /Medium cage to use wide ratio Shimano / Sram / SunRace cassette
By using this adapter, short cage will become medium cage. Medium cage become long cage
You need this if u r using Shimano saint/Zee or other Sram Downhill short cage rear derailleur
