Description
"Wolf Tooth Components" is a Minneapolis-based group of hardcore cyclists who create unique cycling components. All items are designed independently and manufactured in the USA.
The RoadLinkâ„¢ derailleur hanger extension is a unique patented device that offsets the position of the road derailleur to allow for the use of a wide range of mountain bike style cassettes.
In other words, this revolutionary part allows you to increase your rear gear range up to 40 tons without changing your road components.
It is the ideal solution for riders looking to modify their road, gravel, cyclocross, or commuter drivetrain bicycles to achieve front single simplicity and weight savings. It is also ideal for riders on double-chain bikes who desire lower gearing for ultra-steep mountaineering.
Optimized for use with 11-36t and 11-40t cassettes with 10 or 11 speeds, it is recommended for use with Wolf Tooth's 40 tooth GC cassette extender and drop stop chainrings.
Installation is as simple as inserting it between the derailleur hanger and the derailleur.
It is optimized for Shimano 10 or 11 speed road derailleurs and shifters, but also works well with SRAM and Campy. Can be used with single or double chainrings.
