Wolf Tooth RoadLink Derailleur Hanger Extension – Derailleur Hanger Extender optimised for 11–36T to 11–40T Cassettes, Mounts to Standard Rear Derailleur Hanger, Made in USA

• Run wide-range cassettes by offsetting your road derailleur to use 11–36T and 11–40T while keeping small-cog shifting crisp; ideal for road, gravel, cyclocross, and commuting.
• Optimized around Shimano road geometry; best with a shimano rear derailleur. Works with 10- and 11-speed.
• Compatibility: single 11–34, 11–36, 11–40; doubles only when within GS (medium-cage) capacity. Not supported: 11–42, triple chainrings, or direct-mount frames.
• RoadLink mounts only to a standard rear derailleur hanger. It increases clearance for larger cassette cogs but does not increase derailleur capacity; results may vary by setup.
• Easily installed in minutes; stainless steel bolt included (8–10 Nm). CNC-machined 6061 aluminum, 17 g. Black. Made in USA.

The RoadLink derailleur hanger extension is a unique, patented device that offsets your road derailleur so you can run wide-range cassettes. It lets riders convert to a single front chainring without giving up range, and gives 2x riders lower gears for steep climbs. It preserves shifting in the smaller cogs while enabling use of cassettes up to 40T. Installation is quick—typically under five minutes. The RoadLink mounts only to a standard derailleur hanger. Important: RoadLink repositions the derailleur for clearance; it does not increase derailleur capacity. Confirm your rear derailleur’s rated capacity before expanding range. It is optimized for 10- and 11-speed 11–36T and 11–40T cassettes and for Shimano road geometry; it also works very well with 9-speed road derailleurs. Not supported: 11–42, triple chainrings, or direct-mount frames. Doubles are only supported with GS (medium-cage) rear derailleurs and must remain within capacity. Specs: 6061 aluminum, 17 g. Stainless steel bolt included; torque 8–10 Nm. Color: Black. Made in USA.
