Wolf Tooth Roadlink 10/11s

Description:

The RoadLink™ extends your derailleur hanger to accommodate a wide-range mountain bike cassette on road, gravel, cyclocross, or commuter bikes. It supports simpler 1x setups without sacrificing gear range, or adds lower gearing for steep climbs on 2x bikes. Enjoy shifting across smaller cogs while using cassettes up to 40T.

Specificatons:

• Double chainrings are only supported with GS (medium cage) rear derailleurs. You may need to change the front gearing so the rear derailleurs capacity is not exceeded.
• The RoadLink™ mounts only to standard derailleur hangers.
• The RoadLink™ is optimized for the 10- and 11-speed Shimano road derailleur geometry. It also works very well with 9-speed road derailleurs. Traditional SRAM derailleurs work but not the 1x specific X-HORIZON rear derailleurs. Campy derailleurs work best with cassettes up to 11-36.
• Triple chainrings are not supported (medium cage rear derailleurs cannot accommodate that big of a range).
• Direct Mount-native frames are not supported. 
• Due to the lack of a clutch mechanism on Shimano road derailleurs, secondary chain retention (front derailleur or chain device) may be needed, especially for rough or off-road use.
• Due to variations in derailleur hanger geometry, chainstay length, chainring size, B-screw adjustment, and suspension configuration, individual results will vary.
• This 7.9mm max dimension is controlled by the Shimano spec, but a few derailleur hangers don’t meet the spec. You can file a bit of the bottom "tang" of those derailleur hangers to install the RoadLink™.
