The PBA-22 derailleur hanger extension is a unique device that offsets the position of your road derailleur to make it possible to run a wide-range mountain bike style 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. 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 as large as a 40T cassette.
●LightWeight , Precision made alloy Hanger
●Easily installed in less than 5 minutes by any home mechanic.
●The PBA-22 mounts only to standard derailleur hangers.
●PBA-22 repositions your derailleur to provide clearance for larger cassette cogs but it does not increase derailleur capacity. It is critical to find and understand your derailleur's capacity before attempting to expand its gear range.
●The PBA-22 is optimized for use with 10 or 11-speed 11-36t and 11-40t cassettes . The PBA-22 is optimized around Shimano road derailleurs. It works great for road, cyclocross, touring, commuting, and drop-bar mountain bikes.
The PRA-22 is optimized for the 10- and 11-speed Shimano road derailleur geometry. It also works very well with 9-speed road groups, all SRAM groups, and Campy derailleurs! One note is that with Campy it works best with cassettes up to 11-36.
