Speed Sensor Magnet Assembly 6 Bolts Dyname 4

I got a new wheelset. The original hub had the splined interface. My new, way-cooler rear hub takes a 6-bolt disc rotor. This makes it work. Alternative was to glue magnets onto the rotor itself - that actually works fine, too. But with this doo-dad, it's legit.

Product function is 5 star, gave it 3 stars because IMO it should have been included with purchase. My bike came with a Sram UDH adapter but Shimano drivetrain. By the logic that some bits are included in anticipation the end user will make some upgrades the 6 bolt sensor would have been nice to have been included.
