The BBR Tuning Adapter is a durable aluminum unit that provides fast and easy installation when used with the BBR Tuning Sprocket. Unlike the traditional sprocket clamp assembly, the BBR Tuning Sprocket and Adapter Assembly ensure concentricity with the wheel hub by using the unique two-piece adapter that wraps around the rear wheel hub and enables you to drive the entire wheel instead of applying pressure on the spokes. ADAPTER ONLY, DOES NOT INCLUDE THE SPROCKET.
sweet! well made!
Must Have These hub adapters are mandatory if you want a dependable motor bike. Very easy to mount and everything is perfect. Yes, you must use threadlock (blue) to keep things locked down. The 7/32” Allen key size is strange but no big deal. Lock this thing down and you are good to go. Worth every penny!
Only way to go Nice machining.....the only way to go if you want to feel comfortable about not dorking up your spokes over time.
Best Part The best part is that this is the best way to do a motorized bike. However, the worst part is that they are 100% BS when they say 2 to 7 day shipping.Order from bikeberry and maybe you get the part maybe you dont. Best if you go to warehouse and will call yourself. Otherwise goodluck getting shvitch from this dump truck of a company. Read reviews on pissedoffconsumer.com
Mandatory, beautiful, but... I put 4 stars to attract attention to the need to place a compound like Thread Lock on the hub surface, as well as the 3 screws. It is probably mentioned somewhere, but this design has an absolute stop point (which it must to work through the spokes and preserve concentricity), and is milled precisely, but China-made hubs may vary in dimension, so the assembly could appear tight, but prematurely loosed and break spokes as mine did. Mated with the beautiful sprocket, this was the first step in my bike's transformation from 'cute' to professional and beautiful. I also have other billet parts from BikeBerry that complement the overall function and appearance.
