The BBR Tuning Sprocket is a durable aluminum unit that provides fast and easy installation when used with the BBR Tuning Adapter. 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. SPROCKET ONLY, DOES NOT INCLUDE THE ADAPTER.
The sprocket and split mount come as a set of well machineed aluminum alloy.Unfortunally the mount is too large for my hub and will have to be shimmed with belt leather.I am holding it in reserve while using a steel sprocket with two
Rubber tire core donuts for breaking in my chain .A real pain with nine bolts to line up!But much cheaper and better wearing.Measure your hub carefully with a vernier caliper and call before ordering,I wish I did.
Bought the bbr mags after buying 48t sprocket and adapter.48t looks much thicker don't think it's interchangable.im old, I need torque for hills.wantung the 48 instead of the mag stock 36t.dammit!
Lightweight high quality sprocket available in several numbers. Choice concerning grearing is what different motorized bicycle builds want.
The sprocket is attached to the wheel ingeniously. With quality hardware.
The BBR Tuning sprocket uses advanced skills, grand on experienced bicycle builds.
Everyone uses different methods. I'm happy with leather pressed tight against the hub.
What a difference!! This should be the first upgrade to any bike engine kit. I received parts a few days after I ordered it. I will be ordering from seller again.
The sprockets are great, so long as you can get them onto an ill-fitting hub adapter!
