Black tightening knob for use on all Spencer Cycle bottle brackets. The knob has a brass insert molded into the knob unlike others ont he market that have only threads in the plastic that strip out when tightend.
If you are looking for a easy to tighten and loosen method for your nitrous bottle bracket then this is for you. The knob is 1.5 inches across for easy grip and has 1/4x20 threads. It comes with a lock washer that we highly recommend being used with the knob. If you are looking to convert your bracket from a bolt style to this we have those kits as well.
NOTE: Bottle Bracket not included. This is just the knob shown installed on a bottle bracket.
