We found another one of these Rump Rider Rotor Return springs in a box in our storeroom. This is an incredibly rare old school BMX part/accessory. This is NOS, in the original packaging and has never been opened or installed.
As you may be able to tell from the pictures, this installed onto your stem / \"gooseneck\" on top of your ACS Rotor (probably worked with knockoffs, too, but if you\'re looking at this you likely have the real thing) to smoothly return the rotor back down to the neutral position.
Made in the good ol\' USA by Rump Rider, Inc., which is probably not worth Googling, as \"Rump Rider\" is going to return a whole bunch of results that have nothing to do with this.
See photos; ask questions.
Will ship on the first non-Monday weekday following payment.
