Eliminates chain interference on right side installations. Provides extra ease of sharing the Bike Tow Leash between bikes, and rapid adjusting for different dog heights. Use requires minimum of 1 & 1/2 inch flat area surrounding the rear axle.
For solid axles 3/8 or 9mm diameter, with hex nuts on both sides, you need 1/4 inch [6mm] available axle length. So installed you will have 5 full turns of thread engagement on the nut. For bikes with quick release lever and 5mm dia. skewers as shown, extra axle length is not necessary.
Comes with a 5mm recessed axle nut, 5 & 6mm bolts to engage slot and threaded hole in frame for extra security. Instructions included.
