This is a brand new Townie 3 speed wheel. Be sure to measure the inside diameter of your drop outs. This hub is wider than a 1 speed coaster brake.. This hub is 5 1/2" wide so your dropouts will need to be wider. townie wheel is 559x19 ERTO .. Will need a Tire 26x1.5 to 26"x2.0.. Townie tires are 26x2.0. . I f you have a single speed Townie it is useless. You CANNOT stand up to pedal. with THIS 3 SPEED AND YOU WILL NEVER NEED TO STAND UP TO PEDAL. JUST SHIFT TO #1 ,PULL BACK ON THE HANDLEBARS AND SCOOT UP THE HILL. PROBLEM SOLVED. If you need a matching used front wheel add $20 additional. Both wheels are double wall.
