Twisted birdcage muffler, chrome (pair)
Decorate your 20" lowrider bicycle rear wheel. Bolts onto the axle of a coaster wheel, one muffler on each side of the wheel. Use an extra coaster wheel axle nut to bolt the mufflers on. If you do not have a lot of room left on your coaster wheel axle you can order a pair of our extra thin 4mm axle nuts, part 517051.
