George Jetson had it made. Three hour workdays, talking computers, spaceship cars, and the lone money earning task of pushing a button every day makes the oh so far off future too good to be true. The only thing that seemingly ever got Mr. J down was Mr. Spacely. Spacely Sprockets and Cogswell Cogs fought tooth and nail to outdo the other in cranking out new gears. Here at Wald, we like to think we'd give them both a run for their money. Wald sprockets are available in 36 tooth 536, 40 tooth 540, 42 tooth 542, and 44 tooth you guessed it, the 544 sizes. Perfect for kid cruisers and BMX bikes with a historical appreciation for steel's contribution to bicycling. All models are chrome plated and offer inch pitch x 18 inch.
