This new modern universal standard cuts every dimension of a traditional chain in half! 1/4" (6.35 mm) pitch, with sprockets just 3/64" (1.19 mm) thick. In addition to cutting the weight of your chain and chainwheels in half, it also lets you fit twice as many sprockets as the old fashioned systems!
Ha. Had me confused till I saw the monospoke wheel.
