The late Fred DeLong took a series of high-speed photographs back in the 1960s that showed how on a 1xN drivetrain a
rear shift can, under the right (wrong?) circumstances, snap a wave in the chain that will hop it right off the front ring.
Nothing-New-Here Department: In
The Dancing Chain there's an illustration of a 1X4 fitted with a little keeper over the chainwheel. The illustration is dated 1931.
Alex Moulton is a fan of one-by drivetrains, and over the last 45 years has turned out models with factory 1x6, 1x7, 1x8, 1x9 and 1x10 set-ups.
