I should make it clear that the SB roller clutch would have been a lot easier to use than the original ATCO one - you can operate the SB one with your left thumb while keeping both hands on the handlebars. The ATCO had two clutch handles like the SB blade clutch. My admiration of the 2-clutch ATCOs is aesthetic, not functional. Besides, I used to admire one when I was 6-7 years old. I got myself imprinted with an attitude.
