I've been around cycling since 1971 and have very fond memories of hookless rims. What a treat they were to deal with when mated to the wrong tire. Then I discovered hooked rims around 1978 and was disappointed that just about any tire made in the appropriate diameter was able to be installed with ease and that they stayed put on the rim, even at high pressures!
WTF is wrong with the bike industry and better yet, what is wrong with the consumers who insist on following the pull on their ring noses?
