Yup, this is correct. All modern rims are hook-bead (or crotched).bobj said:In the old days, there were hooked-bead rims (crotched) and straight sided rims. High performance, high pressure tires would blow off the straight sided rims, and required hook-bead style to stay on. I'm not sure, but I think all modern rims are hook-bead (crotched) style.
Hi and welcome! Switzerland! That's on my bucket list of places to visit once the pandemic is over!Hello Guys. i just mounted Marathon plus "for crotched rims only" in a crotched modern Rim and the damn thing blew off while i was putting it back to the Bike. It was super loud and after checking the tube i saw the tire went off due to 6 bars of pressure. When i mounted the tire on the rim it was no difficult at all (i think the tire is too big for the rim , bad production and bad quality control made in vietnam). any thoughts? TIA
