Yeah you can just switch the collar, the problem is that the lever 07 type are not avaliable. Ash said they 'may' be available in septemeber but would prefer one sooner.Isn't it just the clamping section that's different?
so in theory, if you could find that section, you could just swap it out for the old screw style?
where did you source one in the end? I'm looking around for one too when they are released.
