I tried them today for the first time, What a change from the old Mustad easi glue. Glue technology has come on in leaps and bounds. So now keep fingers crossed, see if they stay on and how long they last. All our roads have been top dressed with a savage coarse grit. The glue is a revelation from the old Loctite 406 or whatever it was. We went for a ride after fitting them. but due to the coarse top dressing on the roads we already wore down to the racing plate. we'll see if they are any good or not!
