ok...ive stripped it down and checked everything out. i couldnt see anything wrong with it at all!!! i lubed the bearings etc and put it back togethor with loctite on the thread of the lockring. after this i went out riding for a while. it was fine until i tried a biggish gap. i kicked and nearly got half a pedal stroke with nothing happening.(nearly smashed my face into a wall aswell) after this i checked the lockring, which was tight and then got home and checked all of the bearings were in which they were!!! so i think i have just got a 'bad one' any ideas? cheers Dave
