Having recently returned from a 5 day trail/gravel bit of everything ride our tandem developed a decent creak coming from the front end somewhere. On returning I thoroughly washed and lubed the bike(it was mud encrusted) the creak started on the first ride after that, I suspect my pedals but am aware of all the other likely culprits. I thought I would take the opportunity to strip out the ebb and clean all the interfaces, its a wedge type with a single cap screw that tightens the wedge the frame is alloy, is grease all that is required inside the shell and on all the mating surfaces or is there another product thats recommended also the wedge cap screw has no listed to torque setting I have always just nipped it reasonably tight and it hasnt moved but wonder if anyone has a number. Ive added a couple of pictures purely to inspire anyone coming to the shaky isles to ride the alps2ocean trail a superb experience..
