Im chaseing some creaks in my Megatrail. One thing that ive had to mess with is this insert. Mine protrudes through the frame (on the hub side) maybe a 1/16 if an inch. It almost always seems to move out flush. Could be a cause for the creaking. Im thinking it would make the shoulder not seat right and let it wiggle. Is this an issue? Should it be flush? Maybe a some shimzs under the shoulder of the insert? Maybe i need a new bike with coilz.
