thanks guys,
i checked if it had lost its torque, but the "head" was still tight...
the crank is a dpr, so good qualitiy....
i might be getting paranoid
i will get teh KEP off today and put my full weight on it again...
i guess it will be ok if the head doesnt fall off
Good. Usually with a press fit on you will get a "PING" - "CHING" or "BONK" sound
when flywheel is where it should be. To make the job easier you can take a hammer and knock on the 38mm pipe, then try the wrench, knock again, wrench.. you get my point.
