What can I do about a Shimano BB (BBR60 - Italian threaded) in which the crank is not spinning freely? Even without the chain on it feels like it takes too much effort to turn the cranks. Weird thing is, even though I built this bike up a couple of years ago when the BB was brand new, it's hardly done any distance. I'd guess in the few hundreds of km. It doesn't feel grindy or gritty or anything, still quite smooth if that makes sense, but just hard to turn the cranks. Does it likely just need servicing/new grease? (Shamefully I've got no experience of servicing a BB, maybe that's about to change!)
