Replaced the rear wheel on my pub bike with one that's actually 135mm OLN, not about 133mm, and brought the butterfly bars 10mm closer by switching to a shorter stem. Hopefully that should sort the strange creak from the back end and also make it a little more comfortable to ride.
Before switching wheels I regreased the hub on the old Dawes tourerwheel I was fitting. It's not in very good nick as one of the cups has a rust patch!
