cheers guys,
the rear mech hanger is always the first place I look when I get strange sounds and its always kept topped up with grease and loctite
refitted the pivot bearings with loctite .
checked and re greased loads of bolts .
I even took the pedals off and popped some fresh grease on…still the same
getting stressed
chainset off and refit and and at the same time took the chainring bolts out and put some fresh Loctite on….Bingo !!
So looks like it was the chainring bolts…a new one for me
and while all that was going on I stripped and fitted new bearing to the rear hope hub
bike feels like new again …even the seat stopped creaking
Ladybower in the morning it is then !
thanks again guys
Andy
