Thanks for all the support.
The new crankset arrived from Germany yesterday all g with a third BB (which matched the original so was instantly fitted).
All seems.well although only 15 miles covered. Usually the clicking occurs after a mile or so...fingers crossed.
Wow London is so quiet without my one man band.
Also, very impressed with the German exporter. Swift, as described and all totally genuine parts.the set, along with BB and.all bolts etc, £60 inc dispatch. Some shops in the UK wanted over £100.
