Cheers guys, stripped the drive train down completely. Re-fitted the CK BB, stripped the pedals down again and packed them with grease. Removed cranks, cleaned and greased – removed pinch bolts, cleaned and loaded with copper grease. I removed the chainring bolts and spacers and replaced with some narrow sockets that I had.
Rode it over to the nearest hill. The creaking has improved but there is still some noise. I have some stronglight bolts on order from Ebay, and will also invest in some blue instant gasket, as yes, the surge does have removable, and sliding dropouts.
After that, I’m done and will just have to throw the f*****g thing in the bin.
