Hi - & thanks for replying and telling about how you do things. I just measured my chain and it is very close to 12-1/16" inch so sounds as if it's got some way to drive. Reassuring - not least because I use the chain in a way similar to yours - smooth shifts & very straight chain lines when selecting the gears.

I don't have any Boeshield T-9 but will see if I can find some onwards - and then just wipe-clean the chain & apply lupe. Possibly with a bit of water if needed. To me it sounds very gentle on the chain ;-)

Cheers,

Jesper
