What a difference! Chain tool, never used one before, bit of YouTube just to see how the tool works and I think it's there. Took about an hour with a bit of faffing and checking and rechecking but looks like it's done. Time will tell on the first ride...
Only 4K miles, barely a winter ride and lubed every few hundred. Not that you would think so!! @MaDProFF happy to report the 110 link chain has reset ride height and if anything it's lowered a bit as it seems to be a little flatter plane
