IWIS Chains

I see Blaise has liked my thread from 2015 [ sold on IWIA chains ], where I had fitted my first IWIS chain 1800 miles prior. I still have that chain on the bike, and it is nowhere near worn like the Tsubaki chain was at 5,000 miles. The chain would have been fitted for the 2015 coast to coast [ Kaikoura to Little Wanganui ] in the South Island. Cant remember what the speedo reading was when i put that chain on , but my WOF inspection sheet from 10/10/2016 showed 47251 miles. It is now 66147 miles. so 18896 miles plus the 1800 miles plus what I did between Feb 2015 and 10/10/16 is more than 20,700 miles.
