Surely not 10mm? I work out that 55% of 180 is 99mm and 50% of 190 is 95mm. Meaning the 180 is 4 mm more in radius. I have ordered a chain with a couple of extra links which will move wheel back by the distance of 1 link which will be enough. Almost got carried away and got renthal carrier and rear sprocket up 3 teeth with an even longer chain (+4 links). Bought a 14 tooth sprocket as well but may fit that to the Multi. I broke a Breaker bar the other day trying to undo rear sprocket nut and took it back to Halfords today. I tried to claim I had bought it recently but lost the receipt. Shop guy raised an eyebrow as he informed me they had not sold that model bar for a few years! I actually bought it about 5 years ago. He didnt have any in stock but told me to call in on Friday and he would have one waiting for me FOC. Excellent.
