I just put a new chain on my bike, my axle block on the sprocket side is reading 4 marks out, and the one on the brake disc side reads 6. If I adjust it so they both read 4 my tire is off to the right, and not stright... Heres what I found out...my axle block on sprocket side has 9 marks total, my axle block on my brake side has 11 marks. So would 6 be correct for the brake side? Since 11-9=2, so difference of 2 marks... Please help guys Thanks.
