I have a 12x and I just measured my rear wheel width and this is 166 mm. So I have to make it 6 mm wider. How do I do that? Where do I have to put the spacers? Where can I get the spacers from? Is Corally selling these spacers?
Oze- Calandra carries 7mm spacers, CRC # 4737. I ended up using about 18 shims (20 in a package), with 12 on one side and 6 on the other to center the wheels.
