Does anyone know if you can get supermax sprockets exchange in the UK or do you need to send to the US?
I had mine done about 3 years ago and had to send it to the US, turn around was about 3 weeks they do pulleys in batches so it just depends where you fall in the production cycle as to the actual timescale. Cost if I remember correctly was £450, shipping £60 return and import duty £90.
