SJS Customer Service:
Hi,
We don't have any shims that are the correct size straight away for your needs I'm afraid. You could modify this shim by increasing the inner diameter to 33.9mm or you could use a "drinks can" shim as the alloy in these is usually around 0.5mm thick which would give a 1mm increase in diameter around the post.
Thanks.
