As above. I have two sets of wheels for my Inbred; road set with slicks & an off road set.
There is a small discrepancy in the hub width so I keep having to re-align the calipers when swapping between wheels. Would be far easier to shim the narrower hub…
Syntace appear to do them, but I can’t find anyone selling them in the UK.
This came up in a thread a while ago & I found some Fibrax shims from Billy’s that I suggested. I ordered some myself, but they have turned out to just be .2mm washers which work, but aren’t great. They sell them in packs of 10 too which is a bit silly for a 6 bolt rotor.
If it comes to it, I’ll just order some from abroad, but I’d prefer not to have to…
