I have a set of custom hubs i had machined out of 6061 Aluminium to replace the standard x2 hubs.
These allow you to have normal x2 turf wheels with your spacers or the new spacers but it also means you can bolt i2 wheels straight onto the hub while only removing the turf wheel and spacer.
It means that you can leave the standard x2 fenders on and have the i2 wheels not rubbing!
Makes it so easy to swap from turf wheels to narrow i2 wheels.
I had a few sets made so selling some off.
$575 USD plus shipping for 2 hubs.
$225 USD plus shipping for the spacers if required.
Message or email me for more pics.
