• In need of an expander plug that will fit a 22mm inside diameter carbon steerer tube of a 1" Mizuno fork. Also really daunting task to find a 1 1/8" spacer with a small (+-32mm) outside diameter.

    Anybody have any tips?

    I've used these on a look hsc fork and on a thick steerer ID'd alpina wing fork.

    Buy some from me. I have spacer packs containing a set 1mm+2mm+4mm+8mm with an OD of 31.8mm.

  • Also had a long search for 1" carbon steerer expander bungs (mine has ID of 20.5mm). cnc-bike offers one to fit forks with ID of 20.5 to 25mm for 8 Euro, hopefully it will fit my fork without imprecise sanding.

    EDIT: If I don't manage to fit it right, I will get someone from technical university to machine me an insert alla @mdcc_tester

    Are you sure it's that big? That would be pretty thin walled for a carbon steerer. I've got a couple of 1" expanders in my parts bin, but as they are designed for typical aluminium or carbon steerers, neither looks likely to stretch to 22mm
