I tired posting this to the support form but I could not get it to be sent...
I've been using varyings sizes of SPFs for some time (56 - 62, today two sets of Grind for life). I love them! I also use you steel labyrinth bearings and your ceramic bearings, they are better than Rockin Rons ceramics imo.
Anyway, for my streetboard I bought the 56 Softcore. I like them but the outer core got loose on one wheel and come off when I turn hard. I tried gluing it back (contact glue), but it did not work, still comes off.
Any idea what to do? Ho do i fixate the perimiter to the core?
