Caught with a pair of skates with oldschool (6mm) spacers not knowing what to do?
Do what I have done for the last 10 years, grab yourself a Roces skate tool
Works for almost anything I’ve tried to do with skates over all those years
Especially with a simple hex tool next to it
It contains a 4mm hexagon on one end, fitting most basic skate hardware, a bearing push/pull side and a third side that only the wizards in some epic tale can tell you about, sorry
