well they just arrived.. finally geez
a few things when i said hard rubber core i mean like really hard plasic-ish rubber core
and i need to machine them a bit still
they will not fit a fork right now they are WIDE
but i just bent a fork and threw them on for laughs
and they are so smooth even with internal bearings (which suck) that slide side to side a bit
and the urethane is pretty hard but i haven't really tested the grip yet
i will post pics after machining
