From Mobutusan at eSk8.builders DIY Forum:
Finally getting around to install these on my Spud. Gonna try to carve them into submission. (Not gonna happen!)
They are harder than they look, like a petrified gummy bear, and they feel very solid. And the translucent color is really cool. I think @b264 suggested the idea of LED’s in the riser, but I ain’t got time for that, so a shredlight mounted in front of it will have to do for now.
