Justin Thursday came with an interesting design, he replaced the middle wheel slot of a Powerslide Trinity frame by a 3d printed h-block he designed. More goodies on Justin Thursday’s Youtube Channel.
Something fun and different. A grind block for 3x110 Powerslide Trinity frames. Jet Set Radio in real life?! - Justin Thursday (Photo).
up: Jet Set Radio Fanart by (?). The design is also close to the skates you can see in Airgear (manga & anime)
