Bloob shrinks the bowl wheel: the Black 80's run 8.0 by 5.7 mm

The numbers Bloob published are tight and specific:

• 8.0 mm diameter by 5.7 mm wide, which Bloob describes as a smaller diameter than most bowl wheels
• Square profile with a larger offset, so the shape stays bowl-wheel rather than rounding off into a street wheel
• About 0.5 mm of overhang past the locknuts
• 70 duro, which Bloob calls "Hard but grippy"
• Abec-9 bearings, so these are bearing wheels, not non-bearing

Black is the only colorway on the listing, and there are no other variants attached to it. Bloob doesn't say how the core is built, what the urethane is poured from, or how many wheels the $35 covers. The packaging note is the one you'd expect on anything with a bearing in it: small parts, choking hazard, ages 10 and up.

Bowl wheels in fingerboarding usually go bigger — more diameter, more urethane, more contact against transition. Bloob went the other way on diameter while keeping the two things that make a bowl wheel read as one: the square shoulder and the offset face.

The geometry is worth sitting with. At 8.0 mm, the axle sits lower relative to the surface than it would on a taller bowl wheel, so the deck rides closer to the ramp or the table. The offset pushes the outer face away from the hanger, and the 0.5 mm overhang means the urethane — not the locknut — is the outermost thing on the axle. Whether that reads as a wider, more planted setup or just a different clearance against coping is a question for whoever has a set on their trucks; Bloob hasn't published anything about how they ride, and neither have we.

70 duro is the part that signals intent. Softer urethane on a transition wheel is the common move; Bloob's own framing is that this one is hard first and grippy second, which puts it closer to a wheel you'd want rolling on a finished ramp surface than one chasing bite on rough plywood. The listing doesn't go further than that phrase.

Against a 32 to 34 mm deck, an 8.0 mm wheel is a small, dense-looking piece of urethane, and in black it reads as hardware rather than as a graphic. That's consistent with the way the product is presented: numbers, duro, bearing spec, nothing else.
