Dirty Fingerboards' Ill Pills Street: 7.7 by 4.7 mm, 70D, ABEC 9

Here's what the listing commits to, in full:

• Diameter: 7.7 mm
• Width: 4.7 mm
• Urethane: what the shop calls a "perfect 70 D urethane formula"
• Bearings: ABEC 9
• Made in: the Philippines

That's the whole spec sheet. The listing doesn't say how the core is built, doesn't give a weight, and doesn't break the durometer down any further than the 70 D figure it prints.

The comparison photo shows big street, regular street and mini side by side, and the shape names do most of the explaining — but the 7.7 by 4.7 mm figures on this page describe the regular street shape, the one being sold here. Dirty Fingerboards hasn't published diameter or width for the big street or the mini anywhere in this listing, so treat the photo as a proportion guide rather than a measurement you can plan a build around.

If you're the kind of rider who keeps a spare set of each profile in a tin, that photo is still the fastest way to decide which silhouette you're after before you get into numbers.

Diameter and width are the two dimensions that change how a set feels under your fingers, and they pull in different directions.

Diameter (7.7 mm). A taller wheel raises the deck off the surface, which buys you a little more clearance over a ledge edge or a coping lip, and it carries speed differently across a table or a park surface than a smaller wheel does. It also means more urethane between the axle and the ground when you come out of a transition.

Width (4.7 mm). Width is contact patch. A wider wheel plants more urethane on the surface, which shows up in how stable the board feels rolling into an obstacle and how it behaves landing back down. Against a deck in the usual 32–34 mm range, it's also a visual decision — some riders want the wheel tucked under the deck, some want it sitting proud.

Bearings. ABEC 9 is a bearing wheel, so you're choosing roll and the sound that comes with it over the quieter, more locked-in feel of a non-bearing set. That's a taste call, not an upgrade in every direction — plenty of riders on park setups prefer no bearings full stop.

The 70 D figure is the one number here without much context around it. The listing calls it a "perfect 70 D urethane formula" and leaves it there.

The Ill Pills Street are listed at ASI Berlin, the shop Timo "TKY" Kranz founded in 2003 and which has run independently as the ASI Berlin Shop since 2017. Stock and shipping are the shop's to confirm, and the brand hasn't announced anything about a wider release beyond this listing at the time of writing.

If you're in Berlin, ASI runs an open fingerboard workshop at the shop on Wednesdays from 4 to 6pm, per its own site — the fastest way to put a set on somebody's board and see the difference before you commit.
