Wheels Explained: Choosing Fingerboard Wheels
Materials, durometer, sizing, bearings, and shapes — what changes how a wheel feels.

Materials, durometer, sizing, bearings, and shapes — what changes how a wheel feels.
Fingerboard wheels are commonly made from either molded/CNC plastic or poured urethane (the same family of material used in real skateboard wheels). The two materials behave differently, and which one suits a setup depends on the rider's goals rather than one being universally superior.
Durometer describes a wheel's hardness. Fingerboard urethane wheels are usually rated on the D (Shore D) scale. Documented durometers seen across brands and retailer listings include figures in roughly the 60D–72D range, with specific values such as 60D, 61D, 64D, 65D, 68D, 70D, and 72D appearing on product pages. Importantly, durometer alone does not fully determine feel: brands note that two wheels with the same durometer can feel different because of urethane formula, pigment, and shape.
Wheel diameter (height) and width affect both how the setup rolls and whether bearings and wheels clear the deck and trucks. Documented fingerboard wheel diameters span roughly 6mm to about 8.7mm, with common sizes around 7mm–7.5mm. Width figures such as 4.4mm and 5mm appear on product listings.
Most pro fingerboard wheels use small ball bearings pressed into the wheel, which is what gives a smooth, free-rolling spin versus a solid plastic wheel. Listings commonly cite an ABEC rating (e.g., ABEC-7 or ABEC-9). Bearings come in single-bearing and dual-bearing configurations, and this affects truck compatibility.
The shape of a wheel's contact face changes how it grips and slides. Brands use a range of named profiles. The terms below are documented across brand and retailer pages, though naming is not standardized across the whole market.
Several wheel brands publish specs on official or retailer pages. The notes below reflect documented facts; buyers should verify current models directly, as lineups change and limited runs come and go.
Used wheels can be a good value, but specific wear modes affect roll quality and bearing fit. These checks are documented across buying guides.
A complete wheel listing lets a buyer evaluate fit and condition without guessing. Combine confirmed specs with honest condition notes.

Kingpin wheel listings most often go wrong by omitting material, durometer source, bearing type (single vs. dual), diameter, and condition (flat spots, bearing slip, yellowing). This article gives buyers a concrete checklist of questions and gives sellers a template for complete, source-backed wheel descriptions that reduce post-sale disputes.
