It's for street skaters on 7.875\" to 8.125\" decks who grind everything: kerbs, ledges, hubbas and slappies.\u003c\/p\u003e\n\n\u003cp\u003eOn a standard truck the kingpin nut sticks up above the hanger, and that's what snags mid-grind. Here the ultra low hollow kingpin is inverted, threading into the baseplate so nothing pokes up. Slappy rates it at 12.5mm of grind clearance and a 25° slappy angle, double the clearance of the ST1 Classic. A hollow axle brings it down to 337g per truck, and it turns quickly with no break-in time.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltra low inverted hollow kingpin:\u003c\/strong\u003e nothing sticks up to catch on grinds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12.5mm grind clearance:\u003c\/strong\u003e the most in the ST1 range\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e25° slappy angle:\u003c\/strong\u003e lock into kerbs and ledges further\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHollow axle:\u003c\/strong\u003e 337g per truck, Slappy's lightest truck\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForged baseplate:\u003c\/strong\u003e with a shorter top bushing, per Slappy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuick turn, no break-in:\u003c\/strong\u003e dialled straight out of the box\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e8.0\" axle:\u003c\/strong\u003e made for 7.875\" to 8.125\" decks\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold as a pair:\u003c\/strong\u003e two trucks, enough for one board\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecs\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 8.0\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAxle width:\u003c\/strong\u003e 8.0\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHanger width:\u003c\/strong\u003e 136mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 53.9mm (Slappy standard height)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits boards:\u003c\/strong\u003e 7.875\"–8.125\" (7.75\"–8.25\" works)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 337g per truck\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKingpin:\u003c\/strong\u003e Ultra low inverted, hollow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAxle:\u003c\/strong\u003e Hollow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrind clearance:\u003c\/strong\u003e 12.5mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSlappy angle:\u003c\/strong\u003e 25°\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Polished\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold as:\u003c\/strong\u003e Pair (2 trucks)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat Size Board Does It Fit?\u003c\/h3\u003e\n\u003cp\u003eSlappy names every ST1 by the deck width it fits, so an 8.5 truck goes on an 8.5\" deck.

When the world locked down during the pandemic, Sinclair started pulling his trucks apart in his garage. In his words, it was either trucks or learn Japanese. Sampling ran for more than two years before he announced Slappy in late 2022, independent and run out of his garage.\u003c\/p\u003e\n\u003cp\u003eEvery ST1 is built around one idea: the best grind clearance possible without giving up a good turn. Slappy publishes its own grind clearance and slappy angle figures, and its inverted kingpin models push them furthest. Slappy also sells its parts one at a time, so a worn piece can be replaced without buying a whole new truck. Skaters pick Slappy for kerbs, ledges and slappies that lock in without the kingpin catching.\u003c\/p\u003e\n\n\u003ch3\u003eFAQs\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat size board do the Slappy ST1 Inverted Hollow Light Ultra Low 8.0\" trucks fit?\u003c\/strong\u003e\u003cbr\u003e\nThey fit decks from 7.875\" to 8.125\", with the best match on an 8.0\" deck, and still work from 7.75\" to 8.25\". Slappy names its trucks by deck width. On an 8.25\" to 8.5\" deck, step up to the 8.25\" size.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is an inverted kingpin and why does it matter?\u003c\/strong\u003e\u003cbr\u003e\nOn a standard truck the kingpin nut and thread stick up above the hanger, which is what catches on kerbs and ledges. An inverted kingpin threads into the baseplate, so nothing protrudes. You get more clearance, fewer hang-ups and smoother grinds, especially on slappies, feebles and smiths.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between this and the ST1 Classic?\u003c\/strong\u003e\u003cbr\u003e\nGrind clearance and weight. The Ultra Low has 12.5mm of clearance and a 25° slappy angle against 6.3mm and 15° on the Classic, and weighs 337g per truck at 8.0\" against 374g.

Slappy lists 53.9mm for its standard-height trucks, which suits typical street wheels in the low to mid 50s without risers. If you run 56mm or bigger, or soft cruiser wheels, add a 1\/8\" riser and use 1\/4\" longer bolts.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo Slappy trucks need breaking in?\u003c\/strong\u003e\u003cbr\u003e\nNo. They're responsive straight out of the box.
