Slappy x Bam ST1 Hollow Trucks | 8.5"
Bam's got trucks now — and they slap.
The Slappy x Bam ST1 Hollow is a full collaboration between Mike Sinclair's Slappy Trucks and Bam Margera, finished in a standout black hanger and purple baseplate colourway. Under the hood it's the same dialled ST1 Hollow geometry that's earned Slappy a loyal following — hollow axle and kingpin for reduced weight without sacrificing feel, maximum grind clearance so the kingpin stays out of the way, and that fast, responsive turn Slappy is known for. Sold as a pair, ready to bolt on.
Key Features
✅ Hollow axle and kingpin — lightweight without losing strength or feel
✅ 53.9mm height — balanced platform for consistent pop and smooth turning

✅ Black hanger / purple baseplate colourway — a Bam x Slappy exclusive finish

About Slappy Trucks
Slappy Trucks was founded by pro skater Mike Sinclair, who spent years in lockdown obsessing over every detail — bushing height, hanger geometry, grind clearance, kingpin depth — to build what he considers the ideal skateboard truck. The result is a truck that turns fast, grinds clean, and needs no break-in time. The Bam collaboration brings Bam Margera's signature colour scheme to the ST1 Hollow platform for a setup that's as distinctive as it is functional.
