Hollow Low Profile

ST1 Hollow Low Profile trucks bring the ride height down for a more stable, locked-in feel - hollow-kingpin weight savings with a lower center of gravity for technical street skating.

Low Profile drops the ride height for a lower center of gravity and quicker flick - the setup skaters switch to when boards start feeling tall. Reviewers keep documenting the switch from legacy lows on the blog; the size chart covers the rest.

Every truck on this wall shares the ST1 DNA: engineered grind clearance, a turn that stays predictable at speed, and parts that interchange across the entire line - so a setup built today can be rebuilt for years instead of replaced. That is the skater-owned math Mike Sinclair started the company on.

Buying for a specific deck? Match the axle width to the deck width and the wheels sit where they should - the size chart maps every Slappy width to the decks it fits. Orders ship tracked from the Sidewalk Distribution warehouse, or your local shop can order any of it in.

New to the brand? Start with the story: skaters kept telling Mike Sinclair what was wrong with trucks, and instead of agreeing over a beer he built the fix. The blog keeps the receipts - reviews, comparisons against the legacy brands, and riders who switched and stayed. The trucks themselves do the closing argument.
