BUMPS rails are injection molded from ABS — acrylonitrile butadiene styrene — the toughest plastic there is. It is the plastic in LEGO bricks and car bumpers, and there is a reason for that: ABS is built to take impacts that crack cheaper plastics, and to keep taking them — stronger, thicker, and more solid than anything cut from a sheet.
ABSORBS. WEARS. SLICK. SOLID. FOREVER.
The butadiene rubber inside ABS soaks up impact instead of passing it through. Where brittle plastic snaps or spider-cracks on a hard hit, ABS flexes, takes the blow, and comes back.
ABS grinds down smooth and consistent along the bevel — no chunking, no sudden grabs mid-slide. It slides like butter.
The ABS face is naturally slick, so the rail glides on coping, ledges, and concrete with a fast, consistent slide. It does not grab, chatter, or need wax to get moving — the slide is there on the first hit and the hundredth.
The rail stays rigid under your board — no bowing, no wandering, no soft spots. ABS holds its shape under load, so the bevel you start on is the bevel you slide all session.
Heat, cold, sun, and curbs: ABS holds its shape and its toughness through all of it. That is why it is the standard for parts that get abused for a living — and why BUMPS uses it.
Other rails are CNC-cut — machined out of flat plastic sheet and sold as rails. A cut rail is only ever as good as the sheet it came from: the bevel is an afterthought, the edges are machined sharp, and the material has no impact structure, so it chunks, grabs, and cracks where a molded rail flexes and slides. BUMPS are injection molded from ABS — the bevel, the holes, and the toughness are formed in one shot, identical in every rail, built to take the hit and keep sliding. Cut rails are garbage. Molded rails are BUMPS.
