A roller skate having front and rear hangers connected together with main and secondary leaf spring jump bars. Locating and holding pins mount the secondary jump bar to the hangers. A truck carrying a pair of wheels is mounted on each hanger with resilient sleeves and a bolt. Each truck has an upright finger located in a pocket in a hanger. A resilient collar located in the pocket surrounds a part of the finger. The pocket has an undercut tapered side wall which is in engagement with the collar to allow the finger to have vertical and arcuate movement with respect to the upright axis of the finger.
