An automotive door hinge assembly is provided with a hold-open device with a leaf spring member carried on a first part of a hinge assembly, and a compound roller carried on a second part of the hinge assembly, wherein the compound roller engages the leaf spring member with the combination of a flexible and resilient first material portion and a hard, rigid second material portion of the roller assembly during its motion between the door open and door closed positions. Preferably, the hard, rigid second material portion of the roller assembly is made of a single piece spool having a first, reduced diameter, annular shoulder interposed between two, longitudinally spaced, enlarged diameter, annular shoulders. To reduce noise, a synthetic bushing is preferably disposed between the spool and a roller pin of the hinge mechanism and the first annular shoulder has a roughened surface engageable with the first material portion.
