Ordered a set of these from 3rd party seller on amazon to fill out order. Came today in a grey plastic bag. Really wanted the 5 1/4" height to sit straighter in saddle. They measure only 4 1/2" c/l of dia that stem clamps to c/l of tube going to grips. Also they are black painted not chrome which is as described, but there is very faint to no knurling where stem clamps on. Any way to verify if it is really a wald part or an asian knock off? In product reviews someone noted they could not clamp the bars firmly and they slipped!
