I know there are a couple of different company's that did the twin top tube bars
the tube ends seem different - mine have a small rounding to them and a flat top to them - mine doesn't have any knarling to the stem grip point ? - you can see where the bends are in the bars that the tubing has slightly been flattened and you can feel this ?
28" wide
14.2/8" end cap to end cap on top tubes
6.1/2" from top tube to stem grip point (mesured from top/outer point)

2.1/2" inside gap between top twin tubes
1.2kgs in weight
