Just as happy to buy a new Dimension or Velo Orange at the proper size if needed. Was just wondering if the bars ran small or the stems ran large in some way that they actually fit. Seemed from the video that they took care in picking the parts so I thought perhaps this was the case.

Not in love with Thomson's particularly at full price for a used or NOS item. I've cracked the faceplate on them with proper sized bars (my bad no torque wrench but only using a Park Y wrench). The full price ebay ones aren't available in the size I'd need anyway (a silver 26 90mm 5 degree if anyone is looking to get rid of or trade for a black 80mm 0 degree 31.8 X4 brand new)
