My second pair of these excellent, tough aluminum alloy hand grips. They are well made and feel heavy duty. They are longer than most grips, 120mm grip area with an overall length of 147mm. When the bolt is tightened, they hold as if they were welded in place. They come with black plastic end caps but any 22.2mm cap fits. I have one pair as inboard grips on a 20mm flat bar and the new pair is holding bar-end brake handles on a 5mm flat bar. The knurled part holds onto slip-on handles tightly.
