Oversized version of the BSD Stacked stem. The Stacked OS stem has been machined internally to save weight and features BSD\'s gorilla grip system which has a larger 25.4mm clamping diameter to work with Oversized handlebars. The stem clamping area diameter is increased from 7/8\" (22.2mm) to 1\" (25.4mm). This increase in diameter gives 14% more clamping area than on regular 7/8\" handlebars, so when you\'re nose diving down a 12 set your bars are less likely to slip. .embed-container { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%; } .embed-container iframe, .embed-container object, .embed-container embed { position: absolute; top: 0; left: 0; width: 100%; height: 100%; } ###section### Product Specs TYPE: Top Load REACH: 50mm RISE: 33mm CLAMPING DIAMETER: 25.4mm WEIGHT: 312g
