M30 Handlebar and Riser Combo KitM30 Handlebars Rox T Style Stem Pivoting risers Rox Thin Snow Grips. This kit is a perfect upgrade from the stock setup. It works on many sleds with T Post style stems. The M 30 design started as the same profile as our M 28 handlebar however we extended the overall width to 30. 5. By doing this we were able to maintain our tight center bends and increase our grip area for the wider applications. This is the perfect handlebar for the mountains,
