Shown here is the complete weld-on SUB MOUNT kit. SUB mount stands for "Stabilizer Under Bars" and nicely tucks the unit in under the bars. This is a weld on kit which requires a simple 1/2" weld to the backbone as the headtube is too small for a bolt on ring. The sub mount kits raise the bars approximately 26mm. Lower bend bars are available if the added height is not desired. The kit includes everything you need and step by step pictured instructions, along with an Owner's manual. Comes with 3 fully adjustable circuits and a true high speed valve for those big surprises. A very nice compliment for this bikes handling and a sure benefit for a tired rider.
