The weld on kit is relatively easy to install and requires 2 small welds, one on each side of the frame bracket. This kit is specific to each bike with consideration for which combination of bars and triple clamps are being used. The frame bracket is a universal, weldable tower, that can be adjusted to accomodate different height applications and frame shapes. Because the weld-on tower doesn't have to mount around the head tube, it is very narrow and compact, lending itself quite nicely to applications where space between the gas tank and head tube is narrow. Weld-on towers are normally a stronger option depending on the design of the stock head tube. Each kit includes the handlebar bracket, weld-on tower, instruction manual and applicable hardware. (NOT for Aluminum Frames).
