In the picture above: Look at the largest "cut out" towards the center of the control you will see how the control mounts to the handlebar & how the wires & hoses are all routed directly into the ID (inner diameter) of the bar stock. This method allows for a simple "plumb job" of the controls onto the handlebars. The "clear tubing" you see is a visual representation of what would normally be the handlebar. No neck-downs, no dimples - easy & clean! It also shows the master cylinder piston & spring and the dual-cable internal throttle just to the right.

The picture above shows the entire control cut away. Its shows you that the cylinder under the grip is actually your fluid reservoir. Plenty of fluid in ours! This picture is also a good representation of our "integrated control" that mounts to the end of the bar, the control will actually make up 7" of length, this would be the "neck down" of a standard 1.25" handlebar. We maximize the space to give you a complete product out of the box. Our Climax Controls work as good as they look!
