Markings on the bar and the clamp make it easy to re-position in exactly the right place when adjusting, or dismantling and re-assembling at a later date. They are both functional and beautiful in execution. The clamps are chamfered on the tops so the markings are visible when mounted up against the top yoke (triple clamp).
Angle of the bars is much the same as a standard sport bike, and many modern bikes are packaged so tightly there tends to be only one place where everything 'fits' so don't expect a great deal of adjustability in riding position on a sport bike. Great as a replacement of damaged standard bars. On my bike they provided the additional space I needed on the tubes to allow the mounting of modern radial master cylinders.
Easy to use. Measurements printed on the product so very easy to line up and synchronise on both sides. When you crash, it enables you to quickly change the tube, cheaply, instead of buying a whole new clip-on and avoids you having to take everything apart to get to it.
