The Apexmfg standard adjustable clip-on comes in 50mm - 53mm, smaller sizes require ordering a reducer collar set.
These have a unique 2 piece clamp so no top triple removal is needed for installation of our clamps.
The bar has 5 possible angles, 9*, 4.5*, 0*. -4.5*, -9*.
These angles are easily set using the internal locating pin for a perfect setting every time
