The bar ends are easy to assemble and are secure total. Installation with a normal Allen I do not recommend because you can not spend enough force with the short key. I have the handles fitted with a ratchet and the associated Inbusschlüsselaufsatz and could thus pull the screws extremely strong due to the better leverage. The inner diameter of my link is 19.1 mm, that is even larger than suitable for the handles. However, due to the mounting described above, the handles are secure and super not slip. I could also often test the terrain. Super Bar ends, I would buy again at any time and the price is also unbeatable.
