I have gained this mirror for my pedelec, because the original mirror, (B + M, also in the shop), is not suitable for everyday use. The mirror is pleasant small with a good field of vision to the rear, visually it was for me a hit. BUT, it can be on my handlebar, (Concept SL Riser), not use it properly fixed, slowly slips out again and adjusted himself so light that one is only on fiddle, light shocks enough. The Lenkerinnenklemmung is very short and of slight plastic, the principle similar to a dowel. If you try to turn a little tighter, flew me all the mirror mount to the ears, it all up plastic! I think with small handlebar diameters it might work, but the constant self-adjustment is nervous there. My Lenkerinnenmaß is incidentally 20mm.
