I originally bought this for the handle bars of my bike but then decided to mount it to the highway bars instead. That was the best place for this on my bike in my opinion. The chrome blends into the bike. It has a thumb screw so it can be easily detached when not needed and it holds large drinks with ease. Looks great too. I love it! I am going to buy another for the saddle bag guard so my wife can have her drink when she rides with me and I can simply turn the thumb screw and remove it when she is not with me.
A very poor design for keeping the holder from rotating. With a full cup in the holder the holder wants to swivel even after the nut is tightened numerous times. I ended up strolling a small hole through the clamp and the shaft going through it and putting a small pin through it so it could not rotate. Save your money - it's not worth the modification required .
