Review on Ibera Bike Handlebar Cup Holder: Black, Multi-Way Mount for Commuters and Road Bikers by David Dortch

First of all the cup holder is great for what I intended to use it for. However, the bracket is not suitable for 31.8mm handlebars. This is the standard dimension for folding brackets. It fits on my mountain bike, but not on the handlebars of my touring or road bike. Doesn't match the handle either. It fits on a touring bike's steel frame, but I didn't intend to mount it. I am giving this product a bad rating because it is advertised as fitting most handlebar sizes. But it won't fit a standard sized stem or drop bar. Overall I think the description of this item is misleading. I would not purchase this item if it was clear that it would not fit a 31.8mm handlebar. Update: It's broken. Ibera products do not meet the standards.
