The holder corresponds to the figure at Amazon, but that's because even a rubber band it is not mentioned. The rubber band is the "suspenders" and holds the Tala firmly in the bracket. By the way, the head can rotate around the axis in a "grid" that he holds to a handlebar with 90 ° rotated mount the tala in the direction of travel. Am satisfied. Bottle size, I can not determine. I use the holder with a Zweibrüder LED Lenser 8307-T MT7.
