Fidlock delivered a solution to a problem that I didn't realize existed. I often rode without water bottles based on the simple fact that I never used them often because their positioning is inconvenient. I find myself asking "which way to I remove this" based on which bike I am on, and find myself "cramming" them into the cages if I am done taking a drink while riding. For shorter trips, like around town to the gym or for shopping errands, having water bottles with is unnecessary for me. This solution gives a very clean look to the bike in the instances where I do not need a water bottle, and offers a very convenient way to remove and reattach bottles when I do. I have adopted this system for four bikes I use on the road. It's just perfect.
All of the reviews and personal stories I have heard about Fidlock have been true. This is worth the investment if you want water bottle accessibility perfection and place value on having a clean-looking bike.
