Review on 🚲 Srami 2 Pack Bike Water Bottle Holder with Repair Tool Kit - Strong & Lightweight Bicycle Bottle Cages for MTB & Road Bikes: Includes Multi-functional Tool & 4 Stainless Steel Screws by Robert Xayamonty

This bottle cage is good and fits most standard bottles. I had to apply some pressure to close the bottle I bought. It's strong enough where it allows you to adjust the pressure. It comes with set screws. The tools/hex wrenches/screwdrivers etc that come with the product are cheap stuff but can probably get you out of trouble. I recommend buying a quality set. The big problem is that they don't fit in the holder because the wrench doesn't fit between the holder's teeth. You will need a T-key, which you can buy from many places.
