Review on Topeak QR Water Bottle Cage Mount (4.3 x 1.7 x 3.7-Inch) by Ron Patel

So happy to find this! I like my rear rack (Allen Sports Compact 1 bike model) but the downtube bottle cage rests directly on the center support piece, which flexes the cage and makes it difficult to keep the bike securely in place. This part solves the problem by allowing me to easily remove the bottle cage. A bonus feature I later discovered: having a pump mount that fits under the bottle cage also allows me to easily move a pump between multiple bikes!
