## Description

desertcart.com : PLATT Bike Seat Post Clamp Aluminium Alloy Bicycle Quick Release Seatpost Collar 28.6mm / 31.8mm /34.9mm : Sports & Outdoors

Review: Works as Expected, Looks Great - Followed the instructions, measured my seat post hole, and purchased the clamp that matched its diameter range. Perfect fit. I purchased a red clamp to match the red PLATT seat post I also bought; in my case, the reds match. Barely registered to me in terms of weight; it's light. That said, it's also strong. I cranked down on mine, ensuring I didn't turn the night so tight I couldn't seat the lever fully. This thing has my seat post held very tightly, and my seat hasn't even had an inkling it will move at all. Great design that matches the seat post, easy to use and install, and I know it's easy to adjust because I played around with the lever and nut until I was happy with how it held my seat post in place. If you want a bit of functional sparkle (a "farkle," if you will) for your bike, this clamp and a PLATT seat post are a good choice.
Review: Good quality - Very happy with this seat clamp, the color is spot on and works great. Definitely recommend
