## Description

desertcart.com : CUNCUI Bike Seat Clamps 2 pcs, 31.8mm Bicycle Seat Post Clamp-Black | Quick Release Seatpost Clamp for 27.2-28.6mm Outer Diameter of seat post, Premium Adjustable Bike Seat Clamp Set of 2 : Sports & Outdoors

Review: Great price and fit well - I like the fact that two of them came in the package for under $10. A lot of the other ones I looked at cost that much or more for one. The color matched the original seat clamp perfectly. It fit right over the downtube on my bike without any issues, have used it for several weeks now and I’ve had no issues with my seat post slipping or anything like that so it definitely has a good quality. May have taken all of 30 seconds to easily install it and the quick release makes adjusting my seat up and down , a breeze. Functions just like it should and fit right on the tube. You have to pay attention when putting it on, as one side of the hole is slightly larger than the other one to keep it from moving out of place. The clamp holds very well and is very easy to adjust the amount of clamping force, just by threading the nut down a touch more.
Review: Great value and gets a job done - Works great. Easy to install and significantly better than the other options, especially considering that you get two

### ⭐⭐⭐⭐ Will Give Height to Bike Seat
*by A***S on May 28, 2026*

The product did at last get here on the 28th after it was ordered on the thirteenth. It said it arrived a week ago. The grip is extremely loose on a wide bike post, but it does fit enough to raise up the bike seat post like I needed it to do. I switched out the bike seat on my park bike, and it was very low afterwards.
