🔩 Silverock CNC Dual Size Seatpost Clamp for 27.2/31.8mm and 31.6/34.9mm Carbon Posts Review

Buy a double clamp seat post. You can use as many carbon fiber clutches as you like and the slip WILL remain. Works perfectly. I would recommend!

My seat would slide back and forth no matter how tight I used the one that came with the bike tightened the quick release clamp. Replaced it with this one and now it's hard as a rock. It also required very little dressing. Highly recommended and would buy again.

This is a great clamp. I have an aluminum frame bike with a carbon seatpost, and no matter what I tried the seatpost slipped (tried stainless steel washers, grip paste, rubber plate, nothing worked). I also didn't want to overtighten the fastener and break the seatpost. This double clamp offers a significantly improved clamping without overtightening the screw. I would buy more if I had more bikes.
