Description of Corki 31.8Mm Aluminum Alloy Bicycle Seat Post Clamp Collar With Titanium Alloy Screws

SEATPOST & SADDLE - A good seat post and saddle are crucial components for every bike. Whether you're having a casual ride or doing 100km, the comfort and positioning of your seat rely upon an even more crucial component. The trusty yet neglected seat post clamp. A high-quality Seatpost clamp tightens quickly. Doesn't need adjusting, and secures your seatpost without movement, even under your full seated weight. DESIGN - There are two crucial jobs of a seat post clamp. Firstly, the seat post clamp must stay securely positioned on the bike frame. The Corki Cycles seat post clamp was designed with a small notch which allows it to stay in place on the frame tubing. Secondly, the seat post clamp must hold the seat post secure without slipping. To ensure an extra tight secure seat post we used a titanium alloy screw for the clamp. INSTALLATION - Apply up to 6Nm of torque to clamp the seat post into position by tightening the Allen key. Position the seat post clamp with the screw facing front or at the back to your own preference. COMPATIBILITY - When fitting a new seat post clamp it is extremely important to order the correct size diameter to match your bike frame. Failure to do so can mean a poorly fitting and performing seat post clamp. The Corki Cycles seat post clamp comes 31.8mm diameter seat post clamp is suitable for 27.2mm-28.6mm diameter bicycle seat tubes. To fit add a little grease to the seat post clamp as well as your seat post and tighten securely. MATERIAL - The Corki Cycles seat post clamp is made from Aluminum 6061. Weighing only 9g/0.31 ounces together it's ultralight, strong, and durable. Each seat post clamp is made with a CNC machine ensuring precision and quality.

Seems to work fine.

You dont need to tighten seatpost collars to 6nm m. Thsts just the max gor this one. I have mine tightened to 4. It also matches my taillight :)

Pros
  • Didn't have enough tork
Cons
  • The corki seat post clamp might not provide a secure enough fit for aggressive riders

Alloy screw not a good choice

After installing this clamp and tightening it to specs, my seat post kept slipping downward. I used carbon fiber assembly gel and tightened this clamp to specs. it still didn't hold. I've tightened it beyond the recommended torque, gotten it to hold, but only after the head of the clamp screw nearly distorted. It is light, but I think it is a bit under-spec'd for what it is supposed to do and the ti screw may not be a good idea.

Pros
  • quality product& fit well ,light weight
Cons
  • The corki seat post clamp might not be durable enough to withstand heavy use

Super light weight, but the clamp was a little oversized. I had to shim it to prevent the tabs from touching.The clamp is a little "short" and doesn't provide enough area/clamping force to the seat tube. I torqued it to the required torque, made sure the tabs weren't touching, and my post still slipped about 1" over a 50-mile ride. Not fun!I like the Ti bolt, but I think it's mis-sized as well. A little larger bolt would help the clamping torque.

Pros
  • Much lighter, smaller footprint, and better looking
Cons
  • The look and design of the product might not be suitable for all bike styles

Light but weak best in my review

Had this on the bike for a year. Adjusted it maybe 5 times always with a torque wrench. The last time I moved my seatpost and retightened it last month, the Ti bolt broke into 2 pieces with half the bolt stuck in the aluminum part. And yes the thread was fully greased.

Pros
  • Great product
Cons
  • The product might require special tools and knowledge to install, making it difficult for beginners or inexperienced bike owners
