The Trail One Seat Post Clamp we wanted to achieve two things; a strong clamping force to hold your seat post in place, and for it to look really good while doing it. Our precision CND’d clamp is made from 6061 alloy and features an M5 bolt. On the bolt we have a convex washer that helps self-align the bolt with the anchor nut, so even at max torque the bolt or clamp isnt being pinched or binding. Aesthetically we wanted this seat post clamp to match many of our products, so the chamfer and cutouts mimic the lines and angles of our stems and pedals. 

Available in Black or Silver (Raw) to match our other products, and currently is available in a 34.9mm diameter. The entire clamp, bolt and nut weighs in at 18g. At Trail One Components, we believe in keeping your products feeling like new for as long as possible. Make your parts last longer while keeping more bike products out of the landfill.

We are on a mission to make phenomenal products that support the sport of mountain biking. For every Trail One Seat Post Clamp sold, we will add $1 to the Trail One Treasury. The Treasury will periodically award funds to deserving trail networks. We exist to support the trails we love, the people that take care of them and to make your riding experience exceptional.
