Looking for a super lightweight no-nonsense carbon seatpost to take the edge off? We've got what you're looking for at a great price. Our 650 series post offers an even lighter carbon/titanium seat clamp system than our 600 series post.   Wren Carbon seat posts are 100% hand-laid carbon.  Over 45 individual carbon flags are hand positioned into our proprietary molds to ensure a lightweight yet strong seatpost. Every Wren seatpost is hand-inspected and machine tested before shipping.   Wren Carbon seatposts may be cut down to fit your specific length. We recommend taping the area to be cut and using a 32TPI hacksaw blade.
