Tired of your seat slipping and twisting on your old straight seat post? Maybe it's time to upgrade to one with an integrated clamp. With a clamp that allows you to easily adjust seat angle, and compatible with any seat that has rails on the bottom, they are a secure way to mount your saddle without pivoting or shifting issues.
Please confirm your existing seat post's diameter before ordering - "close enough" is not good enough and may cause irreversible damage to your frame! You can use a set of calipers, or often find the diameter etched into the post near the minimum depth line.
