This is one of the most secure seat post clamps currently available. The chance of your seat post slipping when using the Velocite Anchor clamp is about zero.
And you do not even need to over tighten it (3 Nm torque is all it needs).
The clamp is CNC machined out of solid 6061 aluminium and uses two stainless steel bolts to achieve a secure, but gentle hold. Each inside facing edge is carefully chamfered to eliminate any possibility of scratching your seat post.
The Velocite Anchor is compatible with any frame that uses a 31.6mm seat post. The height of the clamp is sufficient to completely cover the entire clamp zone of most frames.
