⚡ At a Glance
- • Clamping Strength: Secure hold thanks to aluminium alloy construction and a reliable quick-release mechanism
- • Best for: Commuters, recreational riders and anyone needing frequent saddle height changes
- • Not ideal for: Frames with seat tube outer diameters outside the listed fit ranges
Durable, lightweight quick-release seatpost clamp available in three diameters with a hollow design that reduces mass. Anodised finish gives five colour options and improves corrosion resistance.
Fast saddle adjustments - With quick-release lever
Lever operation allows opening and closing of the collar without tools, so the seatpost can slide freely when open and is clamped firmly when closed. The quick-release mechanism locks the collar securely around the seatpost.
Change saddle height on the go in seconds, ideal for multi-rider bikes or adapting to varied terrain.
Lightweight handling - With hollow aluminium alloy design
Hollow machining removes unnecessary material while retaining the strength of the aluminium alloy, yielding a low mass—around 39g for the 34.9mm clamp. The alloy construction balances lightness with structural integrity.
Lower clamp mass helps keep overall bike weight down and improves responsiveness during accelerations.
Corrosion-resistant finish - With anodised colourfast surface
Anodising forms a tough oxide layer on the aluminium, producing a colourfast surface and enhancing resistance to corrosion. Multiple anodised colour options are available.
Maintain a tidy appearance through wet weather and reduce the risk of surface corrosion over time.
