A simple yet perfect part with a beautiful CnC’ed finish and in a colour of your choice, our cSixx Seatpost Clamp is the perfect addition to your bike.

Designed and manufactured completely in-house at our factory in Cape Town, we pride ourselves on our excellence in design and manufacturing.

With our commitment to Vertical Integrated Manufacturing and our state-of-the-art facility, we are able to produce high-quality products with all processes in-house, that are built to last. 

Made from the finest materials available, in this case, a 6082 aluminium Seatpost Clamp body, 7075 aluminium Rotational Nut and a Stainless-Steel bolt, the cSixx Seatpost Clamp is durable, lightweight and has a smooth tightening action, ensuring perfect fit, form and function for your bike.

We focus on designing and building a product that lasts longer and is more durably, not necessarily the lightest.  South Africa has some of the toughest conditions in the World for cycling and that shows in the durability of our product range.
