About us:


We founded 77designz in 2007. We manufacture specialized bicycle components; our product range includes chain guides for round and oval chainrings and crash plates to protect chainrings from rocks and logs. Further, we have developed one of the lightest yet most reliable and comfortable Enduro cockpits out there. Our products are innovative, race-proven, and reasonably priced; that´s what we stand for with 77designz and Kavenz.

The 77-store:

Over the years, our components division has developed very well. But to be able to offer a wide range of mountain bike products, we also started offering absoluteBlack chainrings after we created the Oval Guide together in 2016. In 2019 we added the tubeless products of TY Bike Products, and with the launch of our bike brand, KAVENZ, it was time to create a multi-brand platform. Welcome to 77-store, the sales channel for 77designz, absoluteBlack, Tire Yoghurt, and Kavenz-Cycles.

What we stand for:

We care about the environment here at 77designz, so we make most of our products locally, and we ship all packages in minimal paper packaging to save the world from plastic. We give our very best every single day so that you can enjoy the time on your bike.

Brief History 

The Begining

77designz was founded in 2007 by three friends in Münster, Germany. Our goal was (and still is) to create a super light, yet highly functional, chain guides for mountain bikes. Our expertise in frame design and kinematics led to the Flatout DH Bike and the CAN EN a 160mm Enduro Bike. Our experiments with cockpits resulted in our iconic DH direct mount stem.

The Relaunch

After some turbulence, we shut our doors in 2014 and sold our existing product line to EMANON. After EMANON filed bankruptcy due to some financial planning mistakes, Giacomo and Stefan decided to relaunch 77designz and develop a brand-new product range. Since its reopening in 2015, 77designz has become a fast-growing, sought-after brand standing for race-ready components that you can trust.
