About us:

77designz was founded in 2007. Based in Germany, we manufacture specialized bicycle components; our products include chain guides for round and oval chainrings and crash plates to protect chainrings from rocks and logs. We have won Design and Innovation awards for our Freesolo and Oval Guide chain guides. We have also used our firsthand knowledge and experience to develop one of the lightest yet most reliable and comfortable Enduro cockpits out there. All of our products are innovative, race-proven, and reasonably priced.

Over the years our components division has developed very well, but in order to be able to offer the widest possible portfolio, we also have their chainrings in our program after a joint project with absoluteBlack. Since 2019 we also distribute the tubeless products of TY Bike Products and with the foundation of our own 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 soon also Kavenz-Cycles. 

We care about the environment here at 77designz, so many of our products are produced 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 have amazing rides and go even faster.

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.
