Square Taper Crank "ACHT"

PROJEKT 1919 Square Taper Crank "ACHT" - LIMITED RELEASE 1

For over a century, we have crafted premium cycle components in our factory in Ennepetal, Germany. The "ACHT" was designed to honor that heritage. Produced in a very limited quantity, it marks both a tribute to our past and the first product available for consumers to purchase directly from Alfred Thun GmbH.

The "ACHT" pairs the classic square taper interface of earlier eras with a fully modern design: 100% CNC-machined from high-strength 7075-T651 aluminium, featuring the contemporary SRAM 8-Bolt standard chainring interface.

To honor more than a century of heritage in cycle component manufacturing, we’re releasing 107 sets of "ACHT" as a limited release, one for every year of production at our factory. Each pair is hand-polished, finished in a clear Type II anodize, and identified with its individual production number.
