Wert Cycling aims to be at the forefront of technology and these Wert Catalyst Cranks could be considered a revolution among cranksets (pun intended).

Catalyst Cranks find their heritage in the super-steel MYTH cranks, arguably the most advanced crankset to date. MYTH cranks, designed in 2006, achieved extraordinary strength and stiffness levels from its proprietary construction with Reynolds 953 tubular arms and precision laser welded joints.

In fact, our MYTH crank were so advanced that they were forward-compatible with BB386EVO (five!) years before this standard was even introduced. And our Catalyst Cranks represent yet another decade of technological advancement…

With costly development and manufacturing, and quality control issues related to welding, MYTH Cranks will never see production. However, new advances in Added Layer Manufacturing, a technology we explored back in 2007, opened up new horizons. This technology allows us to produce crank arms capable of coping with the most brutal pedal forces in larger series.  A lack of welds also means fewer quality control issues and ultimately a better product.
