– All dimensions listed above are in mm unless otherwise stated.
– Geometry is designed around a 522mm axle-to-crown length fork (ie 130mm travel and 42mm offset) to give an aggressive & playful trail geometry, although the frame can be fitted with both longer (140mm) and shorter (120mm) suspension forks depending on the desired riding style.

We’ve put together a range of build kit options from component suppliers we trust that complement the riding style of the new Yo Eddy. Below you’ll find the various options from each category that can be combined to put together your ideal build.
