Penumbra

Penumbra marks MK1’s entry into the ultra-wide category, pushing their design language further than ever before. With a full 55mm diameter and 55mm width, it delivers an expansive catch zone that makes large, complex tricks feel more accessible and consistent.

Built from 7068 aluminum and paired with stainless steel rims, Penumbra offers strong spin power and stability while maintaining a surprisingly light feel at just 64 grams. The rim-focused weight distribution provides long, steady rotation with a controlled, confident presence on the string.

Despite its size, it remains agile and responsive, balancing power with playability for modern competitive styles.

Each colorway is a signature edition representing members of the MK1 team, adding a personal touch to MK1’s most ambitious wide design yet.
