The Arch MK4 rims feature an asymmetric design with offset spoke holes to improve spoke angle and create a stronger all-around wheel. Unlike most asymmetric rims that suffer from difficult inflation and poor tubeless performance; Stan’s BST-Asymmetric design delivers all the advantages of a stronger wheel; with no compromises in tubeless performance.
