New key enhancements to our signature Mechanism Bibs. Updated straps give extra stretch and breathability using a mesh-structured fabric. A higher front rise provides a more comfortable fit, and the new front mesh offers the same breathable and durable properties as the back mesh of the bibs. A new zigzag in-seam chamois stitching minimizes friction between the seam and saddle and provides higher durability. Constructed from compressive textiles with high elasticity, the Mechanism Bibs are fitted to match your optimal riding position without restricting mobility.
