Assos RS Johdah Ultraz Winter Bib Tights The Assos RS Johdah Ultraz Winter Bib Tights aren’t just ordinary bib tights - they’re an evolution of the iconic JOHDAH platform, now built with the revolutionary DIAMOND softshell textile family, delivering unmatched warmth, protection, and a second-skin fit that eliminates restriction. Whether you’re pushing through snow-laced climbs or hammering out base miles in the bitter cold, these tights ensure maximum output without sacrificing comfort or mobility. Constructed with AEPD S11 tailoring and stabilised by the X-FRAME support system, the bibs move with your body for aerodynamic efficiency and muscle support. The layered Twindeck structure, including DIAMOND ULTRA, DIAMOND MEDIUM, and OSMOS HEAVY, offers stormproof, thermoregulated protection where it’s needed most. Add in Waterskin panels, water-resistant cuffs, and reflective details for visibility, and you have a pair of bib tights that redefine what’s possible in winter cycling. For riders who demand more from every layer, the RS Johdah Ultraz are unrivalled. RS S11 seat pad Featuring an ultrasoft Mineral Tec top sheet, the RS S11 seat pad offers immediate comfort. Quick-drying and with odour-control, this pad also features Assos’ WhirlKrater perforations throughout, creating a flow of cooling air to maintain all-ride freshness. Nine millimetres of shock-absorbing SuperAir foam springs back to its original shape, ensuring it maintains comfort and support as weight shifts during your pedal stroke. The 3D waffle construction is a 3-layer, perforated foam that increases breathability and removes excess weight. Meanwhile, the Goldengate 2.0 design anchors the pad front and back, allowing the pad to move in harmony with your movements, while flexible wings ensure smooth and frictionless pedalling.
