Assos Bonka EVO Bib Tights

Engineered for the coldest, harshest winter conditions, the iconic Bonkas ensure no amount of weather deters your winter program.

The Bonka has evolved, now constructed with an arsenal of proven winter-proof textiles and our CENTO EVO insert to deliver unmatched levels of insulation, protection, and long-distance comfort. With double-layer protection throughout, these stand in as our most protective bib tights.

For the most demanding winter conditions that relegate all but the most dedicated riders back indoors, the Bonkas are purpose-built to thrive. We began with the same highly insulating brushed-back RX Heavy that’s used in our Winter Bib Tights, but we applied a double-layer construction with our acclaimed 2L Stratagon Ultra around the knees, hips, and thighs for added protection, ensuring the front half of your lower body remains fully protected from sleet, road spray, biting winds, and low temperatures. As with the Winter Bib Tights, RX Light makes up the backs of the legs for added breathability in this high-flex region.

The fit of the Bonkas falls into our racingFit category, which means they’re moderately compressive with their double-layer design. The fabric panels flex with each pedal stroke, as they’re both pre-shaped and sewn to fully wrap and support the upper leg muscles, knees, and calves while in motion. The insert is our CENTO EVO, featuring 10mm of plush memory foam for dependable comfort on every ride.
