Why consider the ILRC Infinity Seat Bibs? These bibs were designed specifically to take advantage of the patented Infinity Bike Seat design. No bulky pads are needed. 3mm vs 10mm make for a MORE comfortable ride. We were actively involved in the design and testing of this unique product. These bibs are not found in stores, only on the ILRC site. We're the world's largest reseller of the Infinity Bike Seat and we're big fans as well.
