A Colorado company sees the future of tires on mountain bikes, and they are puncture-proof and airless. Britek Tire and Rubber also envisions mountain-bike riders as being in a far happier mood when they learn they can leave their patch kits and pumps at home. For several years the company has focused its prototyping efforts toward airless tires for automobiles but it is now turning its attention to working on airless tires for mountain bikes. Company founder and designer Brian Russell has several patents and more pending for his dream project, the Energy Return Wheel (ERW). In addition to not having to worry about punctures, he says people will find that ERW can deliver better efficiency.
