The Birdcage is the latest rim from GSport and is now the lightest of their rims. Made of standard 6061-T6 aluminum, the Birdcage utilizes the Ribcage's proven cross-lacing making your wheel more durable and stronger. The beads of rim are hollow, making the rim lighter but still providing strength to the rim. The valve stem hole is offset, so as to not compromise the strength of the rim...and as an added bonus, fitting your pump on the valve stem is easier!
