Brand new design - strategically placed toggles to hold your race number and a gel system to securely hold gels horizontally, so they don't bounce out.
NOTE : the belt comes with 3 (three) stoppers only. In most cases, you will only need to use 2, then additional stopper would be as spare. However in some race-bibs that comes in 3 mounting holes, then you may use up 3 stoppers.
