An ultra light carbon fiber race number holder, cause even a very slight advantage can make a difference.
Yeah, we're obsessed. There, we said it. But it's that slightly maniacal level of obsession which drove us to design and manufacture the Predator Razorback. Designed to fit most road bikes that use a standard, side-pull rear brake, the Razorback weighs only 8g—or about as much as a handlebar end plug. Yet because of the stiffness in the Razorback’s carbon stabilizer, it can improve aerodynamics (though let’s be real here, it’s a small increase) by reducing the flapping and buffeting that often occurs with homemade mounts.
