This is an optional Exotek B5 "Flite" Carbon Battery Strap. This battery strap is made in the USA of premium carbon fiber and weighs a mere 6.5 grams. Thats almost 4 grams lighter than the stock battery strap! Plus, the carbon material is stiffer than the stock molded plastic part and gives your ride that factory team look that will make you the envy of everyone in the pits.
