Fits metric chassis. This bush is suitable for Road and Black Series applications. Made using our range-topping Black 95A durometer polyurethane, these new bushes feature self-lubricating, inner PTFE-lined DU bearings with stainless-steel sleeves. This combination of PU and DU bearings delivers smooth articulation and excellent wear, with the compliance of PU and the high performance and precision of a metal bearing.
