Niner’s RLT 9 lineup consists of three versions—carbon (RDO), steel and alloy. All three of  the Niner RLT 9 are offered in 650b or 700c builds with their carbon fork paired with all models. The Niner RLT 9’s alloy frame is the balance between price, performance and weight, but most impressive is that Niner tests all their bikes to the more demanding test standards that mountain bikes require.
