E-Thirteen TRS Plus Cassette Parts - XD Driver - 33-39-46T - 11 Speed PDP|Colour 4 and 5mm hexGenuine E Thirteen replacement parts for the TRS Plus Cassette. These are Gen 2 parts and now use the T25 pinch bolt for attachment to the freehub body, rather than the lockring system the Gen 1 cassettes used. Please note: The Gen 1 TRS Plus cassettes were made up of three parts. These spares are for the Gen 2 TRS RACE cassette which now uses a two part system. Unfortunately Gen 1 parts are no longer available from E Thirteen.
