e*thirteen just announced their second generation TRS Plus Cassettes, including a 556% range 9-50T 12-speed version and a 511% range 9-46T 11-speed offering. Read on for details, plus the first of our photos from Sea Otter Classic…

According to e*thirteen, their new TRS Plus Cassettes feature a revised architecture and provide better shifting. New to the lineup is the TRS Plus 9-50T 12-Speed Cassette, with an unmatched 556% range, weighing in at only 398 grams. The TRS Plus 9-46T 11-Speed Cassette still offers the same 511% range, but now uses 10 steel and 1 aluminum cog. It’s designed to resist wear better than the previous version, which used 8 steel and 3 aluminum cogs. Both have a replaceable aluminum large cog and a pinch bolt for ease of installation. Here are the details on each, along with a few photos from Sea Otter Classic.
