XG-1199 XX1 Cassette 10-42t

1x drivetrain dedication by design, this is SRAM's XX1 line. Simple. Light. Durable. Less is more.

Featuring a wide, 11-speed gear range of 10-42t--without sacrificing optimized, even steps. A single-unit cassette made with SRAM''s X-Dome technology, it requires an XD driver body (currently only SRAM and DT Swiss options exist) which provides superior wheel connection.

• 11-speed (10-12-14-16-18-21-24-28-32-36-42)
• Requires an XD driver body, 6-8g lighter on average
• 260g

X-Dome technology in manufacturing allows for extreme precision and strength with extremely low weight. An open design helps mud clearance--keeping shifting clean and maximizing component life.

The XD driver body is a new cassette driver body design which allows the use of a 10t cog. It improves the overall interface with the cassette''s bearing design, steadies the ratchet mechanism, and produces overall increased stability in the hub connection.

The SRAM XX1 Rear Derailleur is pretty much required to run this cassette, at least as far as we know right now.
