How Does the SRAM XG-1275 10-50t Compare to the 10-52t?

The SRAM XG-1275 Eagle cassette in 10-50t gives a 12 speed drivetrain a 500-percent gear range on a standard XD driver body. Cog steps run 10, 12, 14, 16, 18, 21, 24, 28, 32, 36, 42, 50, so the jumps stay close where you shift most and there is still a big bailout gear waiting at the bottom of a long climb. FULL PIN technology holds precision engineered steel cogs together with high-strength stainless steel pins, which is how SRAM keeps the weight down without giving up strength. The black finish runs across the whole cassette and sits well on any build.

The open architecture borrows from SRAM's X-DOME design and sheds mud rather than packing it in, which keeps shifts crisp and stretches out the life of the cogs and chain together. It works with SRAM Eagle 12 speed drivetrains running an XD driver, and it is not the cassette for an Eagle Transmission build, since those groups use the XS-1275 instead. We stock both gearings of the XG-1275 at the lab, and the 10-50t is the one to reach for when the frame or rear derailleur was specced around a 50 tooth maximum.

FAQ

Does the SRAM XG-1275 10-50t need an XD driver body?

Yes, the SRAM XG-1275 10-50t cassette mounts only to an XD driver body. Wheels built for Eagle 12 speed usually ship with an XD driver already fitted. If the rear hub still carries an HG freehub, the driver body has to be swapped before the cassette will go on.

What is the difference between the SRAM XG-1275 10-50t and the 10-52t?

The SRAM XG-1275 10-50t gives a 500-percent gear range and the 10-52t gives 520 percent. Both cassettes share the same 10, 12, 14, 16, 18, 21, 24, 28, 32, 36, 42 cogs and differ only in the largest one. Choose the 10-50t when the frame or rear derailleur is specced around a 50 tooth maximum, and the 10-52t when the extra climbing gear is worth having.

What cogs are on the SRAM XG-1275 10-50t cassette?

The SRAM XG-1275 10-50t runs twelve cogs in 10, 12, 14, 16, 18, 21, 24, 28, 32, 36, 42, 50. That spread covers a 500-percent range from the 10 tooth top gear to the 50 tooth climbing gear.

Will the SRAM XG-1275 work with SRAM Eagle Transmission?

No, the SRAM XG-1275 is an XD driver cassette for Eagle 12 speed drivetrains rather than for Eagle Transmission. Transmission groups run their own cassette, the XS-1275, so the XG-1275 is not the right part for a T-Type build.

Best For

Best for trail and all-mountain riders replacing a worn Eagle cassette, or building a 12 speed wheelset around an XD driver, who need the 50 tooth maximum their frame or rear derailleur was specced for. The steel cogs and pinned construction are built for long service life, which matters through a Pacific Northwest winter where wet grit works on a drivetrain every ride.
