Description

SRAM GX Cassette 10-50t XG-1275 pn 00.2418.078.000

SRAM GX 12sp Cassette 10-50t XG-1275


The SRAM GX Cassette 10-52t features 11 stamp steel cogs as well as the 50t in aluminum.

Featuring an 11-50t range this cassette provides excellent gear range. The GX XG-1275 meets the demands of e-bike and e-mtb riders as well.

This is a popular upgrade from NX drivetrains, however the GX (as well as X01 & XX1) require an XD Driver.

Ensure the best performance of your new drivetrain with proper chain lube procedures. Check out a post on how important the right lube is here!

SRAM 52t vs 50t cassette weight and largest cog

10-52t compared to 10-50t

SRAM cassettes are offered in both 52t and 50t options.

The larger 52t cassettes require AXS or the 520% rear derailleurs.

As expected the machined 52t cassette options weigh in approximately 12g more than the 50t models. The image above shows how the 52t (left) cog has been redesigned with less “rays” with an additional “circle” support on the pin radius of the machined cogs.

Since the second smallest cog is 42t on both options you can expect slightly faster shifting with the 50t option. It’s a good practice to “clutch” shift into the largest ring on your cassette to minimize premature wear.

SRAM XX1 X01 machined cassette vs GX stamped steel

Machined versus Stamped & Pinned Manufacturing

If you compare the SRAM cassette lineup you’ll note that the XX1 XG-1299 and XO1 XG-1295 have the 10-42t, or bottom 11 speeds, made of a one piece machined block steel. A titanium nitrite surface treatment that helps reduce friction with the chain and thus improves the cassette’s service life.

The GX XG-1275 cassette instead utilizes cogs made of stamped steel. These individual cogs are then connected with stainless pins visible from both the front and rear of the cassette.

SRAM XX1 X01 machined cassette versus GX stamped steel weights

Machined versus Stamped & Pinned Weight

Looking at the weight difference between the machined XX1 and X01 cassettes compared to the stamped and pinned GX you’ll find a notable difference.

The52t  XX1 Copper Cassette weighed in at 374g while 52t GX cassette came in 81g heavier at 455g. This translates to a 0.18lb difference.
