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.

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.
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.
