SRAM GX Eagle XG-1275 12 Speed Cassette
Description
The XG-1275 GX Eagle cassette provides all the benefits of 12-speed Eagle but without the huge price tag found on the X01 and XX1 models. SRAM's Full Pin technology permanently connects the precision-engineered steel cogs with high-strength stainless steel pins, resulting in an open design with similar performance to the high-end cassettes with only a small weight penalty. X-Glide 2 technology provides quick and precise shifting up and down the cassette, even while under load, and the 10-52t option provides riders with up to a whopping 520% gear range.
Who's this item for: The GX Eagle cassette is for riders that want all the benefits of a 12 speed Eagle cassette at a wallet-friendly price point. The GX range is for people that much prefer to ride their bike than sit there looking at it.
Number of gears: These are 12-speed Eagle cassettes.
Weight: Approx 70-80g heavier than XX1/X01 cassettes.
- 10-50t: ~448g
- 10-52t: ~452g
Materials / construction: The GX Eagle cassettes use a fully pinned construction to permanently connect the steel cogs and alloy large cog with high-strength stainless steel pins, resulting in an open design with similar performance to the high-end cassettes with only a small weight penalty of approx 70-80g.
Cog-tooth span: Only the largest cog differs between the 10-50t and 10-52t cassettes.
- 10-50t: 10t, 12t, 14t, 16t, 18t, 21t, 24t, 28t, 32t, 36t, 42t, 50t
- 10-50t: 10t, 12t, 14t, 16t, 18t, 21t, 24t, 28t, 32t, 36t, 42t, 52t
Freehub mounting style: XD Driver only.
Other component compatibility: SRAM has redesigned the new derailleurs to work with the larger range of the 10-52t cassette and it is their official stance that only the new derailleurs with 520% printed on the rear of the cage are compatible with the 10-52t. If you have an older Eagle derailleur without 520% printed on the cage you should stick with the 10-50t cassettes.
Best paired up with an Eagle chain.
Pros: Awesome range and shifting performance at an affordable price point.
Cons: There is a small (70-80g) weight penalty associated with the pinned construction.

Better than Expected

I upgraded my derailleur and trigger last year to GX. I was very impressed with just how much they improved gear changing and the overall ride. It was time to give the bike a big service and decided to upgraded the cassette to GX as well. As a disclaimer, this meant a new rear wheel as mine was not XD compatible, I changed the chain and cables (internal and external) too. The difference was better than expected, gear change is smooth and precise, while the smaller gear gives more speed for gravity driven descents .
It really is a joy to ride, both up and downhill now.
Fast delivery and well packaged.

Comprehensive catalog of parts. Managed to snag GX Eagle Cassette which are hard to come by in these strange times. Fast delivery and well packaged.
Nifty shifty

Decent shifting performance, relatively light and doesn’t break the bank..
Expensive but very durable

My first one went nearly three years and I probably could have run it longer but I let the chain stretch too much.
