Just like the X0 and XX Transmissions, the GX Transmission is a wireless twelve speed drivetrain with a 1x ring up front. Inside of the derailleur you’ll find an updated clutch that’s stronger than the previous GX AXS clutch, and all kinds of algorithms running the show behind the scenes to make every shift crispy. Just like before, there’s still a 520% gear range to winch you up the steep climbs and still let you put power down on the fast descents. And don’t worry about those river crossings because this system is just as waterproof as before, with a full IPX7 rating to keep all those robots safe.

Included in a GX Transmission groupset is a derailluer, cassette, chain, crankset with a chainring, and a pod controller.

Breaking derailleurs is a part of mountain biking that always sucks, but SRAM is making it suck less than before with easily replaceable parts on the GX derailleur. Now if you bend or break your low hanging cage, you can buy a replacement for a fraction of the cost of your derailleur to get you rolling again. Or if you’re trying to keep the body of the derailleur looking fresh, you can also replace the skid plates and outer link in case you scratch them or break them. But good luck breaking this derailleur! The new direct mount design makes it incredibly robust and will shrug off hits that would otherwise break a traditional derailleur or hanger. There’s also the same Overload clutch that lets the derailleur scooch in during an impact and then pop back out again when it’s safe, kind of like a game of whack a mole.

After so many years of easing up on the pedals through a shift, it’s tough to reprogram your brain to keep smashing on the pedals while the chain climbs to its new home, but you’re rewarded with a smooth and quiet shift every single time.

The new GX chain got a fresh haircut for this iteration and shares the flat top look for increased strength to weight ratio and great performance. Every link is held together with solid pins, which increases durability and is tough enough to hold up to the abuse Ebikes are known for throwing at drivetrains. By moving material from the sides of the chain to the top, SRAM has made this chain even stronger than before without adding weight to it, a welcome change in my opinion.

Made out of forged aluminum, the brand new GX crankset is a no nonsense affair, with removable bashguards protecting the chainring from rock strikes or big cases. You might recognize these bash guards from the X0 Transmission, and that same technology has made it’s way to the GX version. You can remove one of the bashguards to just keep the one that’s on the underside when you’re pointed downhill, or keep them both on if you’re crazy enough to switch your feet throughout a trail. That chainring is attached to the crankset by 8 bolts, which seems like overkill, but you’ll have peace of mind that your chainring won’t fly off and turn into a ninja star.

GX Transmission is made for the masses, bringing all the performance everyone loves about the Transmissions at a more affordable price point. If your bike has a SRAM Universal Derailleur Hanger and you want the best shifting on the market, the GX Transmission is undoubtedly your best bet. Just remember to keep those batteries charged!
