SRAM GX groupsets unleashed!

After a couple of teases, SRAM has finally lifted the veil on the all new GX groupset. It’s designed to ‘bring the power of riding to everyone, everywhere‘. Which to you and me means it’s a mid-level groupset, forgoing the carbon and bling, and reduces the price to a level that more of us can actually afford.

There’s some magnificent flannel in the press release (‘For every bike, there’s a rider. A rider who builds it. A rider who knows it. And ‘introducing GX, the drivetrain for people who love to ride without restraint‘ – all internally spoken in a gravelly American accent, natch), but what it boils down to is a variety of different setups: 1×11, 2×10 or 2×11. Yep, that’s a 2×11, with a 24T granny and a 42T large rear sprocket. So HOW SPINNY??

In the granny gear, you’ll be running 15.8 gear inches, which (for those who don’t know) is the equivalent of a penny farthing with a front wheel a tiny bit bigger than an LP record. Which is really, really teeny. That’s some steep hill. The press stuff tells us that the 2×11 groupset has a 630% gear range.

So, where were we? Ah yes. Well, there are all-new shifters – both trigger and Gripshift, mechs front and rear, chainsets and chains to accommodate the huge range of options available and keep the price reasonable. There are different levels of chainset within GX, too – the GX1400 uses Open Core Technology (it’s hollow) and the GX-1000 is machined (the chain sets are machined out at the back).

One of the things about previous iterations of SRAM’s 1×11 drivetrains was the high cost of the cassette. Here are details on the GX offering, according to the press release: “FULL PIN™ technology uses eleven lightweight, stamped steel cogs held together with 123 high-strength stainless steel pins. The result: a cassette that’s extremely light, durable and equipped with SRAM’s super wide 10-42 gear range that’s a perfect fit for any ride. The open design similar to our X-DOME™ cassette aids in mud clearance, giving you cleaner shifting performance and longer component life.”

The 11 speed cassette needs an XD hub (no surprises there) and it weighs a claimed 394g – for reference the (machined from one block) XX1 is claimed to weigh 260g and the X1 weighs a claimed 315g. Mind you, the new 11 speed XTR weighs 328g. So its heavier, but only by a Mars bar or so. And the price is (considering the engineering needed and its complexity) a very reasonable £115. We should be seeing it around July 2015.

Here are the pricing details in all your denominations:

And because there’s SO MUCH information, and SO MANY buzzwords, here’s the (almost 3000 words, people – grab a brew) press release, for all you techno-weenies to pore over. Remember to read it in a gruff American accent (in your mind, or out loud, if you’ve got understanding colleagues), and you’ll be fine.

TECHNOLOGIES

ALL FOR ONE
SRAM 1x™ is the only one you need: less weight, better chain control and the ability to sync up with any riding style. Our 1x drivetrain philosophy focuses on optimizing how components work together—crank to ring, tooth to chain, shifter to derailleur, derailleur to cassette, and cassette to wheel. No matter where you ride, no matter what you’re up against, SRAM 1x™ takes you further.

X-SYNC™
SRAM X-SYNC™ 1x chainrings provide the highest level of performance and durability. The SRAM X-SYNC™ tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC™ chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC™ chainrings are an integral part of the SRAM 1x™ drivetrain. Accept no imitation.

X-HORIZON™
This rear derailleur’s “straight parallelogram” design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears.

ROLLER BEARING CLUTCH™
ROLLER BEARING CLUTCH™ technology eliminates derailleur bounce and chain slap without sacrificing precision.

CAGE LOCK™
With CAGE LOCK™ technology in the rear derailleur, wheel removal and installation— as well as chain installation—becomes faster and simpler. Just push the cage forward to create slack and lock it into place.

X-DOME™
The revolutionary machined design of the X-DOME™ cassette uses the same gruelling manufacturing techniques that produced the PowerDome road cassette. With X-DOME™, ten of the cogs are CNC machined together out of a single block of billet steel, creating an incredibly lightweight, precise and strong cassette.

FULL PIN™
FULL PIN™ technology uses eleven lightweight, stamped steel cogs held together with 123 high-strength stainless steel pins. The result: a cassette that’s extremely light, durable and equipped with SRAM’s super wide 10-42 gear range that’s a perfect fit for any ride. The open design similar to our X-DOME™ cassette aids in mud clearance, giving you cleaner shifting performance and longer component life.

XD™ DRIVER BODY
XD™ is a cassette driver body design that allows the use of a 10-tooth small cog and provides an improved interface with the cassette.

X-ACTUATION™
Developed specifically for SRAM 1x™, X-ACTUATION™ keeps shifting sharp and consistent across the entire 10- to 42-tooth cassette.

SPEED METAL™
Full metal, 11-speed indexing keeps shifting crisp and precise with Grip Shift.

ROLLING THUNDER™
Three rows of ball bearings provide zero friction or play—reducing the force needed to shift and promoting long-term performance under all weather conditions with Grip Shift.

JAWS™
Once the Grip Shift shifter and grip interlock securely, forged aluminum clamps on either end reinforce the assembly by locking tightly to handlebar.

JET™
With durable JET™ black finish, the cassette looks as tough as it performs—ride after ride. JET™ finish provides a higher level of corrosion resistance.

GXP
GXP’s Gutter Seal design cuts friction, durability and weight—improving both feel and performance.

BB30
Besides serious weight savings, this bottom bracket means narrow Q-factor, more ankle clearance, greater bearing durability and stronger crank construction.

SRAM X-SYNC™

A DEVELOPING STORY

MODERN MOUNTAIN BIKERS RIDE HARD, OVER UNPREDICTABLE TERRAIN, IN ALL KINDS OF CONDITIONS. SO EVERY DETAIL MATTERS.
When SRAM’s engineers first turned their attention to X-SYNC™, they began by examining the multi-speed, single-ring systems that were already on the market. From inside and outside derailment to mud-clogged gear recesses, the rings presented clear opportunities for improvement. So the engineers started to design—and redesign. Each iteration of the new chainring went to the field for trial runs. And from all of this came X-SYNC™, MTB’s first wide tooth, narrow tooth chainring.

But wide tooth, narrow tooth alone didn’t cut it. The SRAM team plowed ahead with a single goal in mind: to create a ring that contributed to the SRAM 1x™ drivetrain built around simplicity and durability. Every detail was scrutinized, leading to optimized square tooth geometry. To asymmetric tooth-tip offset. To sharp-tipped teeth that catch the chain at extreme offsets. Chamfers and radii designed for optimized guiding. Enhancements engineered to limit roller movement. And mud recesses that keep the chain clean and moving. All focused on the dynamic bike platform for XC, Trail, Enduro, and Gravity riding. And all part of an integrated SRAM 1x™ system precision-designed so that every aspect of X-SYNC™ works perfectly with the rest of the drivetrain.

The original wide tooth, narrow tooth chainring is the optimized ring for riders who never compromise. X-SYNC™—ONLY BY SRAM.

X-SYNC™
SRAM X-SYNC™ 1x chainrings provide the highest level of performance and durability. The SRAM X-SYNC™ tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC™ chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC™ chainrings are an integral part of the SRAM 1x™ drivetrain. Accept no imitation.

X-GLIDE™
Imagine being able to shift smoothly at any time, no matter what. We’re talking full-power shifts. Up, down, whatever the trail demands. Flawless shifting means you’ll never again compromise your speed and power in unpredictable off-road terrain.
Here’s how we did it: our crank engineers threw away the old standards and developed a chainring geometry from the ground up. They precisely paired the different-sized chainrings and redesigned where and how the chain engages with the rings. By aligning the chainring pick-up rivets to the chain pivot pin—rather than the middle of the chain link—you get double the shift opportunities, providing the fastest-shifting drivetrain.
No more missed shifts, ever. X-GLIDE™ puts you in THE RIGHT GEAR.

EXACT ACTUATION™
EXACT ACTUATION™ helps to simplify/stabilize the uneasy act of balancing rear derailleur hanger design, tight cog spacing and exact cable tension. The result: the easiest index shifting system to set up and it stays that way.
