Description

This groupset features SRAM’s revised, optimised and updated “DUB” bottom bracket system, which delivers performance increasing integration between the crank, spindle and bottom bracket. This groupset is perfect for riders seeking performance and future-proof drivetrain compatibility without breaking the bank.

SRAM NX Eagle DUB Chainset:

The NX Eagle DUB chainset is engineered to deliver Eagle 12 speed performance and styling that everyone can enjoy. In addition to the excellent chain retention that’s provided by the X-SYNC™2 chainrings, this chainset provides outstanding power transfer and durability due to the highly advanced DUB bottom bracket system. DUB bottom brackets are available (sold separately) to suit all popular bottom bracket shell types, including BSA (English Threaded), BB86/BB92, PF30, BB386, BB30a and BB Right. 

Chainset Features:

Material: Aluminium (chainring), 7000 series Aluminium (crank arm)
Bottom Bracket Interface: SRAM DUB
Chainline: 49mm
Bolts: Direct mount 
Recommended Chain: SRAM Eagle
Compatibility: All Eagle drivetrains
Weight: 705g (175mm, 32T ring)

SRAM NX Eagle DUB 12-Speed Shifter:

Despite the NX model falling under the “entry level” category, SRAM has still managed to pack in some of its best technologies. These include ZeroLoss™ and X-Actuation™ technologies, which combine to offer instant shifts and sharp shifting across the full cassette range.

Shifter Features:

Material: aluminium/Plastic, Stainless Steel hardware
Compatibility: All Eagle drivetrains
Matchmaker compatible for dropper remote and brake lever integration
Weight: 112g

SRAM NX Eagle DUB 12-Speed Rear Derailleur:

As seen on the top-of-the-line XX1 and X01 models, the NX Eagle rear derailleur also adopts SRAM’s 1x specific X-Horizon™ cage design. This carefully engineered mechanism ensures capacity for the huge 11-50T cassette and compliments the smooth Performance of an Eagle 12 speed system. This derailleur also boasts SRAM’s Type-3 Roller Bearing Clutch™ for unrivalled durability and quiet consistent performance.

Rear Derailleur Features:

Material: Aluminium (cage), Steel (spring, pulley), Stainless Steel (hardware)
Max Tooth: 50T
Compatibility: All Eagle drivetrains
Weight: 339g

SRAM 12-Speed Chain:

At the core of all Eagle drivetrains, the 12 speed Eagle chain is designed and manufactured with SRAM’s Eagle™ architecture. This ensures perfect compatibility with all of the other components in any Eagle ecosystem for highly efficient, smooth and quiet shifting that you can take for granted each and every time you hit the trails.

Chain Features:

Material: Steel
Rivet Type: Solid pin
Compatibility: All Eagle drivetrains
Weight: 278g (126 links)

SRAM NX Eagle 12-Speed Cassette:

SRAM designed its NX Eagle cassette to provide riders with the option of upgrading to 12 speed, but without the need for a hub or wheel upgrade. Ready to fit straight on to standard “splined-drive” freehubs and offering a massive  11-50T range, this cassette gives you the climbing range you need to attack the climbs and the smooth performance to get the most out of your other Eagle components. This cassette is also designed to be durable enough for the extra demands and abuse of E-MTB use.

Cassette Features:

Material: 8 lightweight, stamped steel cogs and 4 high-strength steel cogs pinned onto an aluminium spider
Recommended Chain: Eagle chain only
Compatibility: All Eagle drivetrains
Weight: 615g

Technologies:

X-Sync 2: X-Sync 2 Eagle is the next evolution of SRAM X-Sync technology. The aggressive tooth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-Sync Eagle design reduces friction and the accumulation of mud, grit and grime.
 
DUB Technology: The relationship between bottom bracket spindle and bearing is the core of DUB™ technology. It’s where stiffness meets durability. SRAM took it a step beyond conventional thinking and made everything simpler, by better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this clear system approach that equals better drivetrain performance.  

Zero Loss: The gear cable is engaged instantly with zero loss of movement when you press a shift trigger, every gear change is instant and precise.

Matchmaker X Integrated: You can put everything from your XLoc suspension lockout, your SRAM shifters and brake levers as well as your Reverb XLoc remote, all on two clamps. It's the ideal way to put everything within easy reach and tidies up your bike's cockpit.

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

Roller Bearing Clutch: The Roller Bearing Clutch delivers maximum drivetrain stability even through the most punishing terrain. This stability benefits the drivetrain dramatically, as derailleur bounce and chain slap are eliminated without sacrificing precision

X-Actuation: Developed specifically for SRAM 1x drivetrains, X-Actuation keeps shifting sharp and consistent across the entire cassette. This makes gears easy to index and provides exceptional performance.

X-Horizon: The X-Horizon ‘straight parallelogram' design limits all movement on the horizontal axis, which makes ghost shifting impossible while also reducing shift force. The large upper pulley offset design maintains a constant chain gap across all gears and guarantees faster and more exact shifting.

Flow Link: Ultra-smooth chain inner-plates are completely devoid of square edges, resulting in a chain that engages the cassette and chainring with far less friction, for quieter performance and better wear life. The design allows a narrower overall profile and a flatter outer-plate that can withstand greater shifting angles. This means more consistent chain riveting and enhanced overall strength is achieved.

PowerLock: SRAM chain engineers developed PowerLock as a tool free and consistent way to connect mountain bike chains. While PowerLock does not require special tools for installation, the especially tight tolerances of 10, 11 and 12-Speed drivetrains mandate that each PowerLock is good for a one-time application only.

X-Glide 2: This optimised cassette technology, which has been custom designed for the Eagle drivetrain is the next generation of X-Glide shifting. It provides quick, precise, power-on shifting performance throughout the gear range, and increases chain retention on larger cogs.

Customer Reviews

SRAM NX Eagle DUB 12sp Groupset is rated 3.5 out of 5 by 4.
Rated 4 out of 5 by Daff7 from Great groupset upgrade for a good price I bought this groupset for my 2010 Specialized Hard Rock, which is being completely upgraded, and brought back to life. For this to work, I had to buy a DUB BB too. The SRAM 1x12 NX Eagle groupset is very smooth and the gear shifting is excellent. Fitting it took some time, as I didn’t rush. I followed a few videos on YouTube, to make sure I was fitting parts correctly. It comes with all the bits you need, including the SRAM red plastic B screw guide, which is handy to get that alignment right. The only issue I’ve experienced after fitting the set, is the 11T smallest sprocket on the cassette was making the chain ‘skip’ when pushed hard. I adjusted the high limit screw a little, checked the chain tension and tightened the lock ring some more, and this seems to have fixed the issue. I was also apprehensive about whether I would miss have a 2x or 3x crank upfront, but there is plenty of gear range with the huge 12sp cassette. Climbing is easy now, and the top speed is fine for a MTB.

Rated 2 out of 5 by Anonymous from does the job - but chain is poor Bought to revitalise a vintage (2011) specialized rock hopper when the drivetrain wore out. Had many back and forths between various bike companies about whether it would fit on the existing shimano hub. Wiggle said it would and were right. In fact the cassette is about 2-3mm too long to fit on the hub. But you can get it on there and the small cog seems to have just enough bite on the hub not to slip. And it all fits between the forks ok. It is a bit of a bodge if the truth be told, but works ok so far. I'd never done a full drive train replacement, the instructions (online sram video) are not great. They're basically 'how to replace a drive train for someone who's already done it before'. Plus their example is on the high end xx1 groupset, which is materially different. But watch enough videos, take your time, it's ok. But... the chain is poor. Was fine with weekly usage for a month. Then the first time it went out in the wet (despite be covered with wet lube) it corroded within 24 hours. Surface rust everywhere all over the links. The kmc chain it replaced lasted years with the same treatment without a spot of rust. The nx chain appears to be bare steel of a pretty low grade. The gx chain (which is £2 more) has zinc/oxide coating so _presumably_ is significantly more rust resistant. I'm going to buy that as a replacement and hope for the best. I know nx is the low end group set, but I don't know why sram bothered with such a poor chain - all for the sake of £2 on a £280 purchase. I'm just hoping the cassette isn't made out of such poor quality steel and that doesn't start rusting too.

Rated 4 out of 5 by Brian3000 from Good value for money I have upgraded from 2x10 setup to this 1x12 and it was a pretty simple swap. I went fro pf30 to dub without a problem using a mtb dub bottom bracket. Have been riding with it for a while now and not a single problem.

Rated 4 out of 5 by Tomk41 from Awesome upgrade Fitted along with a dropper and tubeless tires plus sram guide t brakes to my old Stumpjumper. Like a new bike. Cassette heavy and miss the option to change down a gear on both directions on the shifter. However great value and did not need to buy the xd driver and have the cost of a wheel re build.

In order for this to be compatible with your bike, you will need to have a Sram XD 12 speed freehub fitted to your rear hub. You will also need the following bottom bracket for the chainset to befitted.

Would this fit a Giant Trance 4 2017 model?

Would I be able to fit this group-set to my Trance 4 from 2017? (https://www.giant-bicycles.com/int/trance-4-2017)
Asked by: DanielE1997
This groupset will not be compatible with your bike. As the rear of your bike runs a Boost spacing (148), this being the case you'll require this groupset - https://www.wiggle.co.uk/sram-nx-eagle-dub-12sp-groupset-boost/ You will also require a new rear wheel that supports an XD freehub, as well as a DUB bottom bracket to suit your bottom bracket shell requirements.
