The NX cassette uses Shimanos HyperGlide (HG) freehub body instead of SRAMs XD Driver found on the rest of the brands 12-speed cassettes. Alex then moved back to the UK and put his vast knowledge of mountain biking to good use by landing a job working for MBUK magazine as features editor. The NX Eagles cassette ratios are 11t, 13t, 15t, 17t, 19t, 22t, 25t, 28t, 32t, 36t, 42t and 50t. 
With a 1x crankset, there will only be a single shifter for the rear cassette, which saves some space for all of the other gadgets that will come into play, like dropper post controls. 
The XX1 was designed for cross-country biking or for the really serious weight weenies of the world, and why SRAM spared no expense at cutting the weight from this system. The SRAM X01 drivetrain and XX1 drivetrain are essentially the same, but SRAM has made a few tweaks to make them better serve their assigned purposes. I have close to 800 miles on my NX setup, no issues so far. Suffice it to say, you are looking at some serious kit. The derailleurs parallelogram design dubbed X-Horizon by SRAM is claimed to stop the derailleur from moving vertically closer to or away from the cassette. Since working for MBUK, Alex's focus has moved to bike tech. As your legs press into the pedals, they add pressure to the cranks (the shafts that connect the pedals to the front gear). The Deore derailleurs clutch is adjustable compared to NXs non-adjustable version and controlled the chain better than NX. The technology that was once only in the super high-end pieces of kit is slowly making its way down to the more affordable options, which is a win for everyone. The gold on the cranks does look really good, though! If you are looking to get XTRs 12-speed cassette, you will have to upgrade to Shimanos Micro Spline freehub to accommodate the larger cassette. The SRAM NX Eagle PG-1230 cassette differs from GX, X01 and XX1 Eagle cassettes in that it uses Shimanos HG freehub body standard instead of SRAMs own XD Driver. ** First, a note on mountain biking jargon: All of the components listed below as part of the drivetrain collection are known as the groupset, groupo/gruppo, or group. I have a Deore 1x10 on my old 26er and a Deore 1x12 on my other trail bike. Shimano has now been in the cycling game for a century. With the Deore XT, we also see the first compatibility with Shimanos Di2 electronic groupset. The derailleur worked well with the chain and chainring, and I suffered no dropped chains during the test period. The SRAM X01 is designed and built for trail and enduro racing, so SRAM beefed up the cranks and the rear derailleur to make them more suited for rougher trails and enduro-style riding. Shimano Deores build quality appears to be better than NXs, too. The addition of the 112 cassette has also introduced the need for Shimanos Micro Spline freehub, so it will no longer fit on the fairly standard Shimano Hyperglide freehub. Furthermore, and similarly to GX Eagle kit, the DUB bottom bracket bearing preload lock ring came undone, causing the cranks to feel loose. NX Eagles shifting isnt as crisp as Deores, where each shift has significantly more definition. Still, I found this made the gears more usable because large changes in cadence or speed werent required to compensate as gears were shifted. He's one of BikeRadar's lead testers, knows how to push bikes and products to the limit, and wants to search out the equipment that represents the best value for money. And would not buy a sram product, unless it came stock on a. Bike they are over priced after market. If youre upgrading an older bike from 9-, 10- or 11-speed with an HG freehub body, thanks to NX Eagle not using an XD Driver with its cassette, its by far the least complicated and most cost-effective way into SRAMs Eagle ecosystem. So until the 113 comes out, this is as good as it gets. Impressively, the NX Eagle rear derailleur managed to control excessive chain movement well, given the required chain length to accommodate a 50t cassette sprocket. Built like a tank, wide enough range of gears, and cheap to buy up front as well as replacement parts later on. Better shifting ? The AXS system for mountain bikes was introduced in 2019. It would be impossible for us to pick the ultimate winner between SRAM and Shimano. The chains inner plates are totally smooth to help reduce friction and wear, known by SRAM as Flowlink. Because the lock ring is plastic, its not possible to get a sufficient amount of tension in either the lock ring or pinch bolt to keep the ring tight for any duration of time. I wouldn't recommend SX. I also found the cranks edges to be quite square, which did cause a small amount of discomfort when rubbed against my feet or ankles. 
If the current Deore lives up to it predecessors, it will still shifting like new when all that is left on earth is cockroaches, sturmey-archer hubs and HP laserjet 4s. In reality, Ive been able to reuse SRAMs PowerLocks more than once, despite SRAM not officially recommending this. |, USD $375.00 As a company, Shimano makes up approximately 80% of the global road-biking components market, but only 20% of the global mountain-biking market. The NX Eagle derailleur is only compatible with up to a 50-tooth cassette sprocket, so accessing SRAMs 520 per cent 10-52t gear ratio will require additional investment in a GX Eagle or higher derailleur. This, SRAM says, makes ghost shifting impossible because the derailleurs body can only move horizontally as gears are changed rather than by bumps causing it to jump about. Higher-end shifters also allow for faster gear changes by offering multiple gear drops with one thumb push. These drivetrains offered a 500% gear range, eliminating the need for 2x front chainrings. SRAM has built NX Eagle to offer a 12-speed drivetrain at a more affordable and accessible price, but in doing so has compromised performance, especially when compared to the more modestly-priced Shimano Deore and slightly more expensive SLX, which is ultimately where Id spend my money. To get into this world of elite enduro riding, you are looking at a $1,285 investment for the drivetrain (excluding brakes). The horizontally positioned cable port means a large loop of outer cable isnt needed at the rear dropout, helping to keep the bike tidy and reducing the chances of it getting snagged on rocks, etc. An upgrade kit will set you back $600, but it gives you a glance into the world of the super expensive bike market that always seems just out of reach for us ordinary folk. The whole setup is mainly made of steel. Sign in to manage your newsletter preferences. The single rechargeable battery the Di2 system uses has 1,000-2,000km (621-1,242mi) of battery life. While Shimano may be slower to innovate, they have been around for a long time.

Following SRAMs instructions to correctly size the chain, it was too long when set in the highest gear and the suspension uncompressed. 
If I was upgrading the drivetrain on my bike and had access to or budget for a Microspline freehub body, I would choose Shimanos M7100 SLX over SRAMs NX Eagle. This game-changer is something we all take for granted now. The DUB axle and bottom bracket NX Eagle crankset is made from forged aluminium. This allows the cassette to fit the Shimano HG freehub, so you do not need to replace your entire wheel to accommodate the 12-speed cassette. For the price, NX Eagle faces tough competition from the likes of Shimanos 12-speed M6100 Deore groupset, which is where I would spend my money. Shimano has three subsets of mountain bike groupsets: Downhill, Daily Drivers, and Mountain Biking. Shimano resisted initially, sticking to the 2x drivetrain, which has a greater gear variety. In an industry where the technology is practically the same, it truly comes down to individual feel and preference. The DUB system cranks have a bottom bracket bearing preload lock ring on the non-driveside to help set bearing tension. Both Shimano and SRAM have shifters that can downshift multiple gears in a single stroke. Shimanos Deore retails for 285.95 / $297.95 / AU$539.50, which is significantly cheaper than NX Eagle. What they are known for is HOLLOWTECH, a very durable and lightweight setup that employs hollow aluminum crank arms. One of SRAMs most notable influences was the reintroduction of the 112 drivetrain to mountain biking. Setting the derailleurs b-tension, as per all of SRAMs Eagle groupsets, needs to be done perfectly to ensure shifting performance, otherwise shifts can become lazy and the chain noisy on the cassette. The rear cassette is connected to the rear wheel via a freehub, which gives the pedaler momentum. This is where SRAM enters the game. Shimano introduced the first electronic drivetrainthe Di2 systemin 2009 (for road bikes only). We have finally reached the cream of the crop. The chainring for the XX1 comes with a large range of teeth from 28-40t, offering the rider lots of options to fit their riding style. The cranks are direct-mount chainring compatible where the splined chainring is fastened in place using three Torx T25 bolts and are fitted with SRAMs X-Sync 2 Eagle narrow-wide tooth profile chainring thats claimed to reduce the chances of dropped chains. Since I'm switching from 3x8 idk if 1x10 will be enough for me that's why I'm debating whether to buy it or not, Press J to jump to the feed. SRAM brought the 1x drivetrain back into the mainstream with the XX1 group. The shifter is the same, coming with Shimanos Rapidfire Plus, which offers multiple gear shifts in a single motion. Some of the newest shifters can now be controlled entirely by your thumb, allowing your index finger to remain on the brake. Durability is always a concern when berm bashing on your mountain bike. 
This is less of an issue with GX models and above. With the introduction of their Eagle line, SRAMs options for riders have almost doubled. I just upgraded to gx with a nx cassette but if I was starting fresh, 90% sure I would go shimano. The SX Eagle is the most budget-friendly Eagle drivetrain offered by SRAM. Found on the bottom of drop handlebars for road bikes, it made for more effortless shifting. The black cassette coating resisted rust well and cleaned up with a small amount of scrubbing. 
Starting from least expensive to most expensive: The Altus is the groupset that you will find on entry-level mountain bikes. Many riders trust the quality that goes along with their storied history. For those keeping score at home, this range is better than 210 drivetrains can offer and has fewer moving parts to worry about. To fit SRAMs GX Eagle and above drivetrains, youll need SRAMs proprietary XD freehub body (10-50t/52t). One of the hottest pieces of new technology is the electronic shifter or controller. First created by Shimano, their Di2 electronic drivetrain was impressive but still required wiring throughout the system.
