\n\n

SRAM\u2019s SX Eagle and Shimano\u2019s Deore M6100 are entry-level 12-speed mountain bike drivetrains.\u00a0<\/p>

Both 1x drivetrains are pitched at similar price points, competing to be the top choice for budget-conscious riders looking to make the jump to 12-speed shifting.\u00a0<\/p>

In this article, we explain the features, upgradability and compatibility of the drivetrains, giving you the information you need to choose between the two.\u00a0<\/p>

SRAM SX Eagle and Shimano Deore M6100 at a glance<\/h2>

SRAM SX Eagle<\/h3>

SX Eagle is the most affordable 12-speed mountain bike drivetrain<\/a> in SRAM\u2019s line-up. It\u2019s not available as a full groupset in the aftermarket, but the components can be bought individually.<\/p>

At full retail price, the SX Eagle drivetrain<\/a> comes in at around \u00a3297.99 (excluding chain and bottom bracket). However, making the most of the heavy discounts found on many online bike shops, the drivetrain can be bought for less than half its original RRP.\u00a0<\/p>

Shimano Deore M6100<\/h3>

Deore M6100 is Shimano\u2019s affordable 12-speed groupset, with a reputation for being reliable. It sits below the slightly pricier Shimano SLX groupset.<\/p>

It\u2019s priced similarly to SRAM\u2019s SX Eagle at around \u00a3285.95 and packs in a lot of value for money. Bargain hunters will be able to save a considerable chunk of the full retail price. The Deore groupset is often heavily discounted in numerous online shops.<\/p>

SRAM SX Eagle vs Shimano Deore \u2013 how do they compare?<\/h2>

Shifters<\/h3>

SRAM\u2019s SX Eagle shifter features a largely plastic design. It uses the brand\u2019s X-actuation design, enabling you to downshift multiple gears with one push. A single-click version is also available. The SX Eagle shifter misses out on SRAM\u2019s Matchmaker clamp<\/a>, which enables you to mount your shifter to the same clamp as your SRAM brake, improving cockpit ergonomics.\u00a0<\/p>

Shimano\u2019s Deore shifter is also made mainly of plastic to keep costs down. It features Rapidfire Plus shifting for a three-gear downshift. Unlike the SRAM shifter, the Deore option is compatible with Shimano\u2019s I-Spec brake levers for a neat cockpit.\u00a0<\/p>

Derailleurs<\/h3>

SRAM\u2019s SX Eagle derailleur<\/a> is basic and, although it\u2019s cross-compatible with the rest of the Eagle range, it lacks some key features. Its biggest letdown is that it doesn\u2019t have a clutch. The SX Eagle derailleur is compatible with Eagle cassettes up to 50 teeth.<\/p>

The Shimano Deore derailleur features a slightly more premium construction and boasts the brand\u2019s tried and tested Shadow RD+ clutch technology. The inclusion of a clutch is a big bonus and shouldn\u2019t be overlooked because it reduces chain slap and improves chain retention. The Deore derailleur is compatible with 12-speed Shimano cassettes up to 51t.\u00a0<\/p>

Cassettes<\/h3>

SRAM\u2019s SX Eagle cassette<\/a> is made of steel. It uses SRAM\u2019s PowerGlide tooth design and features an 11-50t profile.<\/p>

Unlike other SRAM Eagle cassettes (apart from the NX version), it doesn\u2019t use SRAM\u2019s XD freehub standard. Instead, the SX Eagle cassette is compatible with the splined HG freehub body, introduced by Shimano and used for many 8-, 9-, 10- and 11-speed drivetrains. This makes it a great option for riders looking to convert an older wheelset to 12-speed without having to change their freehub<\/a>.<\/p>

The Shimano Deore cassette also features a steel construction, using the brand\u2019s Hyperglide+ tooth design. It has a 10-51t profile.<\/p>

The cassette uses Shimano\u2019s Microspline freehub standard, making it compatible with the rest of the brand\u2019s 12-speed range but incompatible with older HG freehub bodies.\u00a0<\/p>

Cranksets<\/h3>

Both Shimano and SRAM use two-piece cranksets with direct-mount chainrings.\u00a0<\/p>

Shimano\u2019s Deore crankset is available with a 30t or 32t chainring and 160\/170\/175mm cranks.\u00a0<\/p>

SRAM\u2019s SX Eagle crankset comes with a 30t, 32t or 34t chainring and 155mm, 165mm, 170mm or 175mm crank lengths.\u00a0<\/p>

Gear range<\/h3>

SRAM SX Eagle and Shimano Deore are both 1x drivetrains with 12 gears. However, there is a difference in the overall gear range<\/a> on offer from the two cassettes.\u00a0<\/p>

SRAM\u2019s SX Eagle cassette has a range of 11-50t (454 per cent), while Shimano\u2019s Deore counterpart has a wider 10-51t (510 per cent) range.<\/p>

Brakes<\/h3>

The Shimano Deore M6100 group also includes two models of brakes.<\/figcaption><\/figure>

Shimano\u2019s Deore M6100 ecosystem contains two brake models, differentiated by their piston design. Cross-country and light trail riders have the option of speccing a twin-piston brake, which shaves a bit of weight and bulk by sacrificing some braking power over the quad-piston version, which offers maximum performance for trail and enduro riders.\u00a0<\/p>

SRAM\u2019s MTB groupsets are drivetrain-only, and the SX Eagle is no exception. Sitting in a similar position to Shimano\u2019s Deore offering are the SRAM Level Bronze brakes. Also available in twin or quad-piston configurations, these brakes are among the latest entry-to-mid-range offerings in SRAM\u2019s line-up.\u00a0<\/p>

Compatibility\u00a0<\/h2>

As mentioned, SRAM\u2019s entry-level SX Eagle cassette is designed to fit older HG freehub bodies, not SRAM\u2019s own XD standard. This is great news for those looking to keep using their older wheel and hub setup in a change to 12-speed shifting, but it also limits upgradeability down the line because SRAM\u2019s more premium cassettes won\u2019t fit.\u00a0<\/p>

On the other hand, Shimano\u2019s Deore cassette isn\u2019t compatible with older HG drivers, but once you have invested in a Microspline freehub, you\u2019ll be able to use all of Shimano\u2019s 12-speed cassettes going forward.\u00a0<\/p>

So, should you choose Shimano Deore or SRAM SX Eagle?\u00a0<\/h2>

Switching to 12-speed gearing is a big upgrade for any mountain biker and these entry-level drivetrains make it an affordable option.\u00a0<\/p>

We are fans of the reliability and performance of the Shimano Deore groupset and would recommend it to any rider looking for an affordable upgrade to 12-speed, especially if they already own a Microspline-equipped rear wheel.\u00a0<\/p>

While SRAM\u2019s SX Eagle derailleur lacks a clutch and leaves a little to be desired, the HG compatibility of its cassette is attractive to budget-minded riders looking to keep using their old freehub. If possible, we would recommend investing a little extra in an NX Eagle derailleur, which features a clutch and is the next step up from SX.\u00a0<\/p> <\/body><\/html>\n
