The Truvativ Descendant Carbon Eagle Dub is the highest-performance option in this lineup, combining a full carbon fiber arm construction with SRAM’s DUB spindle and an integrated X-SYNC 2 direct mount chainring. At 555 grams, it sheds significant rotational mass compared to aluminum alternatives while maintaining the torsional stiffness needed for aggressive enduro riding and hard cornering exits. The Boost 52mm chainline aligns precisely with 148mm rear hubs, eliminating chain rub and improving shift consistency under load.

Riders upgrading from entry-level aluminum cranks report an immediate reduction in pedal feedback vibration and a noticeably stiffer platform when sprinting out of berms. The included 32T X-SYNC 2 ring features alternating tooth profiles that actively shed mud and maintain chain engagement even in wet loam conditions. The carbon arms are wrapped with a protective clear film that prevents trail debris from chipping the layup — a detail that extends the finish lifespan significantly.

Installation requires a DUB bottom bracket specific to your frame’s shell standard, and the crank arm preload must be set with the DUB adjustment ring according to SRAM’s 0.5–1.5 Nm torque specification. The carbon interface is intolerant of over-torque, so a calibrated torque wrench is mandatory. For riders targeting a weight-weenie build or those who routinely push their bike through technical enduro stages, this crankset delivers the highest stiffness per gram of any option here.

The SRAM GX Eagle Boost Crankset bridges the gap between entry-level NX and premium X01 by using forged 7000-series aluminum arms that offer stiffness approaching carbon at a fraction of the cost. The 165mm arm length is deliberately short to minimize pedal strikes on low-bottom-bracket enduro frames, and the Boost 52mm chainline pairs with 148mm rear hubs to keep the drivetrain quiet and efficient through chunky sections. The direct mount X-SYNC 2 ring is fabricated from steel, which extends chainring life considerably compared to aluminum rings.

Owners consistently note that the DUB spindle simplifies bottom bracket selection compared to older GXP standards, and the 28.99mm diameter interface reduces bearing stress by distributing load across a wider surface area. The 165mm length has become a favorite among riders who found 170mm cranks producing frequent pedal strikes on trail features. Shortening the crank also allows a lower saddle position for descending, improving center-of-gravity control without compromising climbing biomechanics.

The crank arms come in a lunar gray finish that hides wear better than polished or black surfaces. A minor caveat is that the Boost version uses a 3mm offset chainring, while the standard GX uses a 6mm offset — Verify your frame’s chainline requirement before ordering to avoid a mismatch that pushes the chainring too close to the chainstay.

The 175mm version of the SRAM GX Eagle Dub Crankset delivers the same forged 7000-series aluminum construction and DUB spindle interface as its shorter counterpart but with the longer leverage arm that many riders prefer for climbing efficiency and power output. The 49mm chainline is designed for standard 135mm and 142mm rear hub spacing, making it the correct choice for non-Boost frames that account for a significant portion of the existing trail bike fleet. The 175mm length provides a 1.6% mechanical advantage over 170mm cranks, translating to slightly lower pedal force requirements on sustained climbs.

Installation feedback from the community highlights the straightforward DUB interface that eliminates the need for spacers on most 68mm and 73mm BSA shells. The steel X-SYNC 2 direct mount ring shows minimal wear even after extended use in sandy conditions, and the chainline noise is noticeably lower than older GXP-based cranksets. Owners who accidentally ordered the 175mm instead of 170mm noted an increase in pedal strikes, so confirming your preferred length before purchase is essential.

The lunar gray finish resists scratching well, and the crank arm profile includes a subtle chamfer on the outer edge that deflects rocks rather than gouging. This crankset is a direct-fit upgrade for riders moving from SRAM SX or NX who want better stiffness without spending for XO-level parts. Pair it with a DUB bottom bracket specific to your shell standard, and torque the 54Nm crank bolt to spec for reliable retention.

This 165mm SRAM GX Eagle Dub Crankset is essentially the same forged 7000-series aluminum core as the Boost version but configured with a standard 49mm chainline for use on non-Boost frames. It is an ideal upgrade path for riders with 135mm or 142mm rear hub spacing who want the clearance and biomechanical advantages of shorter cranks without switching to a Boost-compatible frame. The DUB interface accepts a wide array of bottom bracket shells, including BSA, BB30, PF30, and BB92, depending on the specific DUB BB purchased separately.

Users report that the 165mm length eliminates pedal strikes on rock gardens where 175mm cranks would regularly catch, and the shorter stroke reduces knee strain for riders with shorter inseams or a history of patellar issues. The direct mount X-SYNC 2 chainring is a steel unit that maintains consistent tooth engagement even after prolonged use in gritty conditions. The arm finish is a subtle lunar gray with a matte texture that does not show smudges or small scratches easily.

One point to note: the standard non-Boost GX crankset comes with a 6mm offset chainring, which pushes the chainring slightly outward. If your frame has tight chainstay clearance, measure the gap between the current ring and stay before ordering. Some riders found that switching to a 3mm offset ring cleaned up the chainline on frames with Boost spacing adapted to 142mm hubs.

The SRAM GX Eagle Dub Boost Groupset is not merely a crankset — it is a complete 1×12 drivetrain that includes the DUB crankset, rear derailleur, trigger shifter, cassette, and chain in one package. The crankset itself shares the same forged 7000-series aluminum construction and Boost 52mm chainline as the standalone GX Boost crank, but the 10-52T cassette provides a 520% gear range that can handle steep alpine climbs without a front derailleur. The X-SYNC 2 chainring on the crank is a 32T steel unit that pairs with the wide-range cassette for balanced gearing across most trail profiles.

Conversion builds — upgrading from older 2×9 or 2×10 systems — benefit from the groupset’s matched components that guarantee shift indexing compatibility out of the box. The GX derailleur features updated cage architecture that maintains chain wrap on 52T cogs, and the trigger shifter uses a single lever push for downshifts with a short, positive throw. Owners who converted their bikes report that the groupset shifted flawlessly under pedaling load and never dropped a chain even through repeated square-edge hits.

Installation requires compatible wheel-hub driver body (XD driver is needed for the 10-52T cassette), and the GX crankset demands a DUB bottom bracket specific to your frame shell. The entire package saves money compared to buying crankset, derailleur, shifter, cassette, and chain individually, making it the most cost-effective path to a full Eagle drivetrain upgrade. Note that shift cable housing is not included; you will need Jagwire or similar housing to complete the install.

The SRAM NX Eagle 165mm Dub Crankset is the most budget-conscious way to get DUB spindle technology and a 12-speed direct mount chainring on your mountain bike. The arms are forged from 6000-series aluminum, which adds roughly 150 grams compared to the GX’s 7000-series construction but preserves the same 28.99mm DUB interface and 49mm chainline. The 165mm length provides the same ground clearance advantages as pricier short cranks, making it a popular choice for riders who want to test shorter crank arms without committing to a higher-tier component.

The included chainring is a 32T steel X-SYNC 2 unit that offers the same wear resistance and mud-shedding tooth profile as the GX ring — the difference is purely in the arm material and bearing preload adjuster, which uses a simpler plastic ring instead of the machined aluminum one on GX. Riders report that the NX crank works reliably with SRAM’s full 12-speed Eagle drivetrain and that the DUB interface reduces creaking compared to older square-taper or GXP systems.

Be aware that the NX crankset does not include the DUB bottom bracket — factor that into your total upgrade cost. The 6000-series arms are slightly more prone to surface scratching than the 7000-series alloy, but the structural integrity under normal trail riding remains adequate. This is a solid entry point for transitioning from a 3x or 2x setup to a modern 1×12 Eagle drivetrain.

The 175mm variant of the SRAM NX Eagle Dub Crankset shares the same 6000-series forged aluminum arms and steel X-SYNC 2 chainring as the 165mm version, but extends the crank length to 175mm for riders who want maximum torque leverage on sustained climbs. The 49mm chainline matches standard 135mm and 142mm rear hub spacing, and the DUB interface ensures compatibility with the same broad range of bottom bracket shells as the higher-tier SRAM cranks. The 175mm length provides a measurable mechanical advantage over 170mm cranks, which riders who prioritize climbing torque over descending clearance will appreciate.

Customer reports confirm that the crankset installs smoothly on BSA73 and PF30 frames with the appropriate DUB bottom bracket, and the steel chainring holds up well against rock strikes that would gouge aluminum rings. The arms are finished in black anodizing that resists corrosion, though the 6000-series alloy does show crease marks under high torque loads more readily than the 7000-series material used in the GX line. For riders on a strict budget who need 175mm arms to match their preferred pedaling mechanics, this is the most cost-effective option in the list.

Keep in mind that the 175mm length increases pedal strike frequency on bikes with low bottom bracket heights, particularly when cornering through uneven terrain. If your frame already has a sub-330mm bottom bracket drop, consider the 165mm NX or stepping up to a shorter GX crank instead. The NX does not include the bottom bracket cups, so calculate that cost before purchasing.

The BUCKLOS Crankset uses forged 7075 aluminum for both the crank arms and the chainring, which is a higher alloy grade than the 6000-series found on entry-level SRAM components. The 170mm arms are designed around a 29mm spindle that mimics the DUB diameter, making it compatible with a wide range of bottom brackets including BSA, PF30, BB30, and BB92 when paired with the correct adapter. The wide-narrow tooth profile on the 32T ring is designed to maximize chain retention across 8, 9, 10, and 11-speed drivetrains, though it is not optimized specifically for SRAM Eagle 12-speed chains.

Users report that the crankset offers a smooth power transfer feel once the spindle bolt is properly torqued, though a consistent note across reviews is that the spindle bolts have a tendency to loosen during the first few rides. Applying blue Loctite to the spindle bolt and re-torquing after the break-in period resolves this issue reliably. The 7075 alloy arms resist flex well under sprint loads, and the titanium-colored anodized finish provides a distinct aesthetic compared to the black-dominated SRAM lineup.

The primary tradeoff is that the bottom bracket included in some configurations has been described as having insufficient grease from the factory, leading to premature bearing roughness. Repacking the bearings with quality grease before installation and applying Loctite to the spindle bolt makes this a reliable budget option for riders converting older frames to a 1x setup. It is not recommended for hard enduro or e-bike applications where torque loads are consistently high.

The CobraCrawler Ultralight Crankset is built entirely from forged 7075-T6 aluminum, including the chainring, and is available in multiple anodized finishes including polished titanium and rainbow. The 29mm spindle length of 130mm is designed to fit the same range of bottom bracket shells as the BUCKLOS — BSA, PF30, BB30, BB89.5, and BB92 — with a DUB-compatible adjustment ring included. The 170mm crank arms are offered alongside 165mm and 175mm options, and the chainring teeth are profiled for 8 through 12-speed chains, making this one of the most speed-agnostic cranksets on the list.

Reviews highlight that the crankset looks premium for the price point, but several consistent quality issues emerge. The chainring is manufactured from a relatively soft batch of 7075, and users report that it bends or deforms after minor rock strikes, causing chain drops that are difficult to correct trailside. The pedal threads on the left crank arm have been reported to have a tight section that makes torquing pedals to spec difficult, and this can interfere with power meter pedal installation. The included bottom bracket has been widely described as having poor bearing smoothness and insufficient longevity.

This crankset is best suited for riders who prioritize aesthetic customization and low upfront cost over long-term durability — think flow trails or pump track use where impacts are minimal. If you choose this option, plan to replace the included bottom bracket immediately with a quality unit from Wheels Manufacturing or Chris King, and regularly inspect the chainring for signs of tooth deformation after every few rides on rocky terrain.
