SRAM GX Eagle Dub Groupset Black, 170mm, 32T 2019
SRAM GX Eagle Dub Groupset Black, 170mm, 32T
Rear Derailleur: GX Eagle 12-speed
Single-ring drivetrains offer numerous benefits compared to 2x systems encumbered by a front derailleur: quieter operation, less maintenance, simplified shifting, and much better chain retention. Occasionally you might run out of gears on a tough climb or a fast descent, but that changed when SRAM released the Eagle 12-speed group. With a 500% gear range that rivaled 2x drivetrains and some of the best mechanical shifting we've ridden, it's no wonder that Eagle took the market by storm. Cost was high for the initial release of XO1 and XX1, but then SRAM gave us GX Eagle which made 12-speed attainable for the price-conscious rider. This GX Eagle DUB Groupset includes everything you need to put Eagle on your bike, except for an XD driver for your hub and a SRAM DUB bottom bracket. This groupset comes with the crank set, cassette, chain, rear derailleur, shifter, and b-gap adjustment tool. The crankset is light and sturdy, comprised of 7000-series aluminum rather than carbon, helping keep the cost down. It comes with a 6mm offset chainring for non-Boost bikes with QR or 12x142mm rear spacing. The crankset features the DUB spindle, which SRAM claims is stiffer than GXP and lighter than BB30. DUB is compatible with virtually any frame if you get the right DUB bottom bracket (not included). The shifter and derailleur yield comparable performance to the premier XO1 and XX1 options, separated primarily by a difference in weight and the material that comprises the shifter lever. The cassette has the same 10-50t gear range, but with all steel cogs. It's heavier but more durable due to the steel construction. The chain uses solid pins and is chrome-hardened for longevity. It doesn't have the hollow pins or the ti-nitride coating of the premium XX1 chain, but shifting is seamless nonetheless.

The benefits of 1x11 drivetrains were undeniable for riders who made the switch to a single-ring setup. Better chain retention, quieter operation, lower maintenance, and simplified shifting just made sense on the mountain bike side of things. The only downside was running out of gears, being forced to spin up a steep climb at an uncomfortable cadence or wishing you had a little more top end on fast fire roads and descents. When SRAM released the 12-speed Eagle group that all changed. The addition of a 12th gear and the dinner-plate sized cassette that came with it left some skeptical, but it gave us a 500% gear range that rivaled that of 2x systems, and provided some of the best mechanical shifting on the market. It was pricey at first, but then GX Eagle came onto the scene, bringing Eagle to the masses. This GX Eagle DUB Groupset includes everything you need to put Eagle on your trail bike, less a SRAM DUB bottom bracket and an XD driver for your hub. This groupset includes the crankset, cassette, chain, rear derailleur, shifter, and b-gap adjustment tool. The crankset is made of 7000-series aluminum which is both light and strong, and helps keep the price of the groupset reasonable. It comes with a 3mm offset, Boost chainring for bikes with 12 x 148mm rear spacing. The crankset uses a DUB spindle, which SRAM created to be compatible with virtually any frame, provided you get the correct DUB bottom bracket (not included). SRAM claims the DUB spindle is stiffer than GXP, yet lighter than BB30, so combined with the increased compatibility it makes sense that they made the rolling change to DUB. The derailleur and shifter offer similar performance to their higher-end XO1 and XX1 counterparts, the primary difference being weight and the material composition of the shift levers. The cassette provides the same mighty 10-50t gear range, but with all steel cogs. Yes it's heavier, but arguably more durable. The chain uses solid pins instead of the hollow pins found on ...
