SRAM’s new GX DH drivetrain brings trickle down tech to gravity market
The new GH DX drivetrain brings SRAM’s premiere gravity 1x technology to a price point even park rats can afford (click to enlarge).
If there’s one style of bike where durability and strength trump all other factors, it’s downhilling. These rocketships are designed with one purpose in mind, catapulting you down the mountain as fast as possible, and in the process things sometime break.
One component that’s notoriously vulnerable is the rear derailleur, which is why many downhillers often spend their funds on other components, like better suspension. As a result, they may miss out on some of the amazing DH specific tech that SRAM pioneered with their championship winning X01 DH Drivetrain.
The entire SRAM GX DH drivetrain retails for under $200 (click to enlarge).
Their new SRAM GX DH drivetrain solves that problem by trickling down their proven gravity focused 1x solution to a price point anyone can afford. It consists of a $43 trigger shifter, a $104 rear derailleur, and $30 rear cassette. The grand total? $177.
The $284 machined X01 DH cassette weighs 136g, the $30 PG-720 hits the scales at 224g (click to enlarge).
The new 11-25 seven speed PG-720 cassette is fully compatible with the SRAM X01 DH and splined driver bodies. The jumps are 11-13-15-17-19-22-25. The only downside is that the cogs are all individual pieces, so it’s a little heavy.
The X01 7 speed derailleur retails for $277. Want to save some cash on a replacement if you destroy one during a race run? The new GX DH is significantly more affordable (click to enlarge).
At just a touch over one hundred dollars, the GX DH Derailleur is forty dollars more expensive than the Shimano Zee, BUT is almost $200 cheaper than X01 DH. It has an aluminum cage, uses steel pulley bearings and can accept up to a 28T cassette.
Claimed weight for the GX DH Shifter is 122 grams (click to enlarge).
The final component is the shifter. It’s 3 grams lighter than the X01 version, matchmaker compatible and allows you to click through five gears in one motion.
With these price points, SRAM is making a play at the mid-level OEM market, and we bet a number of new models will ship with this drivetrain.
