SRAM has unveiled an all-new mountain bike drivetrain. Badged GX, the new group is available in 1x and 2x configurations and replaces SRAM’s long-standing X7 and X9 component lines.
Most importantly, GX signifies 1x transmissions taking a big step up in affordability, with the cost of a complete 1x GX group dropping in at £451/ €588/US$564, a massive saving over the cheapest 1x dedicated transmission currently on sale – SRAM’s own X1 group.
Like XX1, X01 and X1, GX in 1x11 and 2x11 configurations features a full 10-42t cassette and uses the X-Sync chain retention technology that SRAM’s mountain bike groups are now renowned for.

The OEM take up of GX1 is an exciting prospect, particularly with SRAM telling us to expect GX on bikes as low as €1,000. To put that into perspective, the cheapest X1-equipped bikes this year are still around the €1,799 mark.
We can also expect manufacturers to mix and match the cross compatible GX1 components with the company's other 1x specific groups, say placing a GX shifter and cassette with an X1 derailleur. Cross compatibility means that current SRAM XX1, X01 and X1 owners will be able to replace broken or worn out parts with these simpler but heavier components if desired.
