SRAM Expands Eagle Drivetrain To Include a 10-52t Cassette

Today SRAM expanded the Eagle drivetrains of GX, XO1 and XX1 groupsets to a 10-52t setup, effectively increasing range to a massive 520%.

This means that everyone from weekend warriors to world champions can benefit from the broader gear range to tackle the biggest climbs. For those of you who are happy with the current Eagle range, SRAM says they will continue to offer the 10-50t cassette. Furthermore, the Eagle ecosystem is still intact with mix and match compatibility running through the range from top to bottom.

As part of the Eagle overhaul, the GX groupset gets a totally new finish making it look as good as it performs.

SRAM says that whilst developing the AXS product line they made some architectural adjustments to the derailleur that have provided the foundations for this new expanded range. The changes to the derailleurs include a tweaking of the pulley wheel offset, the cage length and body shape. All AXS derailleurs are compatible with the 52t cassette. Moving forward, all mechanical derailleurs will be optimized for 10-52t and 10-50t ranges. SRAM doesn’t recommend running an early version Eagle derailleur with the 52t as it tends to be less precise and a little labored in shifts. SRAM also released a new ‘master colourway’ with finishes that offer a more customizable experience when building your dream drivetrain. You can now choose from black, rainbow, gold or copper-colored chains and cassettes whilst the cranks and derailleurs are a neutral colour. Lastly, the GX groupset which has become somewhat of a cult favourite gets a totally new finish making it look as good as it performs. Here’s the lowdown from SRAM:
