SRAM Eagle just got a little better now with extended range! If Eagle just isn't enough for you they've now added 2 teeth to the cassette! If you need a little extra help on the climbs but don't want to sacrifice your top speed by dropping the front ring this is just what you need ...SRAM Eagle just got a little better now with extended range! If Eagle just isn't enough for you they've now added 2 teeth to the cassette! If you need a little extra help on the climbs but don't want to sacrifice your top speed by dropping the front ring this is just what you need! Upgrading your cassette or setting up a 10-52 Eagle drivetrain? You will need a new derailleur since the added range is just a little too much for the 10-52 derailluers. If you've got an AXS derailleur though no need to change your derailleur! If you've still got some life left in your drivetrain, don't worry, that Eagle shifter and chain you have is still good to use for the extended range!
