SRAM Eagle eMTB portfolio grows to 4 groupsets

With the introduction of the NX Eagle drivetrain a few weeks ago, SRAM also released the first 12-speed drivetrain specifically for eMTB’s, and now the Eagle ecosystem has been significantly expanded, as revealed at EUROBIKE.

The SRAM EX1 drivetrain was specially developed for eMTBing, but some riders can’t get along with the big gear steps of the 8-speed cassette. Now SRAM has presented four Eagle groupsets specifically for eMTBs, in future offering as alternatives to the EX1. You’ll be familiar with most of the components already, but SRAM has combined them in ways to add a few new elements.

All eMTB Eagle groupsets rely on the new 11-50T cassette from the NX Eagle groupset. The cassette consists of punched steel sprockets that are riveted together, and it’s available for a fair € 110. The rear derailleur and chain aren’t new either; they’re simply taken over from the existing MTB groupsets.

The shifters, however, are new, because with the new triggers you can only ever shift one gear at a time. This single-click mechanism serves as a safety device, as chains are most vulnerable to breakage during multi-shifts over several gears. The chainrings are also new for eMTBs, which, thanks to the particular Eagle tooth profile promise to keep the chain securely engaged without the need for chain guide – as has already been proven on non-motorised mountain bikes.

There will be four trigger shifters available with the single shift mechanism, XX1, X01, GX and NX
X1 eMTB cranks will be available in lengths from 150 to 175 mm and are compatible with Bosch, Brose, Yamaha and Shimano motors
Eagle chainrings are now available for Bosch with 16 teeth and a 104 mm internal circumference with 30 to 38 teeth
The Eagle chainrings have a unique tooth profile and are also compatible with 11-speed drivetrains
All SRAM Eagle chains are approved for eMTB use. The differences between the chains lie mainly in the surface coating
