March 28/16 19:45 pm - SRAM Introduces Eagle 12-Speed Drivetrain

SRAM has announced the first 12-speed drivetrain system, using their new Eagle Technology.  Using the 1x single chainring drivetrain that is the company's hallmark, the new 12-speed system will initially come in two iterations:  XX1 Eagle for cross-country use and the X01 Eagle for Trail/Enduro riding.  SRAM now claims that there is no need for front derailleurs any more.

If you though the previous 10-42 tooth 11-speed cogset was large, then the Eagle system offers a truly massive 10-50 tooth cogset (10, 12, 14, 16, 18, 21, 24, 28, 32, 36, 42, 50) for a 500% range (up from the previous 420% range).

Both systems are completely new, with XX1 offering a new hollow-arm carbon crank (170mm and 175mm options) and CNC-machined chainring (30, 32, 34, 36 and 38 tooth options).  The new rear derailleur has a carbon cage and titanium spring, and is designed for the wide range, as is the carbon trigger shifter.  Interestingly, SRAM is offering a Grip Shift version, their original twist grip shifter.  As you might expect, the chain has been completely redesigned for the system.

The X01 system shares most of the design features of XX1, but is built to be more durable (and thus heavier) for the usage expected in Trail and Enduro riding.  The chainring, cassette and chain are the same in both groups , but the carbon crank forgoes the lightweight hollow core arms.  The rear derailleur and trigger shifter use forged aluminum instead of carbon for extra durability.  The cog and chainring range is identical to XX1.

SRAM says both systems will be available in June, however, they won't be cheap - expect close to $2000 for a full XX1 group and in the $1600 range for X01.
