Sram X01 Eagle AXS Groupset 1x12s with DUB Boost Crankset 32T

Sram unveiled is first electronic wireless MTB drivetrain ! Main parts of this X01 Eagle AXS DUB Boost 12 speed groupset are without doubt the shifter and rear derailleur because all other components have just some aesthetic changes. X01 rear derailleur design looks like mechanical one but Sram has changed all its construction to integrate battery and engine. It has also a lower profil with a shorter cage for 10 mm more ground clearance and Sram includes new Overload Clutch technology that allows to disengage on impact and return to position faster than you can say it. The easy to install battery, same on all AXS products (Road, MTB, Reverb), takes place on back and has approximately 15-20h of life. AXS shifter is compact a really easy to use, a simple pressure upward and downward on lever with your thumb is enough to shift. But the real advantage of this X01 AXS drivetrain is the very simple installation, especially for those who have internal cable routing...
