SRAM XX1 Eagle AXS DUB Groupset - Boost

Spec'd for race day, and hungry for blasting through cross-country laps, SRAM's new XX1 Eagle AXS Boost DUB Groupset hits the market ready to charge to the podium. If you follow the XC race circuits, chances are you've already spotted this beautiful piece of machinery on Schurter's steed, though the tech remained quiet until now, with SRAM's release to the public. The XX1 AXS Eagle groupset offers the lightest weight materials, long-wearing durability, and Eagle's signature 500-percent gear range to land you with the pinnacle of performance, ready to turn your steed into the next generation of superbike.Since SRAM had its electronic expertise dialed with Etap, the first thing we wanted to know was just how much it had in common with its roadie counterpart. Just like on Etap, you'll have a fully wire-free setup, with no need to search for a spot to store your battery -- simply bolt on your shifters, rear derailleur, and pair things together. That's largely where the similarities end. Naturally, the shifters are all new, and because the demands on mountain bikes can be a bit more strenuous, harsh, and jarring, SRAM took a bit of what its designers already have learned about electronic shifting, and made some serious updates to handle the rough and rowdy conditions on the dirt. This includes a two-clutch system (we'll get into this later), and a whole lot more torque. Etap spins at 50,000 RPM, but to get things dialed for the trail SRAM builds the AXS rear derailleur with enough torque to spin 80,000 RPM for booking it down steep and quick descents.Compared to mechanical Eagle groupsets, the Eagle AXS derailleur has been contoured around the frame design a bit more. This translates to increased chain wrap, which improves both load distribution and durability, reducing wear and tear on your chain and cassette for better longevity of components. Dually, this new positioning offers a whole 10-millimeters of increased clearance over mechanical Eagle rear derailleurs. ...
