Today SRAM unveils a massive new eTap AXS road gearing system with incredible range and a sub-1:1 ratio. Big paved and gravel climbs have met their match.
SRAM’s eTap AXS has been a resounding success. The brand’s top-of-the-line RED groupset has gracefully moved the American-born-and-bred company to the tip of the spear for high-end road and gravel bike components.
And with the new upgrades, SRAM Force eTap AXS offers the same wireless, programmable shifting at a more affordable price point. Here’s everything you need to know.
SRAM RED eTap AXS: 36T Max Rear Derailleur
The current RED eTap AXS rear derailleur will clear a 33-tooth cassette. The new addition announced today will clear a whopping 36-tooth cassette, made possible by a length change in the derailleur’s body near the B-bolt.
This massive chain-management capacity expands the gearing range of both double- and single-chainring setups.
With this new derailleur’s added capacity and its compatibility with 46/33 chainrings and 10-36T cassette, a 502% gear range is now a reality, with a low, sub-1:1 gear ratio of 0.92. A 48/53T chainrings render a 494% gear range and a low ratio of 0.97.
These new gearing range potentials add pedaling force and cadence options to improve both road and gravel performance — and enjoyment.
SRAM RED eTap AXS: Other Features
The new RED eTap AXS 36T Max rear derailleur maintains the incredible Orbit chain-management system. I’m always amazed by the silicone fluid-damped system’s ability to control the chain slack on my gravel bike when bombing the dirt roads in my area.
Even square-edged potholes can’t induce chain slap against my chainstay. So I don’t even bother with a protector anymore. The large X-SYNC pulleys and ceramic bearings of the current RED derailleur carry over, as well as the eTap battery.
