<\/a>The SRAM RED eTap AXS Disc groupset with Quarq power meter chainring set. A rim brake groupset is also available.<\/span><\/p>\nA new gearing<\/h2>\n
While 12-speed and eTap AXS are both cutting edge developments, it’s the new gear that goes against most against road groupset traditions. Traditionally an 11 tooth sprocket was the smallest on road cassettes but the RED 12-speed cassette goes as small as 10 tooth. This smaller sprocket allowed SRAM to reduce the size of the chainrings compared to standard 11-speed chainrings, while still offering an extended range at both the top and bottom end of the gearing. The reason for shrinking the chainrings, smoother gear progression when shifting.<\/p>\n
<\/a>\n<\/div>\n<\/a>\n<\/div>\n<\/div>\nSmaller chainrings, wider cassettes<\/strong><\/p>\n The 2x RED chainring gearing options now include 50\/37, 48\/35, and 46\/33 which replace the traditional 53\/39, 52\/36 and 50\/34 respectively. The RED single chainring options range from 36 tooth up to 46 tooth, with the aero chainrings topping 48 and 50 tooth. The 12-speed RED cassette is available in three variations, 10-26, 10-28 and 10-33.<\/p>\n Fewer steps<\/strong><\/p>\n SRAM explains that it made an effort to reduce the number of steps in any given gear change. The pay-off is a smoother shifting experience with less fluctuation in cadence when up or downshifting. As mentioned, they reduced the size of the RED chainrings to create smaller jumps but they also paid close attention to creating smaller steps on the RED cassettes. The 10-26 and 10-28 cassettes boast 7 single tooth steps (See the chart below). That said, there is a considerably big 5 tooth jump from 28 to 33 on the widest range cassette offered. Granted that this particular gear is designed as a bailout option for gravel riders on steep slopes.<\/p>\n SRAM RED ETap AXS new mid range gear ratio is a 48-35 chainring and 10-28 cassette combination.<\/span>\n<\/div>\n The chart below compares the RED cassette gear spread compared to traditional 11-speed cassette configurations:<\/p>\n We’re going to have to come to grips with the idea of smaller chainring sizes but the pay off is a wider range and smaller jumps in shifting, which SRAM believes will noticeably improve the experience of changing gears.<\/p>\n The RED eTap AXS rear derailleur employs an all-new chain retention system to reduce the likelihood of the chain becoming dislodged. Instead of the friction clutch system seen on mountain bike derailleurs (and some road derailleurs), SRAM’s new Orbit chain management uses a silicone fluid damper system to reduce chain bounce and derailleur cage movement. The advantage the Orbit system over the friction clutch is that there is no added resistance on the derailleur under slow or light movements, like shifting gears. While the faster, harsher movements associated with chain bounce are resisted. It is good to learn that the Orbit system will require no servicing.<\/p>\n The RED eTap AXS derailleur features a single design with the Orbit system standard across 2x and 1x configurations. This also means that one derailleur design (cage length) is compatible across all gearing combinations.<\/p>\n SRAM RED 42T and 48T aero cranksets.<\/span>\n<\/div>\n Yes, SRAM is doing a 1x specific RED eTAP AXS groupset. As mentioned above, the single chainring sizes range from 36T to 46T (in even-numbered progression, of course). While some riders may employ the single chainring groupset on the road, SRAM is also looking to provide versatility to the ever-expanding needs of cyclists, with those exploring off-road firming in mind.<\/p>\n There is also be an aerodynamic package to accommodate time trialists and triathletes which includes the option of a smaller, more easily integrated eTap BlipBox. The disc-like aerodynamic chainrings are available in larger 50T and 48T sizes.<\/p>\n AXS (pronounced “access” for accessibility) promises integration between SRAM’s bicycle components, smartphones, sensors, and bike computers. AXS provides this broad compatibility of devices by supporting eTAP, Bluetooth, and ANT+. In addition, all AXS enable components will talk to each other.<\/p>\n SRAM’s new AXS wireless system is not defined by riding types. It’s happy to chop and change as the riders see fits. All components with the AXS label will be able to communicate and function with each other. This means that the mountain bike Eagle AXS parts, and even the Reverb AXS dropper post, will work with RED eTap AXS road components.<\/p>\n But there are some mechanical barriers, however. The cassette, rear derailleur, and chain must come from the same groupset. For example, you might want to build a gravel bike with an Eagle AXS derailleur, cassette, and chain using RED eTap shifters on drops. The eTap shifters can then control the Eagle AXS derailleur. You can even throw in a Reverb AXS dropper seat post which can be activated using the eTap shifters.<\/p>\n The AXS App allows for an even deeper level of personalisation through your smartphone. From the app, you can change the behaviour of the components and controls, get maintenance reminders, update the firmware, see battery status. The App is available on both Android and iOS.<\/p>\n<\/a><\/div>\n<\/a>\n<\/div>\n<\/a>\n<\/div>\n<\/a><\/div>\n<\/a><\/p>\nChain management with Orbit fluid clutch<\/h2>\n
