Other aspects? The Rival AXS rear derailleur uses a spring clutch that improves chain retention over rough surfaces and keeps the drivetrain quiet and free of chain slap. Perhaps because they coudnt say anything positive about it Thanks again. Also like SRAM, Shimano's shifters communicate wirelessly with the derailleurs. I dont think its a limitation of wireless. Granted, SRAM is a smaller company than Shimano. Published 1 March 23. Yes, I might have to learn a whole new set of gear ratios, but it opens up so much potential for experimenting with gear ranges a road 1x setup with a 10-51 rear block is a real option for those mad enough to try! This refers to the number of times the back wheel rotates for each full turn of the pedals. At the front, Dura-Ace offers the usual 50/34t and 52/36t options. After three years riding the original eTap in its various rim and disc brake guises Ive been very impressed. The shift speed feels very close to existing eTap, but the real plus is just how quietly it carries out those shifts. We found that this makes it easier to ride in a tucked aero position due to better grip. Rather, it means that you can set shift points within the app to make it work better for your style of riding and allow the rear derailleur to drop or gain 1-2 gears when you shift the front. You shift one (usually the right one although that's configurable) to move to higher gears and the other to shift to lower gears. How is that possible on a decade old groupset? Purchased as a standalone upgrade, the power meter spindle is $100 less than a Quarq power meter spider (without chainrings) and $470 less than the integrated power meter and one-piece chainrings used on Red AXS. GRX Groupset total weight does not include cassette and chain. Yes, those crank arms are homely. The lag from the wireless protocol should be imperceptible. SRAM Red chainrings come in 46/33t, 48/35t and 50/37t options as standard, so you can have a lowest ratio below 1:1 if you use a 10-36 cassette with a 46/33t or 48/35t chainset, without losing top end ratios. The Dura-Ace R9200 chainset carries forward the looks of its 11-speed predecessor. The SRAM AXS app is used to configure its electronic groupsets. If I do go down the AXS path this year, I think an Easton crank might be the way to go. A quiet, secure and smooth ride, whatever the terrain. Compatible with all other AXS components. SRAM RED eTAP AXS Hands-on: Everything To Know About The - DC Rainmaker Such is the design of eTap AXS, the clutch isnt needed. Every major publication/website has only talked about AXS since it came out. The only / or last one I can remember that looks decent are the original XX double MTB cranks. To reduce costs, there is a slight weight penalty. Out of Stock. Heres how it works. Front derailleur cable routing wireless. The Orbea Orca, which Ive been running AXS on, is equipped with two blips mounted under the tape on the underside of the bars top, so you can shift gears when riding holding the tops while on a long, steady climb. That type of publicity is infinitely more effective than being the official drive-train sponsor of some random WT team. Think of pushing your open hand through water slowly as opposed to as fast as you can and how the resistance increases.
