SRAM Red eTap AXS 12-speed Wireless electronic shifting Rim brake and disc brake options 10-tooth smallest sprocket requires XDR driver freehub body Orbit Fluid damper rear derailleur Power. Shimano's E-Tube app provides similar lever customisation, but you can also alter the speed of shifts. However, on the road side it lacks any type of damper or clutch. I added the left crank arm weights, and the cassette, its all here now. In Shimano's case these are wired to the levers while SRAM has both wired and wireless options. So what compromises are made to bring down the cost? We and our partners use data for Personalised ads and content, ad and content measurement, audience insights and product development. SRAM says that this ability to absorb water is an advantage if you do get damp in your brakes, as it means that it's less likely there will be free water droplets in the hoses than with an oil-based system, where it would boil at 100C and so potentially impact performance. The wide crank requires a matching wide front derailleur. This narrower grip is possible because Rival eTap AXS doesnt have contact point adjustment for the brakes, and also does not allow for blips (auxiliary remote shift buttons). Will that luster hold up? To be fair, I think the Eagle chainring tooth profile is a mind-blowing innovation that is as well executed as Shimanos best product. 2023 SRAM Force AXS & XPLR groups updated with lighter, better tech. It's more comfortable than a smaller lever as hand pressure is distributed over a larger area but might be less easy to grip for smaller hands. What is the point of weiging just right crank arm? SRAM has a great marketing team and some good innovations but I dont think they respect the end user as much. Who has the answer? Compatible with all other AXS components. Wouldnt besurprised if were waiting a while, they probably need to make some money back on axs. So I wanted to take a minute to process all that before writing my first ride impressions of the new groups. SRAM Red chainrings are machines from one piece of material so are lighter and stronger than before. But with a Force AXS group coming in April, that would be good timing. Granted, SRAM is a smaller company than Shimano. A Force eTap AXS group with a similar set-up weighs 2,600 grams, a difference of 183 grams. The days of riders pushing huge gears with a tiny rear block are well and truly over, as ideas and beliefs over physiological efficiency change. The difference to Red eTap AXS is 541 grams. Allow Necessary Cookies & Continue This directly impacts the stiffness of the chainrings, which itself has a big bearing on how well the front mech will shift as well as other performance benefits for the racers. Highlights. Add custom gearing Learn more about bike gearing Estimated Spec Level He has been writing about the latest bikes, components, and cycling technology for 14 years. It can absorb water from the atmosphere, but even with 4% water still boils at 155C. There are more teams riding Campy than Sram. I dont think its a limitation of wireless. Basically, when you change gear at either the front or the back, the auto shift moves the other derailleur if necessary to ensure you are always shifting to the next available gear (in either direction) to keep changes as smooth as possible. Short for 10-26 up to 10-33T / Medium for 10-28 up to 10-36T Weight without battery 36T Version Rear derailleur max. Thats something you could have noted. In its place is a design that has both chainrings machined out of one block of material that mounts directly to the crank arms on a spline, which is a design mountain bikers have had for a few years now. Warren Rossiter is BikeRadar and Cycling Plus magazines senior technical editor for road and gravel. Not so much. Some of our partners may process your data as a part of their legitimate business interest without asking for consent. We were lucky enough to get our hands on Orbeas Orca a few months ago in the new eTap AXS spec and its this bike Ive used for my testing. For example, in the eTap AXS, the largest ring on what is effectively the double chainset has 50-teeth and the smallest sprocket is 10-teeth, which means the ratio is 5:1and the wheel will turn five times for every pedal revolution. The weight differences come down to materials and construction. Campagnolos answer was to add a 12th sprocket to fill the gap in the centre of the block, which works to an extent but doesnt entirely solve the problem. Some of their mountain drivetrains are so sensitive to cable tension its annoying as hell. Heres how it works. Everything from the overall AXS system that would control future wireless components from SRAM, Rockshox and more, to the actual new RED eTap AXS road group and its Eagle mountain bike counterpart. Always a strong suit of SRAM, the braking is better than ever, looking and feeling like something dedicated for the road and not something cobbled from a mountain bike parts bin. Then again, might it just live up to the hype? That makes them more agile but less capable. So, the short answer is, it didnt feel any faster, but I liked the speed of the original eTap (and this new one) just fine. Rival uses aluminum brake levers and crank arms, while Force uses composite brake levers and solid carbon crank arms. Heres a full list of everything you can buy as of February 2019, and theres plenty more coming. Their mechanical 22 systems are flawless. Theres a limit as to how fast you can move the chain from one cog to the next and still have it engage the teeth properly, and the multi-shift (holding down the shifter to run up or down multiple cogs at a time) is already pushing that limit. It is more important for R&D than for marketing. Shimano R9200 brakes use Servo Wave tech, again ported from its MTB range, that gives you progressive brake action that is more aggressive at the end of the stroke and lighter when you're just feathering the brakes. Do they work? If there were something I didnt like about the group, Id say so, but it really is that good based on first impressions. It also offers a 50% discount to the original owner when they buy a replacement power meter/chainring set within five years. Ive ridden Red etap and the delay in shifting was quite annoying considering this is supposed to be a top tier group its pretty lame that it shifted slower than 105. Youre welcome.

The problem in reducing size is that you also reduce strength, so SRAM both flattened the top and made it out of a new material that is both harder and longer wearing than its old model. SRAM Red eTap AXS brake/shift levers have a large single paddle each. A remote mount for the battery would give even more clearance at the front derailleur. Then they trickled down to the X9, X7 and X5 dual chainring cranksets. 2021 Road & Gravel Groupset Weight Comparison Updated Apr-2021 (added Rival AXS 12-speed) Crankset weights will vary depending on size and length. Shimano Dura-Ace brakes come paired with XTR MTB brake rotors, Shimano's E-Tube app can be used to fine tune shifting. Other aspects? The larger clearance to the middle of the bottom bracket also benefits very wide tires. Force uses 11-26 cassette. A whole new concept? . Launched in 2015, RED eTap was SRAMs first foray into electronic groupsets. Direct-mount chainrings are available in 38t through 46t in two-tooth increments.Read more about the difference between 2x and 1x drivetrains on gravel bikes. Rival AXS rear derailleurs use a more traditional mechanical clutch. Three teams are on Campy, two are on Sram. The action is smoother, quieter and arguably quicker than the first generation, and its adaptability, in that you can run it 2x, 1x, or combine it with any of the new AXS mountain bike gearing launching soon, is impressive, making this an electronic groupset you could run on the road, gravel, cross, mountain and downhill. Gear steps: 12. If breaking batteries becomes an issue for me, thats where Im going. This is the increased weight of using the hydraulic calipers and hydraulic shifters. Gear ratio range: 280 - 330%. Dura ace is much cheaper. They must be able to deliver the tech at an attainable price point so that the masses can taste the experience. More specifically, the batterys placement, which is now a couple millimeters further outboard. It's set to cost. Now, you should be able to easily clear a 70045 (frame/rim/tire dependent, of course), which is about as big as most of us are likely to run on a 2x setup. Who knows, thats why we have a long term review bike/group to test. I am eager to hear more of your feedback. SRAM RED eTap AXS 12-speed and wireless, it's the ultimate in modern shifting Specifications Shifting: Wireless Braking: Disc, dual pivot rim Speeds: 1x12, 2x12 Weight: 2101g 2x rim /. Expect a full test of this new Orca soon, but Ill just say its a bike thats every bit as impressive as the gearing its running. SRAM Rival eTap AXS is a more affordable wireless electronic drivetrain. You can choose to shift at the front should you want to, like when youre coasting up to traffic stops. First of all, lets talk about that 12th sprocket. They are compatible with 135mm, 142mm, and 148mm Boost rear axle spacing. The Flattop design allows for a narrower chain without compromising strength or durability. Are 13-tooth gear jumps considered cutting edge technology now? Gravel and adventure riders might prefer the Rival 43/30t wide crankset, with its lower gearing and wider stance (150.5mm q-factor vs. 145.5mm) to match gravel bike chainlines and clear tires up to 700x45c or 27.5x2.1. To reduce costs, there is a slight weight penalty. SRAM now gives you the 50/37t chainrings previously reserved for Red, but the test bike was specced with smaller 48/35t rings - SRAM's version of the mid-compact chainset. However, Shimano still attaches the chainrings using bolts, although we've certainly never noticed any amount of flex. Once you've paired all the connecting parts to the apps over Bluetooth you can then choose to make either groupset work in two different ways. Shimano's is also the cheaper groupset albeit only marginally, saving you around 90 at full retail price. The intuitive simplicity of SRAM RED eTap with an added performance of hydraulic road disc brakes (HRD). SO many people ride and love to ride the 1st gen etap. This is called compensating shifting by SRAM and semi-synchronised shifting by Shimano. Such is the design of eTap AXS, the clutch isnt needed. Note: SRAM eTap component weights includes batteries because batteries all weigh the same. Learn how your comment data is processed. England and Wales company registration number 2008885. The 48/35 and an 11-28 is the equivalent of a 52/36 with an 11-28 cassette. That doesnt mean they cant be easily anticipated or quickly deduced. We captured slo-motion film(watch the road video at that link)of the derailleur working its magic, showing off how it managed the chain even over terrain so rough it had the bike skipping off the ground. It's geared to flat time trials as well as gravel, with larger rings designed to be aero. Bikerumor Copyright 2013 2023. SRAM Red eTAP Groupset Weights Notes on SRAM Groupset Components All weights are taken from SRAM. We've removed bottom bracketweight as these are frame dependant. Since then, hes reviewed hundreds of bikes and thousands of other pieces of cycling equipment for the magazine and the Cycling Weekly website. And, hes totally gone down the NFT rabbit hole. Small gains in aerodynamics here or weight loss from a bikes chassis there are often breathlessly described as game-changing, when in fact theyre merely reasonable, expected gains brought about through refinement by clever sorts. FWIW, Ive asked several times when the mechanical 12-speed groups are coming and only getting radio silence, so Im guessing they simply dont want to spoil the surprise. Works like a charm and IMHO shifts better now than it did with the force chainring. You'll save yourself around 100g by opting for Dura-Ace over Red eTap, although the latest 12-speed Dura-Ace is actually a few grams heavier than the older 11-speed version; it looks as if the quest for ever-lower groupset weights may have peaked. The brake/shift levers are bloody awful too. SRAM for innovation, Shimano for execution. the gap between the next sprocket up and next sprocket down is bigger. SRAMs RED eTap AXS will also be available on a whole host of 2019 bikes with brands such as Specialized, Trek, Canyon, Orbea, BMC, Giant, Liv, Scott, Cannondale, Cervelo, 3T, Open, Rose, Parlee and Koga all confirmed. Thats all they had available at the launch, but Ive pulled the left arm and cassette off our demo bike and added those weights to the post. One thing that isnt mentioned here is that the powermeter is built into the rings, thus once you wear the rings out, you have to buy a new powermeter. The problem with this, however, is that the bigger range of gears in an 11-speed cassette mean bigger jumps for the chain, which puts the system under stress, with less predictable chain jumps. Let's take a look: Derailleur weight is the only functional difference in SRAM's AXS line. Sign up to receive Bikerumor content direct to your inbox. In contrast, Shimano has stuck to cassettes that start with an 11-tooth smallest sprocket, as it claims that this is less prone to wear as a greater number of teeth are in contact with the chain. In his time as a cycling journalist, Warren has written for Mountain Biking UK, What Mountain Bike, Urban Cyclist, Procycling, Cyclingnews, Total Bike, Total Mountain Bike and T3. SRAM calls this sequential shifting, Shimano synchronised shifting. Rival AXS derailleurs feature the same shifting precision and reliability as their Force and Red AXS siblings. AXS has real innovations that should be lauded. The group offers 33/46 and 35/48 chainrings but not the 37/50 option. Shifting is actuated by switches on the brake levers, which send a signal to the derailleurs to do their thing. How often do people wear out the big ring and small ring at the exact same rate? That Trek Checkpoint is now in our offices for long term review, too, so Ill report on long-term durability and function after many, many more miles. As mentioned above, both SRAM and Shimano offer either rim or disc brake options. So, I do think SRAM is onto something here, and I wouldnt be at all surprised to see other chainring manufacturers following suit. Some folks like to find some little nitpick or make something up just so they sound critical, but not us. SRAM RED eTap AXS Actual Weights Road 2x (48/35 combo) - 419g with powermeter Road 1x (48t X-Sync) - 395g with powermeter Left crank - 156g Front derailleur - 165g with battery Rear derailleur - 247g with battery 10-33 Cassette - 211g Shifters - 233g/234g with coin cell batteries installed Updated Blip Box - 24g I agree, the mechanical group will really help usher in their new gearing concept to the masses. As traditional freehub bodies are too big to allow anything smaller than an 11, SRAM chose to use a variation on the aforementioned XD Driver it pioneered on its 1x mountain bikes (and which has already been seen on 1x groups on road, cyclocross and gravel bikes). You can add me to the 12s mechanical waiting list. Hiding under the hood, though, are a big collection of incremental running changes that have been added to both Red and Force groups over the years and finally getting codified here. To pair with the Rival AXS 12-speed chainrings and cassettes, there is a matching Rival AXS Flattop chain. This design allows any chainset in the range to be easily upgraded to use a power meter from sister brand Quarq. The other really interesting part of the new AXS group is the sequential and compensating shifting options. And apparently the same capability but at ultegra price or less. Were a year on and availability is still sketchy, and theyve had to go back to the drawing board one hubs and cranks, after releasing them a year ago. Over the years, Warren has written about thousands of bikes and tested more than 2,500 from budget road bikes to five-figure superbikes. For the road test, I was handed a Trek Checkpoint gravel bike equipped with the new eTap AXS parts, Zipp 303 tubeless ready wheels and the bike brands sweet vibration damping tech. It's worth noting though that this means that once a chainring is worn you need to replace both. Id only add that if EVERY media outlet is reporting nothing but positives, Id say its a pretty good indication of the groups merits. Rumor is the Force version will have a removable PM. Theres also an all-new motor with more power and faster signal transfer, to go along with the groupsets overhauled chipset thats running things. I keep waiting for the moment when their reach no longer exceeds their grasp. This set-up has greater capacity than SRAM's and Shimano claims a range of 1000km between charges. Sure, its all clean and new, but still, it was noticeable. GRX Groupset total weight does not include cassette and chain. Whether you agree with me or not, you missed out on addressing my concerns with your review. As with all products in the AXS ecosystem, the AXS app allows riders to adjust shifting modes, personalize their controls, and gain insight into how they use their drivetrains. Red cassettes are machined out of a single block of steel to minimize weight. A lot to process. There is something to be said for just being the best out there and sometimes that requires breaking changes that screw up compatibility. The Durable Unifying bottom bracket (DUB) is SRAMs answer to creaky press-fit bottom brackets. Today SRAM announces their latest RED groupset lineup, SRAM RED eTAP AXS for road and off-road. Yes, those crank arms are homely. The XD driver had been adapted for the road, wth the XDR driver, which is ever so slightly wider than its off-road equivelant, allowing for a smaller 10-tooth sprocket, which opens up a whole new set of numbers to achieve even bigger gear ranges. Doing so without affecting its strength is a challenge, which led SRAM to rethinking its chain design. In reading each review of VXS, I have waited and waited for any kind of comment on shift speed. Both the SRAM AXS and the Shimano E-Tube smartphone apps allow complete customisation of your shifting. SRAM Eagle AXS MTB First Impressions, https://www.sram.com/stories/19-road-team-roster. In comparison, Shimano's crankset is created using the brand's Hollowtech II technology. 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. Cassettes are 11-28 (or closest) We've removed bottom bracket weight as these are frame dependant. With 48/35t chainrings, 175mm cranks, a 10-30t cassette, and hydraulic disc brake calipers, the claimed weight of a complete Rival eTap AXS group is 2,783 grams. And it's still wireless. Lever shape is largely unchanged from the original eTap. Crankset weights will vary depending on size and length. The AXS technology allows you to make your shifters do what you want them to, and the brake levers have a customizable reach. Rival AXS shifters pair with any other component in the AXS line-up, including Eagle AXS rear derailleurs, for riders interested in a wide-range mullet set-up a 10-50T cassette with a single chainring. I hope that puts it into perspective. Since top end mountain bikes have been 12-speed for several years, the XTR chain has been proven to be robust. There's an indicator light on the rear mech that indicates charge level and, like SRAM, you can also check battery status in the Shimano E-Tube app. Strangely none of the reviewers thought it relevant. You can also buy a separate power meter spider as an upgrade to a non-power meter chainset. While there were pavement and gravel riding opportunities, gravel was the right choice to drive home some of the key new features of the group. The levers offer two ports per side for SRAMs accessory blips, which allow you to change gear anywhere you like on the handlebars. And its nice to have options. Sponsoring teams IS marketing. Di2 is faster and better in my opinion and from a performance standpoint, that matters. Warren Rossiter (BikeRadar) has been using it about 2 months, and says in his video on it that its maybe a wee bit faster. And what about XTR 112? Here they are. Which leads me to the last big change: Gearing. Front shifts are more positive and completely accurate, even when shifting over broken surfaces as the rear mechs damper increases the chain tension and prevents any chatter and bounce. SRAM unleashed a whole new concept of gearing and gear ratios as part of the new group, and it will almost certainly inform future products as well. 33T: 33T=5mm / 30T=10mm / 28T=10mm / 26T=14mm (chain in largest sprocket) Rear derailleur max. Agreed. Ive come to expect great ideas with mediocre execution from SRAM. A complete group. It's not a lightweight choice, but it compares extremely well with. It's worth noting though that Shimano's rear mechs also come packed full of tech, including the brand's Shadow design which is borrowed from its mountain bike groupsets. There's an 11-28t cassette in the works but still not available commercially. The rear mech will work with either a 1x or 2x system and to get around the need for a clutch on a 1x system, used to retain chain tension on rough terrain, SRAMs come up with a clever alternative, called Orbit. This slims down the derailleur but also keeps it pulled up and out of harm's way when riding. There are two mens world teams on SRAM, Trek Factory and Katusha The first ten sprockets are machined together, as are the largest two. A new $249 spindle-based Quarq power meter. Hes been cycling for a lot longer than that though and his travels by bike have taken him all around Europe and to California. One thing we did notice in our testing was that the SRAM groupset was significantly more silent than its Shimano Dura-Ace rival. If it's good enough for the likes of Peter Sagan and Mark Cavendish it's good enough for us. All rights reserved. Then theyll be cooking with gas. The Rival rear derailleur, for example, has steel bearings, steel hardware, and an aluminum pulley cage. Future Publishing Limited Quay House, The Ambury, Every review of axs so far is pure fluff. The Orbit Fluid Damper provides chain retention using fluid resistance. Using this, the brand is able to create a hollow crank arm while maintaining stiffness and decreasing weight. I am running SRAM force cranks and the red chainring. The harsher the bump, the more resistance it applies to keep the chain under control. The spindle-based unit measures left side power and doubles it to calculate total watts.
