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. Force uses 11-26 cassette. SRAM's hoods are quite large. Rumor is the Force version will have a removable PM. It developed a new type of freehub body the XD Driver for the dirt, which introduced 12-speed gearing to its flagship Eagle groupset, and has cleared the path for use on the road too. 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. Or not being able to use your wheels without swapping out parts on them? 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. So I wanted to take a minute to process all that before writing my first ride impressions of the new groups.

Plus, it applied a hard wearing shiny finish for good measure. Also note that since as standard the power meter is integrated into the chainrings, which SRAM says it's done to ensure the best accuracy, you need to replace this too when you replace the rings. The Durable Unifying bottom bracket (DUB) is SRAMs answer to creaky press-fit bottom brackets. With SRAM ostensibly leading the way with their fully wireless 12 speed eTap AXS groupsets, Shimano made steps in the same direction with the release of semi-wireless models in 2021.. Rival AXS derailleurs feature the same shifting precision and reliability as their Force and Red AXS siblings. SRAM seems to be kicking Shimanos butt across the board- mountain and now road. There's also the option to have a wired connection between the shifters and the derailleurs. SRAM Gravel SRAM XPLR Also like SRAM, Shimano's shifters communicate wirelessly with the derailleurs. The optional power meter by Quarq is solid and the numbers its providing match those I get from the Quarq meter I run on my own bike. Meaning, you no longer have to make front shifts, you simply press one side to go easier and the other side to go harder, then it shifts front and/or rear for you to run through the gears in the most appropriate sequence. The Rival AXS front derailleur is optimized for X-Range chainrings and uses Yaw technology, so theres no need for trim to compensate for extreme gear combinations. An example of data being processed may be a unique identifier stored in a cookie. This refers to the number of times the back wheel rotates for each full turn of the pedals. You can also run a 10-36 cassette with a specific, compatible wider-range Red derailleur. That type of publicity is infinitely more effective than being the official drive-train sponsor of some random WT team. There are no wires to route through the frame, which simplifies setup. A whole new concept? Would you question the quality of something if EVERY one of your friends was using it and lauded it? Ive ridden the AXS and the shifting IS slow compared to di2 but fine if you like etap. We review Rival AXS's weight, pricing, and how it compares to Force AXS and Red AXS groups. The less pronounced jumps between gears make the best use of your efforts and create a more controlled cadence, as the seven 1-tooth jumps are between the gears you will use the most is better than anything currently available (bar a custom time-trial straight through cassette) and thats the Holy Grail for smoother pedaling. SRAM Red derailleurs each have their own removeable battery attached to the rear of the mechanism. 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. I dont know why this is relevant besides determining where brands want to put their marketing budget. Complete Rival power meter cranksets comes in standard and Wide versions. It can absorb water from the atmosphere, but even with 4% water still boils at 155C. Gear percentages, as seen in the above chart, refer to the gear range of the cassette, or the difference between highest and lowest available gears. Note:Di2 weights do not include wiring/junction box/battery. They are compatible with 135mm, 142mm, and 148mm Boost rear axle spacing. Gear steps: 12. The two most obvious material differences arefound in the brake levers and crank arms. Small vision with great execution. A lot to process. Add contacts to an eTap battery block, pogo pins to an eTap battery cover, wire them together, and secure the battery under your bottle cage or somewhere. Battery-to-tire clearance was a known issue with the 1st gen eTap group when running anything larger than a 70040 tire. So, I do think SRAM is onto something here, and I wouldnt be at all surprised to see other chainring manufacturers following suit. SRAM revolutionised groupsets four years ago with its wireless eTap system. Launched in 2015, RED eTap was SRAMs first foray into electronic groupsets. Theyre all going to select a similar number of riders for product testing. Prices . The derailleur also comes with faster pulleys, bearings, motors and signals, improving speed in every way. At the front, Dura-Ace offers the usual 50/34t and 52/36t options. To be fair, I think the Eagle chainring tooth profile is a mind-blowing innovation that is as well executed as Shimanos best product. 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. The rest of it looks great but I find the cranks really unattractive. https://www.sram.com/stories/19-road-team-roster. While it looks super shiny, its the shape that sees the biggest change the plates are not only thinner, but a different shape, with the chains links having a flat top edge. How is that possible on a decade old groupset? Fresh graphics with subtle-yet-shiny paint catch the eye, and the one-piece chainrings and slimmer brake hoods. Shimano 12-speed cassettes are backward compatible with its 11-speed freehubs. Note: Mechanical weights do not include cabling. 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. The material its used is both harder and stronger, and finished in what its calling Hard Chrome. While the electronics and all that have been improved to be faster, my experience was that the shifting itself felt the same as prior eTap. The Dura-Ace R9200 chainset carries forward the looks of its 11-speed predecessor. 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. SRAM Red eTap AXS brake/shift levers have a large single paddle each. You will find snaps of Warrens daily rides on the Instagram account of our sister publication, Cycling Plus (@cyclingplus). Rotor UNO Hydraulic Groupset The principle behind the damper is that the faster it moves, the more the resistance builds. Shimano gives you more flexibility with how this is configured, although this does increase the chances of getting a configuration that doesn't work well. Some of their mountain drivetrains are so sensitive to cable tension its annoying as hell. The roads we used were mostly dirt, looping in and out of Saguaro National Parks western district (check out our Where To Ride guide for more on this sweet winter training area!). The shift speed feels very close to existing eTap, but the real plus is just how quietly it carries out those shifts. I dont mind it until Im at race wattage and then its a first world problem because the shifting is noticeably slower than di2 of any gen. Ive got 7970 still and it shifts faster than AXS. Agreed. Already have an account with us? SRAM Red chainrings are machines from one piece of material so are lighter and stronger than before. A system that does exactly what you want, when you want. Cycling Weekly is part of Future plc, an international media group and leading digital publisher. Why cant shimano be wireless yet? Most of their parts in general are aesthetically acceptable, with the exception of their crank arms. Beyond these changes, little things like improved texture on the shift paddles and visual refinements add up to a group that offers a drastically improved experience. You could have mentioned something to that affect. With the latest R9200 version of Dura-Ace released in 2021 there are more similarities between the two road bike groupsets than there were, but plenty of differences still. SRAMs break with traditional gear ratios has meant some radical design changes chainset included. The integrated PM is so wack in my opinion. Both brands' disc brakes are designed to work with either 140mm or 160mm rotors. These are then pinned together to create the 12-speed block. Strangely none of the reviewers thought it relevant. SRAM Red eTap AXS and Shimano Dura-Ace are both now 12-speed and electronic only and both have wireless comms between the shifters and the derailleurs. How has SRAM done it? Rival uses aluminum brake levers and crank arms, while Force uses composite brake levers and solid carbon crank arms. 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. 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. You can assign the groupset to work in one of two semi-automated ways. 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. 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. To reduce costs, there is a slight weight penalty. BA1 1UA. Other aspects? As mentioned above, both SRAM and Shimano offer either rim or disc brake options. SRAM took a new approach to road bike gearing with Red eTap AXS. To work out the range of a cassette divide the largest sprocket by the smallest and multiply by 100, and looking at the range of AXS the ranges are broader than traditional gearing. Red cassettes are machined out of a single block of steel to minimize weight. Works like a charm and IMHO shifts better now than it did with the force chainring. Hit both together and you'll initiate a front shift. You can also buy a power meter upgrade kit (but not a complete groupset) with 52/39t, 54/41t and 56/43t rings. Shimano is rolling out special editions for gravel and road. However, Shimano still attaches the chainrings using bolts, although we've certainly never noticed any amount of flex. Note that the former gives you a 1:1 lowest ratio when paired to the wider range 11-34t cassette, matching SRAM's lowest range configuration. The harsher the bump, the more resistance it applies to keep the chain under control. Last year, Merida revitalized its line up of trail and enduro bikes with the launch of the 2023 Merida ONE-SIXTY and ONE-FORTY, the former of. Cycling Expert; . For the crank weight, where is the spindle and left crank arm? Honestly I would not, because the existing system is still so good. In the case of eTap XRS, the sprockets make up two blocks pinned together to produce the whole, but on many designs sprockets can be individual, particularly as they get smaller. The levers havent really changed in shape, but the finish looks impressive with carbon levers finished with chrome graphics and a new softer and textured grip that feels good and offers a solid connection even in heavy rain wearing winter gloves. The higher boiling point should make a DOT fluid-based system more stable, says SRAM, leading to longer periods between brake system bleeds. Graduations: 10-28 or 10-33 teeth. Shop now RED ETAP AXS HRD SHIFT-BRAKE SYSTEM Whereas SRAM brakes use DOT fluid, Shimano's use mineral oil. It uses a nickel-chrome plated cassette with full pin construction for durability and light weight. This set-up has greater capacity than SRAM's and Shimano claims a range of 1000km between charges. Once the rear mech reaches a pre-defined point on the cassette the next shift will initiate a front mech shift with the rear mech making a corresponding shift in the opposite direction to give you the next gear ratio up or down the cassette. Since then, hes reviewed hundreds of bikes and thousands of other pieces of cycling equipment for the magazine and the Cycling Weekly website. SRAM's hoods house the hydraulic brake reservoirs as well as the shifter electronics. SRAM's eTap AXS components, in contrast, are wireless. Every review of axs so far is pure fluff. This is something most of us do manually anyway, but now SRAM will do it for you. He has been writing about the latest bikes, components, and cycling technology for 14 years.

The levers offer two ports per side for SRAMs accessory blips, which allow you to change gear anywhere you like on the handlebars. Warren Rossiter (BikeRadar) has been using it about 2 months, and says in his video on it that its maybe a wee bit faster. Their mechanical 22 systems are flawless. Everything is geared around the 10-tooth sprocket on the cassette, and this has allowed the brand to shrink the front chainrings, pushing the extra gear range to the back. You can choose to shift at the front should you want to, like when youre coasting up to traffic stops. You will not be able to swap between 2x and 1x set-ups like you can with the Force and Red cranksets. Weight difference negligible. There's an 11-28t cassette in the works but still not available commercially. SRAM for innovation, Shimano for execution. The frame is made out of carbon and the condition is Brand New. With AXS I expected some improvement and a wider range of gears, but I wasnt totally convinced about how essential it would be. Bikerumor Copyright 2013 2023. ago. Both of those features make the best fit possible for any rider. Its only when all of the improvements come together that it all starts to make sense. Id only add that if EVERY media outlet is reporting nothing but positives, Id say its a pretty good indication of the groups merits. 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. Once you dial it in, I can see it being a cool thing for beginners or triathletes who dont want to have to think about doing too many things while riding. Then again, might it just live up to the hype? Colour: rainbow. The 10-26t, 10-28t or 10-33t can run with a standard Red derailleur. SRAM Eagle AXS MTB First Impressions, https://www.sram.com/stories/19-road-team-roster. Which means it could be a complete folly for us to describe SRAMs new eTap AXS shifting system in such terms.

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. Bike compatibility: Universal. The Rival cassette uses a fully pinned design, where 12 individual cogs are pinned together, increasing the weight by about 20 grams over a comparable Force cassette. I ride mile after mile on 50/34 chain rings, and the best part is that I dont have to throw away my power meter if I want a change. In comparison, Shimano's crankset is created using the brand's Hollowtech II technology. I keep waiting for the moment when their reach no longer exceeds their grasp.
