Read more…. After my third ride, there was no reason not to embrace this system for any trail bike where long, sustained climbs and a variety of terrain are regularly encountered. With a single chainring in the front, and a 10- or … Ride your bike and enjoy. 1x setup. Having trained for a two-minute event for most of my life, higher gearing allows me to pull away on punchy hills and flats. phuddy68 The range of gears is fine, that’s not the problem with a 1x setup. 11-36 for hilly NH dirt and gravel. At the rear, I changed the cassette from 11-32 to 11-40 to get more range and better climbing possibilities (to make this work I also needed to replace the rear derailleur for Shimano 7000 GS long cage one and use a longer chain). To make everything more interesting, I will compare rather extreme cases of both 1x and 2x drivetrains. No matter if under load or not, SRAM ETAP is a joy to use and you don’t need to think about the gearing at all (but you definitely have to think about the battery being loaded because otherwise there will be no shifting at all). This is the terrain where a 2x excels. So, which do you prefer? The other one would be something like a good all around bike. When riding on Canyon Grail there were situations when I felt that I could travel a tad faster but when I switched the gear, it became too tiresome to maintain the cadence so I had to slow down and then switch back to the previous gear. So you finally got yourself a mountain bike with an aluminum frame, fixed seatpost, 26 inch wheels (with inner tubes of course) and 2x10 drivetrain and are ready to hit the trail. It is somehow frustrating not to be able to ride at the edge of your (in my case rather limited) abilities. SRAM introduced its 1x (pronounced "one-by," as in, "1x11") groupsets on mountain bikes in 2012. I've got one 1x and 3 2x mountain bikes. A standard 53-39 2x11 drivetrain actually … Almost a year later, I couldn’t be happier. You click and it is done. I'm currently running a 2x10 setup with a 26/38 crank set and a 11-36 cassette. Gravel bikes these days are divided between 1x and 2x groupsets and it is up to us to decide which solution we want. Sharing in-depth conversations between the world's adventurers, athletes, and outdoorspeople, The GearJunkie Podcast is your inside look into the outdoors industry. I do enjoy (and use) the big … Like 1x, 2x shares the same inconvenience for most of us that our bike becomes totally useless on road sections or even, dare I say, going remotely … 1x drivetrain usually also means a bigger tire clearance but to be fair, new GRX derailleur is designed to achieve the same result with 2x setup. SINGLE-RING SIMPLICITY We swept aside unnecessary complexity with a simple, reliable MicroSHIFT single-chainring drivetrain. Or at least I can show you the differences that I can see so you can make a more informed decision. Triple chainrings, doubles and now single ring drivechains; we’ve never had so much choice in MTB gearing, but which is the best for you? Yet I can totally understand those who fall in love with 1x setup. My site is all about gaining as much comfort as possible without losing the fun of the ride in the process. As with tire pressure and suspension, cyclists can hone their gearing to yield greater efficiencies. Old Shimano 105, that I have, was causing a lot of issues when I was experimenting with big tires at the rear (basically I could not use the bigger chainring in those situations even the frame itself was still having enough clearance to accommodate the tire).So, who wins a convenience battle? LOVE THE … https://www.cyclingabout.com/1x-2x-3x-drivetrain-for-touring-bikepacking You use left shifter to go for easier gear and right to go for a harder one. There are two SLX quality 11 speed cassettes available of 11-40T (which seems anorexic in the age of Sram Eagle) or 11-42T, with 1x riders able to choose between 30T, 32T or 34T chainrings. In my case, I use a CX oriented crank - 46/36 with a wide spaced rear der. First, before we jump right into gearing, a quick discussion about the biomechanics of the engine — in this case, the rider. You can see that the high gear on the compact double-GS is 123 gear-inches and that the lowest gear is 29 gear-inches. Then you pick up a mountain bike magazine and realize your bike is not "cool" and is totally out of date and too heavy. At … This is something I have been doing for a long time now on all of my mountain bikes, so let’s get into the nuts and bolts of what you gain and lose by converting to a 2×9 setup on … Of course, the difference could be bigger in 2x favor when changing the front crankset for GRX 48 / 31 (which I will do on my new benchmark bike), but then the max speed would be slightly lower also (but still you would travel faster than on 1×12 setup of Canyon Grail bike).So, the max and min speed difference is not that differentiating between two tested setups but now it is the time to talk a little bit more about the jumps between the gears. I’ll be going 1x eventually, but I gotta wear out my 3×9 drivetrain first haha. Ended up going with 2x because I do ride in groups quite a lot and the smaller jumps in ratio make it easier to settle on pace. What I mean by that is the crankset movement that makes the derailleur adjustments much harder and without that, chain robbing the derailleur will make you at least, slightly irritated. In particular, it does well in situations where biomechanical efficiencies are not profoundly compromised — flat terrain and courses with abrupt changes in pitch, with fewer long, sustained climbs. I really think that on my steel Jamis Renegade bike I would not feel that frustrated when riding on 1x setup but still, now I can appreciate the gear range that 2x drivetrain offers. The 11-40T cassette weighs 467 grams, which makes it lighter than the NX by 70 grams (with a smaller range) but far from sprightly. The electronic shifting is so much crisper than mechanical systems. “In my experience — and the research generally agrees — cyclists operate best within a pretty wide range of cadences,” Carmichael told us. The 1x drivetrain uses that 10-51T cassette and then a chainring size of your choice ranging from 28T-34T. With limited high and low needs, your remaining gears will be more biomechanically efficient and spaced with smaller jumps in between. In terms of weight I don't even notice. Yet when you go down, you also have to go up and in this scenario, the difference is even smaller. Not a lot but it can become handy when you ride downhill a lot. Is the gear you’re in the most efficient, or are you just surviving? In those instances, gearing must accommodate pedaling hard at 50 rpm to accelerate to 110 rpm repeatedly. There might be a weight penalty, in this case about 200 g, but on the terrain I ride most often, it’s worth every bit in biomechanic efficiency. Meanwhile, 1x drivetrains often had me wishing for a couple more (or fewer) teeth in certain situations. With 2x drivetrains going the way of the dodo, it seems obvious that a single chainring is better. Ditch the shifty bits. © Copyright 2021 GearJunkie, All Rights Reserved, Atomic Maverick, Maven Ski Review: Built to Shred North American Slopes, Watch: This 80-Year-Old Park Skier Is Still Ripping, Natural Selection Tour Unveils Final 'Wild Card' Riders, Today's Bargains: 4 Cold-Weather Essentials, Simply Advanced: Stanley Titanium 'Multi-Cup' Is a New Camp Favorite, The North Face's Record-Breaking Shoe: Flight VECTIV Trail Runner Review, Lightest, Most Efficient Backpacking Stove Ever: Jetboil Stash First Look, Camo on the Slopes: World-Class Skier David Wise Is Also a Pro Hunter, Tree Saddle or Treestand? It means that going is very much the same hassle on both bikes. Round 1: cadenceThis is a very complex topic, so let’s break it into smaller parts. Unfortunately, if you were to remove these rings and install a standard narrow-wide ring the resulting 1X chainline would be about 52mm. And yes, it's real. When the trail calls, you gotta answer, which means having the right bike for the ride. First is the speed that you can travel with at the lowest and highest possible gear. At the front, there is a standard Shimano 50 / 34 crankset but everything is paired with brand new GRX 810 leavers (because I wanted to finally have fully hydraulic brakes – up to this point I was using a TRP Hy/Rd brakes). Shimano’s Synchronized Shift 2x system uses one right-hand-mounted shift mechanism. This leaves 2x in the domain of everything else, particularly well-suited to courses and terrain with rolling features or long climbs. With 1x drivetrain, you don’t need to worry about anything. Not just 1x or 2x but the cassette range that works best for you. Based on the settings you select, Synchro figures out if the big or little chainring should be engaged to maintain the ideal cadence. Whether it’s a Z-drag pulley system pulling a pinned raft out of a river, or a seven-speed dual-clutch transmission tied to a 700-horsepower engine in a Porsche GT2RS, proper gearing translates the energy input into usable work at the other end. To calculate that I used this website and the data says that at 90 RPM cadence the speed you will achieve on a 1×12 setup is 50 km/h (700c 40 mm wheel, 42×10 gear ratio). You just keep the chain lubed and enjoy the ride. Your preferred cadences and the terrain you’re rolling over should be the determining factors in gear selection. No adjustments needed even when your crankset is not working in perfect line anymore. A 2X crank with tooth centerlines that are located at 45mm (smaller ring) and 53mm (larger ring) would have a 49mm 2X chainline. The easiness of use is really addictive and after spending a lot of time with SRAM ETAP 1×12 setup it was hard for me to go back to my 2x bike. The steps are always too large to find the ‘right’ gear.”. The 1x drivetrain has all but killed the multi-chainring setup, at least on mountain bikes. On Grail there is ETAP Electonic shifting that works beautifully. It is all about the bike you have and the rides you usually do. And, though Carmichael spoke to the adaptability of cadences, the key is to find your most efficient bandwidth. “About 60-120 rpm at the extremes, with most people performing best at 80-100 rpm.”. And the interface works as you’d expect: Shift one lever for an easier gear, shift the other for a harder gear. How to convert your bike to a 1x drivetrain. I normally ride alone and my steel bike is not that power efficient and fast so it could work with 1x setup. Historically mountain bikes have had either 2 or 3 chainrings mounted on the cranks which used a front derailleur to move the chain across them when shifting gears. At Wolf Tooth, we were at the forefront of this 1x revolution and want to share a summary of the most important points for 1x gearing, mechanics, and optimization. We asked five pros how they made it work and what it takes to make a living in the outdoor industry "in real life.". 03-15-2017 #26. grubetown. The chart above (click to enlarge) shows how the different XX1 chainrings with that oversized 11-speed cassette stack up, helping you choose the right front chainring(s) for your riding. Curious how switching from a 2×10 drivetrain to a 1×11 group like XX1 will affect your gearing? Nowadays, all of them come with 1x drivetrains, especially since Sram and Shimano introduced one by to their cheaper drivetrain ranges. The crankset is direct mount this year, it looks like it is pinned in four places with a spider set up as it was last year but it is in fact direct … The one or two refers to the number of chainrings on the front of the drivetrain, while the second number (10 or 11) refers to the number of cogs on the cassette in the rear of the drivetrain. Discussion Starter • #1 • Jun 30, 2017. And the winner is….I don’t think that we can a clear winner in this battle. 21 December 2013. Sanny has been left on his own for too long again and has been casting his critical eye over technological progress in the 1x drivetrain area Since it was built, the system has required zero adjustments. When it came time to take delivery of my full-suspension Specialized S-Works Epic, the only option was Shimano XTR M9050 Di2 with a single chainring. Of course it would probably do you just fine but now you are wondering if you can do … Two common choices among mountain bike riders are the 1x11 and the 2x10. In short, 1x was great for its simplicity, but at times the gear I was in never hit my cadence sweet spot. The 46/36 is a standard crank offered by most manufacturers. “On the flats, there seems to be less variability, with riders generally adopting a cadence of 90-110 rpm,” said former pro cyclist Dr. Missy Thompson, professor of biomechanics at Fort Lewis College in Durango, Colo. “However, with climbing, there is considerably more variability.”. 3Mm wider than the ideal 49mm 1x chainline but makes up the vast majority all!
