I think the 2x goes for a very different segment: long rides on mixed terrain with not only steep, but very long climbs, descents and plains to work with because it offers a better ratio, and the longest the climb, the more you tend to appreciate more a better ratio than a better weight IMO, especially if the difference is not that much. A 32x51 1x will give you a 0.62 ratio for the lowest gear, which is slightly better than SRAM's 32x50, but a 26x45 will produce a 0.57 ratio on the lowest gear, which is noticeable when there are a bunch of long climbs in the trail.On the other side, 32x51 will give you 3.2 meters on the highest gear for plains and descents, whereas a 36x45 will give you a 3.6 meters ratio and then again, the longer the descents and the plain sections, the easier to move at the same or higher speed. You can equal or improve the lowest ratio in a 1x system by installing a smaller chainring, but then you're reducing the highest ratio in consequence. So, as I see it if you run some laps in a bike park a 1x would be really sweet, but if you're running on natural trails for long rides with mixed terrain, and especially if you're getting old or you have any kind of leg injuries or problems, the 2x will be better on the long run because of the better range in both directions while keeping the cool tech benefits; honestly I don't remember any time where I had a front derailleur issue in a ride.

And 2x10 (for example) will be MUCH cheaper and last longer, since all the sprockets are steel. I doubt there-s much weight difference, an 11-36 10sp xt is 200gr lighter than this slx 12sp cassette !

@@tonycaluda1868 2x10 is a great option as well, but if you need to climb steepest terrains I'd rather go with the wide range options that's where 11 speeds become slightly better, because the jumps between gears are smaller for having an extra cog, affecting slightly less the cadence, but that's a minor that may or not bother people. For example, a SunRace 11-46T 10 speed cassette has one step of 5 teeth and two steps of 6 teeth, whereas an 11-46T 11 speed cassette also from SunRace has only one step of 6 teeth and no 5 tooth step and if you want to keep all cogs in steel, you need to go down to 11-42 which reduces the ratio a bit 😰 there's a lot to think about indeed when you think about drivetrain combinations and options. Then again if you can climb everything with an 11-36T or even an 11-42T cassette then it's a no-brainer, 10 speed is the best bang for the buck.

What I don't like about this release is that up to this point to me 2x also meant reasonably priced and cheap to run, while 1x meant $100/€100+ cassettes. I know the prices are gonna go down, but even if you dig up articles from years ago about the announcement/release of M7000 and look at the MSRPs back then, M7100 is almost twice as expensive as of now. And guess what, as of now the MSRP for the cassette is around a $100/€100. Big range is great, but the cassette prices and prices in general are getting a bit ridiculous. An M7000 11-42 goes for around $50/€50 and with the combination of a double with a 10T difference it gives you ~530% gear range which is still pretty darn big. I'm very curious to see if this is gonna pump up the prices of complete bikes too. IMO nowadays lower end stuff like Deore M6000 works so good, but most of the time you only see M6000 on lower end complete bikes with crappy forks and crappy wheels. And of course if you want to build up a new bike with all new stuff from the frame up it's gonna come out so much more expensive.

@@Asthbendriel i have a 24/38 chainring and a 11/42t cassette and even with this massive low gear ratio (0.57) i barely get to the top of the hill (it's not so long, maybe 900m, but very very steep). So if i would change to 1x12, to keep the same ratio i would need a 30t chainring (ratio would be 0.59). But i also like going really fast down the hill and on the roads, and with a 30t chainring i would be much slower than a 38t. I've had SO. MANY. PROBLEMS with a front derailleur in the last years, chain rubbing on the derailleur, missed shifts, re-adjusting cable tension and limit screws every 2 months... And i really want 1x. But i really want the huge range of 2x. So i'll probably wait for 1x13 with maybe a 56 or 58t max cog wich will allow me to have a 32 or 34t chainring and still climbs easily and go fast.

@@Andrea-qg5yk you can make the switch to 1x if you want, your legs will become stronger over time but you'll be missing the top speed for sure, as it was my case a year ago when I moved from 2x9 to 1x11. My brother in law broke his drivetrain and he was broke so I gave him mine, and I did the switch to 1x just to try it out; I was using a 22-36T front chainring and a 11-40 cassette on the back, so I had an even lower gear ratio of 0.55 when I made the switch to a 32T chainring and a 50T cassette. The loss of range was noticeable in both directions, it was harder to climb steep or prolonged climbs and the bike was spinning a lot more in the plain sections, even while having a smaller 36T compared to you riding a 38T with your 2x. One year after I made the switch, I eventually got used to the range and now I can climb the same or even further with a 0.64 range then I did with a 0.55 back in the day, but I still do miss the top speed a lot in many situations in both fireroads and asphalt sections when you're connecting trails in a long ride. I did not have any major problems back in the day with the 2x9 in terms of malfunction, maybe a stuck chain once or twice in long rides because of poor gear shifting because of me entirely. On the adjusting side of things, SRAM drivetrains tend to need adjusting every few months as well in 1x, a friend of mine has a SRAM NX Eagle and he does need to adjust it every few months to avoid excesive noise.

Compared to a 9spd cassettes the cogs are closer together, they're also thinner so you need a 12spd chain, and the cassette uses a completely new freehub standard. I see no point in hacking together a 9spd setup, but you wouldn't be able to do it anyways.

@@HollyBoni If the splines of the hub are same. Then it'll still use the standard shimano cassettes. Just cause the inner functions of the hub itself are different. doesn't mean the outside attachment is also. The general idea isn't the thinness or different usage of chain. It's if someone doesn't want to use a large speed size. So if they don't wanna go 12speed, but want that kind of cassette. then using it's 12speed cogs to fit only just 9 of those, would give better range and keep it even lighter.

Singletrack Magazine it’s because shimano leave an expansion gap to stop the pads buckling when they heat up because they’re not smart enough to know that if you make your pads a bucket shape like sram the pads don’t need an expansion gap so the rattle inside when braking on rough ground also pulling and pushing on the porous ceramic pistons letting air in which makes its way to the lever and gives its that random bite point that’s been plaguing shimano brakes for the last five years. Have they done anything about that? 😂 Nice advert though I’m sure shimano have suddenly stopped making trash overnight.
