I've had nothing but problems with the new shimano 12spd. 2 failed xt freehub mechanisms that started creaking, then locked on and turned into fixed gear hubs. That was terrifying! Then the mail pivot of my slx rear mech corroded and the pulley cage no longer moved. Also, 3 xt 12spd shifters fail on me. On all three, one on the small springs that drives the shifts to easier gear/bigger cog breaks, then they can only shift to harder gears. Shimano has warrantied every I have listed, no questions asked. I do ride way more than most(endurance mtb racing is my thing) but this has been shocking to me, have had 11spd xt everything for years with zero issues. Think in the next year or two we'll start seeing massive recalls on all the 12spd parts as the average riders catch up with the mileage I put on my stuff.
Nx eagle 11-50 cassette with xt shifters and derailleurs. Compatibility with standard shimano freehub body and xt shift smoothness. Might be my new setup
Cheers Jack, and thanks for watching the video mate! It will be very interesting to see how much XT/SLX is spec'd on 2020 model year bikes, compared to SRAM Eagle. [ST Wil]
These 1X systems are nuts. I believe it’s a ploy by groupo manufacturers to sell more replacement parts. With a chain having to bend at the high and low ends across twelve cogs in the rear to a single front chainring, you absolutely know the chains and cogs are going to wear quicker. Chains will stretch faster and chain-cassette mating will happen even quicker. When I raced with a 3X7 system, The middle ring only had to bend across the 7 or 8 cogs in the rear. Even with chains now being narrower and the cogs closer together, it still means the chain has to bend at angles greater than in the past; and that’s not helped with the narrower chain too, which has less space between the outside plates to accommodate these greater angles. Inevitably this will result in replacing parts more often. If I were still racing, I would stick with a 2X system.
Me too, but the 2X is skewed too low in the gear range. Using a rolling diameter of about 28", the low gear is 16 gear-inches (I want about 18), and the high is 100, which isn't even as high as the 105 of my old 3x9 26” MTB. If the low gear was 18, and retaining the 623% gear range, the high gear would then be a much better 112 - actually a bit higher than my compact crank 9spd Tiagra road bike.
Since 2017 Sram Dominated with 12spd with AXS, XX1, XO1, GX, NX Shimano now has ...,XTR,XT, Deore XT,SLX so they are now almost even. But Sram is about to release SX eagle which is even cheaper
@@carlt9265 I made that 2 years ago when Shimano didn't have cheap 12spd drive trains and they were very similar in reliability. Now Shimano is better definitely
Just ordered a setup for my 2018 trek pro-caliber 6:-) that had a 2x 11 set up. I'm an old fart who doesn't really need it, but it's fun. you will actually have a little bit more of a granny gear than my old 2x 11
It would be really nice if Shimano would drop the word Deore from the XT branding. Everyone just calls it XT anyway and it just leads to confusion with the Deore (lower end) level.
Very interesting! i was close to get a new bike with the SRAM GX group, and after your review, ill wait for the new XT to reach the stores and see if I can get a good deal in a bike with it.
Apparently the XT groupset will become available in its more popular configurations in the middle of June, so only a couple of weeks away. Expect to see 2020 model year bikes rolling out with XT & SLX specification in the very near future too. [ST Wil]
Makes me so happy, in 1 year from now People Will Wonder how The hell they could run gx12s, so fragile, a diva to set up, now we can ride a 12s drivetrain . Set and forget, love you shimano ❤️
@@gustavbergstrom1502 i never used a 12 speed group before, but i had a bike with Sram and now i ride one equipped with Shimano. So far i liked both, and, in my opinion, Shimano being a bit superior.
nice, but I will stuck with 11-46T x 32T oval, I think I can go even lower without loosing too much high end, but 32T seems to be the sweet spot for high end. I am climbing steep stuff, also going down fast steep stuff, and long straights, so pretty decent range. but I don't think I would need a such big range, but I have nothing against them.
Me too Jeff! Fundamentally the mechanism is the same as the Scylence freehub, but the ratchet plates don't completely disengage, which is why you get some buzz. It's still one of the quietest freehubs I've used though. Apparently Shimano wasn't 100% happy with the Scylence system. The prototypes tested fine under normal conditions, but in the torture lab, they found they could occasionally get some skipping. I was told that this would be extremely difficult to replicate by a human rider, but it was enough of a risk for Shimano that they pulled the design. Consequently, production hubs were changed slightly so that the ratchet plates remain in contact with each other while freewheeling. Again, it's a pretty quiet buzz. They're still working on it though, so we'll await an update on when we're likely to see that come back, and whether it's something retrofittable to the current rear hubs. [ST Wil]
4:12 but will the cover stretch and fall off on the trail? so dirt comes in ? this is the issue which happens with M8000, the rubber hood is awful, the ring that holds it in place gets bigger, eventually falls off, the hood also pops off. awful. this happen once, then I bought a ned installed it and happen in few weeks. I don't know why, if it reacts to cleaners(muc off in my case) or heat,cold, or contaminants from the trail,road, or what it is, or if it's just the nature of the material they use.
I know your question is 7mths old and you may have made a decision by now, but I've just dumped a 2yr old GX groupset for a XT 12 speed and it's miles better. Looks nicer,runs like a dream. The shifting is so much more positive and instant. Maybe it was set up wrong but I was NEVER happy from day 1 with my GX set up. No amount of adjustment could get it to run smooth. I'm not a Shimano fan boy or Sram hater but I certainly prefer the almost fit and forget nature of Shimano stuff.
5:48 I don't think it will fit me anyway, the problem with previous version of shifters were I am hitting & rubbing the grip,lock on clamp, at up shifts I run 34mm RevGrips. 6:14 definitely a nice upgrade, I could see the brakes flexing when braking if I looked at them, it was like that on several brakes I used, but all were budget options, M15,M396,M6000, but last one was stiffer, but has some play in the lever clamp probably due to the I spec plastic thing,but not much, but the body sure is flexing, so good they have worked on that. But I hope the pistons seals will last more than a year.
Arithmetic still rules - as in, 2 x (or, sadly, 3x) anything will always provide a lower low, higher high, and closer gaps between gears, because, uh, you know, 2 times 9, or 10, is more than 1 times 12. Duh. But, hey, marketing and planned obsolescence rules, whether or not the inherently greater inefficiencies, wear, and stresses on an ever skinnier chain and 10 tooth cog matter to the next crop of newbies ignorant of the history of gearing. Same for cramming 29" wheels again, despite tests showing 27.5 optimizes weight versus rolling resistance. I'm sick and tired of frame makers eliminating mounts for front derailleurs as in truth mostly a fashion statement and play to those who think they are among the 5% who can actually clean steep uphill terrain without granny gears.
it was good debate, tbh i had same thinking as you before but the more i look into 1x the more i understand why it's need to be 1x drivetrain advantage 1. less noisy bike 2. optimize for rearshock and sensitivy 3. cleaner look 4. weight saving 200-500 gram depending on what FD you use
not so easy ;) you must change rear wheel, or only rear hub if you want to ride with 10t cog. There is the same situation like with sram. New cassettes neds new special Micro Spline freehub. But you may switch to 12 easier, if you use some cassette for old freehubs, like sram NX Eagle PG-1230, or Sunrace CSMZ90. Both with 50t, but the smallest cog is 11t. But I thing old 11 rear mech will work with 12 index.
@@hgwhgx5188 I have Mailed to DT Swiss and they hey aftermarket Micro Spline Hub why internet site's say they think there is a patent conflict because the Shimano freewheel hub looks very similar to the DT Swiss hub and Shimano allowed DT Swiss to make one.
