Looking to upgrade from 3x8 to a 1x. Have read good things about Advent X. Both are comparable on price. Looking for recommendations for either. Thanks community

I have an 8-speed Advent system on a somewhat vintage Diamondback rigid, steel MTB and it functions perfectly, but am a big fan of Shimano too. The Advent ($71 for derailleur and cassette - 11/50 AIR) works great and I selected it to try something different (probably price too).

Depending on the bike if it is a decent frame and had decent components on it, it would be worth upgrading. If not save the money for the bike you want.

In terms of X vs Deore, I would probably go Deore 11 speed but I will say that Advent X is not a bad bit of kit. Nothing blow your mind great but for the price is certainly a solid set up and the ability to run drop bar levers is really nice. Something Shimano hasn't fully grasped yet (though GRX is getting us closer). For wider range stuff I like having more gears as it is a smoother transition between gears which is a big reason for going Deore. Plus Shimano is pretty ubiquitous and easy to find parts for for years.

Advent X is compatible with itself and while they are currently supporting it and likely to continue for quite a while I do worry what might happen down the line when I want a shifter. I know with my Shimano stuff I can always find something pretty easily even if lower quality. Not that it is a major worry as I doubt you will have an issue if you maintain your stuff well but it is another thing to think about. However I do really hope that Advent X is around for a while it is a good quality entry level mountain bike groupset and we need more of that.

It’s diamnondback axis 27.5” so a good entry level groupset like advent or deore should do just fine??

I actually have both and both work fine. Here is my opinion.
1. I don't care about the extra gear 10 or 11 whatever
2. both bike run a 30 tooth chainring and I really don't notice any difference between the 48 vs 51
3. advent x cassette is about 200 grams lighter
4. I run an XT shifter on the 11 speed and I do miss the double up shift with advent x
5. advent x is on my full squish and gets ridden way more than the hard tail with deore
6 the old advent x Rd is kinda ugly, the new sword gravel RD looks better and the same pull ratio

Advent X uses the same pull ratio as 11 speed deore so I'm running an 11 speed deore RD after wrecking and bending the crap out of my RD and hanger, deore RD was cheaper. What it comes down to is both are fine. Get whichever one is cheaper or if you are like me and just want to try something different go Advent X.

Surprisingly it does have an air fork (assuming it is the one I saw online at REI) nothing great but that is rare on those types of bikes. Yes it will do just fine. I would also consider saving up for the bike you really want but this is an OK candidate for small upgrades.

Canker #5 isn't fair at all. Of course you will want to ride a full suspension bike more then a hardtail if you have both. It is rare to hear the opposite. If I had a full suspension bike I would be running that way more than my hardtail and if I get the full suspension it will replace the hardtail (though I will keep the frame)

I've built up bikes with both Advent X and Deore (but 10 speed). If the price is the same, I would lean towards Shimano, because IME it shifts a bit more smoothly. Advent is a little clunkier by comparison--not bad, but it's tough to beat Shimano. Advent does have a bit more range, though.

This is Shimano's new option for 9,10 and 11 speed drivetrains and cranksets. They claim it is robust and will last up to 3 times longer. It is only just now appearing on vendor's websites (eg Jenson) so I don't know when it is really going to be readily available, but I am holding out to do a drive-train upgrade on an olde mtn bike until I can take a close look at this option.

Canker

#5 true but I meant it more that I like it well enough that I left it on the bike I ride the most rather than swapping it over to the hardtail.

elston1999

That's another variable to consider with the addition of cues. Deore is said to be great for entry level riders but if this Cues is 3x stronger, I don't know. Looks like only about $20 more per groupset. I got some more homework to do. Thanks for the info!!

I installed the Advent X on my hardtail. It was a solid system. I had no worries about it breaking when hitting branches or rocks. It did clunk a few times when shifting, so as odd as it may sound, it was a satisfying kind of clunk since it placed the chain on the gears without any hesitation. Just forewarning you, since I don't see anyone stating it. The Advent X shifter is a push push shifting mechanism. You won't be able to pull the shifter into different gears. It's easy to get used to though. To the point, that all my current bikes with SRAM and Deore 12speed, I only use the push push shifting and not the pull.

Now, if you want smooth shifting, like others have stated here, go for the 11 speed so the gear range is spread out more evenly.

Don't think you can go wrong with either choice.

9 speed and 10 speed are now available from Jenson, and I just saw 10 and 11 speed Cues Di2 rear derailleurs on the REI website. I had no idea ...

CUES seems like a great idea if it is real then I would go for it. (I know it actually exists) Seeing stuff in a catalogue and in ad copy is one thing but in real life is another though CUES seems like it is quality. I remember the roll out of Claris and saw pictures and thought it could be decent and then in real life it was not what I thought it was going to be. It looked a lot worse.

my wife has a c-dale dual from 2020 that's been upgraded with 12sp XT, hope pro5 hubs, magura trail SE brakes, and carbon tubeless rims, she usually passes the bike off to ride a 2022 Deore/SLX c-dale Trail 3 SE. i would have thought the dual suspension a better option but she mostly doesn't agree, go figure.

OP, i've tuned and ridden several bikes with both groups and would buy based on which is the best deal. Both are decent off-road groups, durable, reliable, easy to set up and consistent in just working once the cables have stretched. 10sp vs. 11sp, 11 can be a little smoother shifting due to smaller jumps but i think the advent has a 4 tooth smaller cog in the back that keeps the shifting equally smooth.
