I've Scott Metrix 20 and I want to upgrade groupset to Alivio M4000 series.

Hello folks. I own a Scott Metrix 20 hybrid bike. It has Tourney and Altus gear components. I want to upgrade it to whole Alivio M4000 Groupset. I got a lightning deal and I'm a bit skeptical about its compatibility with my bike. Is Alivio compatible with Scott Metrix 20?

Can't find a "scott metrix 20" with that spec.
If the same number of speeds, I'd be hugely surprised if it didn't work.
Although, apart from the rear derailer - which for Tourney is kinda clunky - I really wouldn't expect much improvement while JRA.

Double posting is kinda frowned about here.
And is marginally useful WRT getting more/"better" answers.

Scott Metrix 20 2017 model. It has 3x8 speed. RD-Altus M370. FD- TX50. I'm doubting about 9 speed RD and bottom bracket compatibility

It depends on what you mean by the whole groupset. A pair of shifters, RD, FD, Crankset, Cassette, chain and possibly brake levers if the shifters you are replacing are combo shifter/brake lever and the new shifters aren't (M4000 exists in both separate and integrated controls AFAIK). If you're going to swap in a 9-speed cassette, go for it. You won't have any problems. Otherwise, the 9 speed shifter won't work with an 8-speed cassette.

Front derailers work on the tensioned side of the chain.
The biggest improvement you can get on front shifting is to ease up on pedal pressure while shifting.
It’ll take very particular circumstances before I’d consider a front derailer replacement as worthwhile.

8/9-speed rear shifters and derailers are - for your models and vintage - fully compatible.

Please explain your concerns about the bb.

Please bear with me. I'm new here. A bit confused with thread format. While trying to quote comments I'm being asked title again.

It might work, but I would ask why? Your proposed upgrade would seem to offer modest improvement, maybe almost non existent, for the expense. I know Altus is just a step up from entry level in Shimano's mountain bike groups, but Alivio is just a little better. And, while Altus is fairly heavy, it should function virtually identically to Alivio.

Welcome!

Your biggest improvement will be in the shifters and in the rear derailleur. Much of the shifting performance and feel comes from the shifters. Your bike likely has Shimano Revoshift twist shifters or lower level Altus shifters right now. The modern Alivio ones will generally work crisper and quicker, especially if you have Revoshift twist shifters. The rear derailleur is of a much different design than your current Altus derailleur -- the M4000 series uses Shimano's relatively recent "Shadow" technology which is a hand-me-down from nicer MTB groupsets. It keeps the derailleur much closer to the rear cogset for better clearance, and also uses different cable routing, so you don't have that large cable loop in the back common to Shimano derailleurs. Chain tension is also improved...it works more like a Sram derailleur than a traditional Shimano unit.

Because you're replacing the entire groupset, you probably don't have many compatibility problems to consider. The rear derailleur hanger should be the same design, and your shifters control the number of gear combinations you have. Alivio M4000 is usually 9-speed, so you'll need a 9-speed cassette and a 9-speed chain. This is probably your only potential issue -- if your bike uses a freewheel in the back, your wheel and hub will not be compatible with a 9-speed system. You'll need a wheel and hub that can accept a 9-speed cassette.

I upgraded my 2000 Trek 720 MT from old C201 to Alivio M4000. Shifters, deraileurs, v brakes. I replaced the crank with deore m622. For me this was an upgrade from 3x7 to 3x9. Also a kg weight reduction. Definitely a significant improvement.

Curious if this is the Scott you have?

If this is the bike you have, then you should be fully able to swap out to the Alivio groupset. Heck, think that Altus rear derailleur is a 9 speed derailleur, but used for 8 speeds on this bike.

Not really sure if you are going to see a significant difference in shifting, I say this because I'm not sure what new 9 speed cassette came with your groupset. I have the M4000 Alivio rear derailleur on my Crosstrail. I have a wheel that has the HG200 cassette (used for my trainer) and another wheel that I have my HG400 cassette for my actual rides. There is a significant difference in shift quality between those two cassettes. It's very possible if you just got an inexpensive cassette like the HG200, you are not going to see any difference in shift quality. Just adding a gear.

I'm assuming you have the Altus shifters on the Scott now. The M4000 shifters are more nice, I have compared them since my son's old bike had the Altus shifters, but it's not a huge improvement. The M4000 shifters are a bit snappier which does make it feel better.

For Shimano MTB up to 9 speeds, all rear derailleurs are interchangable. The difference isn't the number of gears, it's the build quality and materials. The RD-M4000 is really a previous Deore rebranded, IIRC RD-M591. There is a big difference between Altus and Alivio.

That said shifters have a more significant impact on shifting than the rear derailleur. Swapping out the right shifter and the cassette would greatly improve shifting.

You had upgraded your old Altus C201 to the Alivio M4000. Yes, most definitely that is a significant difference.

The OP is talking about upgrading a Altus M370, which is a significant upgrade to your old C201. The M4000 Alivio while is an upgrade to the M370, it's not the same significance that a Altus C201 to the Alivio M4000 is.

Both the Altus 370 and the Altus M2000 alike the Alivio M4000 has trickle down tech from Deore. But there is a difference, Deore build tech is better being that it's all metal. The Alivio M4000 and Altus M2000 uses plastic. Granted I haven't seen any problems with mine and it works fine, but for heavy mountain bike usage, metal might be better than plastic.

For a typical tourer who is not riding down mountain sides, none of this really matters, there just isn't a significant difference in quality between the newer Altus and Alivio's. What's even more interesting, is that Shimano no longer even has the Alivio on their web site. Only the updated Altus.

If the OP likes what he/she is spending money on and will make the ride more enjoyable. Then great, money well spent.

Alivio (M4000) is on their website, on the MTB Groupset page. Here's the Alivio M4000 specific page.

The significance with Alivio M4000 is the Shadow technology in the rear derailleur. As far as I know, it's the "lowest" of Shimano's hierarchy with this technology. More about the benefits of Shadow are on Rideshimano.com.

I've used both SRAM and (traditional) Shimano, and I really prefer SRAM's style of rear cable routing and specific chain tensioning design (which differs from traditional rear derailleur design). Shimano's Shadow derailleurs are closer to SRAM's design than their traditional designs. I'm glad to see them going this way, because I think it's a superior design. Its roots are in MTB, but there are few downsides that I'm aware of, even for city/hybrid bikes like what we ride.

Ah, yes it's still on the southeast Asia site.....It wasn't on the North America site: Home

Mostly agree, but there is meaningful difference be M370 and M4000. M4000 has shadow which has better cabling and the m370 is designed to accommodate freewheels. Also the plastic used in M4000 is fiber reinforced and carbon fiber. M370 uses "resin". Also, IIRC, the springs are stronger in the M4000 with results in more repeatable shifting.

That said, I would advise the OP to replace the rear shifter and cassette first. Then the derailleur is still not happy with the shifting.

I have used Altus, Acera, Alivio, STX on different bikes and different generations, some of which could be more than a decade old when i bought them, and never noticed any difference in shifting quality. Maybe i am insensitive but i am happy with what level of components my bike happens to have.

It all makes a difference, but is it a meaningful difference? I am not a fan of pulling off new parts for a slight upgrade without having a reason. Particularly on a hybrid or city bike. (I have seen upgrades on mountain bikes actually used for single track and that makes more sense. ) If I were OP, I would ride with the stock components until they fail or wear out. OP might be pleasantly surprised. Fwiw, I have been in charge of the family bikes for 20 years now so have experience with all kinds of shifters and derailleurs including vintage Simplex, Suntour and modern Tourney, Altus, Acera, STX, Deore LX and XT, 2300, Sora, And Tiagra. And very old (20 years old at least) Ultegra and 105. They all work well when properly adjusted. The only ones that failed were the Simplex front, and those were almost 40 years old.
