Hey everyone! Just wanted to throw this comment out here, thank everyone for viewing and everything. I was curious with this channel: What other content would you guys like to see in the cycling community? I am open to any and all suggestions. Just comment below and I can go from there!

hello i found a CS-MZ80 12 speed but 11-50t only. would this fit still ?

[@mvanalst2003]

Even though this video is two years old, it is exactly what I have been trying to find on KZbin. I wasn’t sure what way I want to go, but now I’m nearly positive I want to mirror this set up. I’m not sure if you still create content, but I subscribed none the less. Thank you so much for the help!

[@retroonhisbikes]

I did it. Converted the wife’s bike to 12 speed using the sunrace cassette, then sram nx chain, derailleur and gx shifter. Used her Shimano XT crank but with raceface single 32 narrow wide chain ring. So much easier than expected. Thanks for this video

Kudos for the video, I just order a new 29er wheelset for my farley 9.6 fat bike which already has Sram Eagle NX and just learned 30 seconds before placing the order that this Sram Eagle NX is to be set on regular Shimano/Sram hub. Almost I screwed up badly ordering a XD driver Hub instead. Sram Eagle NX is the entry level of Sram for upgrading to 12 sp, which is what they call PG techology Compatible with a splined driver body. If you go with superior technology which is XG, then you have to use a XD drive hub instead and the whole cassette comes all together within the same spider. Having this wonderful option from SunRace makes it easier to understand, affordable, and cheaper because we can reuse what we already have in our bikes. Kudos again for the info and video

[@ИванСмирнов-т6у]

I'm from Russia. One time I tried SRAM. Chain PC 991 torn from me not even after 1000 km (the stretching was not looking) I was then with contact pedals and wellabove. The chain lock and the squeeze is not taken (why? I have a new top chain PC 991. And for good reason. ) The house was 10 km away. Went to wellabove (not cheap time ) killed boots , rubbed to blood feet. Since then, only shimano , Deore and XT only. A very large resource, great reliability, the best clarity in the work, no unpleasant surprises. Per year rolls up to 7000 km Ride on the dust, forests, mountains. Dirt, water-very often. More than 9 stars on the tape - I believe in harm. Yes and 9 many. But nothing can be done about this marketing. My favorite system is of course the Deore XT , but with 48 teeth on the big star (48х36х26) 11х34 cassette 9-speed. With such stars can be accelerated on the descent to 73 km/h and drive in a very big slope with a load in the pants for 25 kg and with a backpack on shoulders for 15 kg. could be Better.

Have been using Sunrace 11x50 cassette on a 1x12 setup. Flawless shifting, weighs about same as SLX, and paid less than $90

[@glibsonoran]

Just FYI SRAM's NX Eagle Cassette (PG-1230) 11-50 will work on a standard splined Shimano hub too. Not sure how the weight compares to the Sunrace.

[@StopaskingformynameYouTube]

I recently converted from 3x9 to 1x12 sram eagle and for anyone doing the same, the sram alignment tool MAY work for you, but my experience is that the gap they want you to have is to big. I had to reduce the gap by many millimeter to get my bike to shift as it should.

[@danb37]

Hello I'm looking to do the same. Does swapping out a 10 speed to a 12 speed ever require a different free hub? Does using a 12 speed cassette from a boost hub on a non boost 10 speed bike work?

Good video. I made the change to 1x12 after watching your video. it was nearly £ 120 cheaper than having a full GX Eagle.

Sir! To me it sounds like you know what you are talking about! I am going to bring up a subject that most tech bikes freak out when I bring this up!!!! "I WANT A 3X12 DRIVETRAIN!" ALL I HEAR THAT IT IS IMPOSSIBLE TO MAKE HAPPEN!!! I have a 3x9 that I truly love!!!! I would love to see a 3x12, I challenge you to make it happen!!! I hope you put some serious thought into this idea and then make it happen!!!! Please atleast think about!!!!!

Ten years ago I was searching and striving to find a diy solution to fit a larger, 40+T cog on the cassette... and people laughed at me, saying "what the hell do you need such a big sprocket for? You'll end up pedaling without actually moving anywhere!" Back then, even the 14-36T freewheels were frowned upon and mountain bikes were sporting 32t at best. With a 32T *small* chainring. Now these cassettes are actually in high demand and pretty pricey...

[@leonardonibal5012]

Im a GX user also but i also used XX1 cranks

[@DIYManiacJohnP]

I would have swapped out that rear hub and converted to SRAM XD. This would have allowed you to use the SRAM GX 10-50 or 10-52 cassette. For chain sizing on a HT bike. Add 3-4 links when measuring chain over chain ring and largest gear on the cassette

[@oscars7948]

this was exactly what I needed. Thanks

[@DIYManiacJohnP]

I love my GX 12-speed setup

[@mtbboy1993]

5:47 just righten to it the point where the shifter and brake stay in place, but will move on impact, to avoid damage to the brake or handlebar, and use Loctite 243 to keep the bollts from loosing.

[@zenmoto369]

What I found out the problem to be is not the number of speeds but rather the missing bigger 50-51-52 tooth cogs on smaller speed cassettes. I can't imagine why would you need an 11 tooth on MTB. I've changed from 2 x 8 to 1 x 11 and I've never used anything after 8th speed and the bike is even used fairly often on the road as a commuter. I could have stayed which the 8 speeds, just give me 52T ring :D

[@chrisperkins4279]

Don't for get to lube the threads for the cassette retainer since you have two different metals in contact. Same for attaching the deraileur to the frame. Failure to do so can cause these parts to seize the next time you go to remove them.

Very helpful. I have searching on line and u did it. My opinion is that it depends on ur hub width. My mtb bike is 8 speed and has shimano standard hub which are 35mm wide. Can u tell the width of the shimano hub on which u have installed 12 speed ??

[@KennyMinigun]

BTW, have you checked your rear hub manufacturer's offer? They might have an XD driver freehub replacement part. IFAIK only Shimano does not supply such a replacement for their hubs. Decent hubs from other manufacturers should have this option available.

[@Gunnl]

With the SRAM eagle NX .. you also don't need to replace the old shimano style freehub

Mine won’t fit idk if there’s a difference between hubs depending on the cassette or what but I did the same thing. You can’t install the cassette wrong. My hub isn’t long enough like the body itself. When I put the last cog on it won’t grab the teeth.

[@Hawlkeye-e9p]

The only down shot this is the cassette weight. Some of these are cheap and up to 650 grams. The hollowed out high end cassetts are the best choice. Xdome i think they are called. But carry a big price tag.

[@gingaleanda]

Thanks for making the video as I’ve found the information useful:)

[@dancing8595]

Great video. Do you know if this would work with a nine speed Shimono hub?

[@KillerRaptorr]

Man picturing this being better with a 3x12 would be way better. Including if his front small gear ratio was smaller like 10or less then 20tooth. and his high gear was like 50+. This would give so much torque speed, and way fast top speed.

[@spagettmaster3429]

Well yeah but it would need a much longer derailleur cage to accommodate the massive range of gears

[@seven9766]

I get that you are joking, so bear with me: Making a transmission inside the frame? Hell yes! All that weight shifted to the center of the bike is awesome! 12 Chainrings? Harsh. The Shifting gets donen on the back because there the tension on the chain is defined only by the derailleur, not power pedalling.

[@io2738]

Woah I love that chain whip

[@TheTinyCyclist]

That is my dad's patented chainwhip! He made it from an old metal ruler and old bits of chain. Maybe I should do a video on it? It's interesting! He pushed a spare pin through a hole in the ruler, which allowed the chain to stay on there. It's got a Wal-Mart Bell Grip for a handle.

[@wolfmtb57]

I just want to know so I‘m getting it right. You had a shimano 10 gear hub at the back and switched to a 12 gear cassette. That‘s cool I‘m also thinking about setting my 3 by up to a 1 by system, but I want to get a good gear ratio. Do you think it should work like yours?

[@Eddieboy763]

Great to see you exploring the possibilies of groupset cross compatibilitiy however the biggest red flag for me after seeing this video would be the chainline. You did not replace your crankset. Most significantly (although still also prevelent in some 10 speed set ups) when running 11 and 12 speed the front chainring needs to migrate 2.5-3mm outwards (also referred to as boost spacing) to give the optimum chainline for all the cogs on the back, I can clearly see with your setup that the chainline is incorrect and possibly this is why you decided not to include the audio when indexing the gears as I can only assume it was quite apparent. Additionally these cassettes are only meant to be run with certain sized rear wheel spacing, I believe 148mm is the minimum with 135mm / 142mm again contributing to improper and ultimately unrectifiable chainline. Having inproper chainline not only prematurly wears out your drive chain but it can also lead to serious mechanical failures when out on the trail as the chain is more susceptible to binding and seizing against the cogs and even jockeywheels in some cases which will cause your deraillieur to twist and mech hanger to fail. Park tool have some great videos on this which may help you in the future!

[@s.nelson256]

I don't think the chainline is an issue on this, actually, because he wasn't changing from a non-boost hub to a boost hub. He was just fitting 12 speeds into the same space as the previous 10 speeds on the same non-boost hub. But had he switched to a boost hub (not even possible because the frame is likely not boost compatible) he would have needed to move the front chainring outboard.

[@katyreesimpson8742]

Why is it that the sun race fits the stock Shimano hub but the seam doesn’t? I just installed the SRAM NX groupset onto my diamondback and the freehub body itself isn’t long enough to support the very last cog, the smallest one.

[@grenfel6120]

They do weigh a ton. The weight of that cassette is monstruous. One could save 230 grams by spending an extra 100€ on a garbaruk 11-50. That is a spectacular weight saving per €/dollar/whatever ratio.

[@whssy]

This is my biggest niggle about these types of system too. Only reason for going so wide range is because you want to ride climbs AND fast fire roads. You're basically adding more than the weight of an extra chainring to a rotating mass component. Anything bigger than 42 I'd be going 2X11 TBH. Fitted a 1X12 system to a bike for a customer the other week and it left me very unimpressed, even though I'm running 1X11 on 2 of my bikes. Next investment for me will be DI2 2X11 with a single shifter.

[@glibsonoran]

The one thing you don't get on the standard Shimano hub compared to the XD Free Body or the Shimano Micro Spline, is a 10t high gear, due to the larger diameter standard Shimano freebody. Also the higher end X1 X0 cassettes that require XD are probably lighter.
