SRAM 12 Speed Conversion (Shimano Hub)! 

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!

Even though this video is two years old, it is exactly what I have been trying to find on RU-vid. 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!

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

this was exactly what I needed. Thanks

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

Thank you thank you for this video build! I have 2x10 set up and almost have to settle for sram nx 1x11 due to my wheel can fit gx eagle. Now this is my next upgrade even it's 11-50 instead 10-50, and heavier. This will save me so much money and weight!

i took a shot every time u said shrame instead of sram.....now im watchin for the third time : )

This is awesome. I have a 2016 stumpjumper that came as a 2x10. I changed out the front ring to a raceface 34 tooth and now want to go with 1x12. I didn’t want to buy the whole groupset and will go this route now. Cheers!

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.

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

Your Dad is a boss Oh and nice little tune you have there!

Great video, hope your father likes the upgrade

my dream bike 😢❤

Great video, now if I could do this to my Sram Apex gravel bike, that would be so cool!

Awesome video !

Excellent video. You two forgot the housing cap on the shifter end though it appears.

I just ordered the same exact setup but with Gripshift instead of trigger and the next level up Sunrace cassette. I have the same frame (2013) and I am planning to do a video in Spanish. Hopefully it turns out as good as yours. Thanks for the video...

Woah I love that chain whip

Helped out a lot thanks mate

Using the Sunrace 42-11 10 speed on a xt budget build, 2 years no problem! When upgrading I'll still go for the sunrace products.

Nice bike behind at 8:40 ! The main difference is the weight of the cassette, GX has ~450gr.

I just ordered the eagle 12 speed kit, gx shifter, gx derailleur, gx chain and the NX 12 speed cassette 11-50 which fits my Shimano driver hub, this kit is going on my 2019 Rocky Mountain Blizzard 20 fatbike, I can't wait for it to come in! Great video!

Thank you guys!

I love my GX 12-speed setup

Cool video. My only gripe is that such a light build received such a heavy cassette. But whatevs. Still fun and informative. Thank you.

Cool bike !

Great video. I thought I would have to upgrade my rear wheel to SRAM XD to go 1x12 until coming across your video and the Sunrace cassette. Many thanks

very interesting!

Nice job

wow that's actually genius

Im a GX user also but i also used XX1 cranks

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.

Muito top essa bike!

Well done sir thank you

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

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.

Been there, done that, it works great... 👌🏽, currently using the 12speed sunrace cassette, sram gx shifter and shimano 11speed derailleur...??? 🤯, yes I'll repeat it, shimano 11speed derailleur and it shifts smooth like butter...😁👌🏽

EXCELLENT video and great information! Thank you! Unless I didn't notice it you did NOT change the chain ring to a 12 speed? The 12 speed chain will work ok with the 10 speed chain ring? Thank you.

I feel like he's my dad too since he talks about him to us as just "dad" instead of "my dad"

I assume the bike was a 2 x 10 before? I'd like to know what you did to the front to accommodate the 1 x.

Well done! Now you can climb a wall

Dank I already put the nx eagle cassette on I could of used this one.

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

I like it bro

It is compatible with my shimano non series bolt type hub?

Great Video. advise please ; i currently have Cassette Shimano HG50, 11-36, 10 speed, and wanting to upgrade to SRAM GX1 x 12 Eagle Drivechain will this work or not if not what would you sugest

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.

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...

Great video, made the changes with 12 speed gx Derailer shifter and chain, Sunrace CSMZ90 cassette. Can’t get the derailer to shift into the largest cog, any ideas?

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.

Cycling love 💞💞

Just did the same conversion. and everything is working great except the shift from 46 to 37 that just wont go. not sure why only this gear.

Cool upgrades!Can i put 1×9 transmision on a cube analog?Ride safe !

SRAM NX 12spd Cassette is what I use on my Kickr which is a Shimano freehub

I have a 3x9 27.5" XC bike with a 11-34T 9speed Cassette ("CS-HG300-9")... I`m planning to upgrade it to a 1x12 drivetrain... Do you think the Sunrace cassette will work on my hub?

Nice video, thank you, I have a 3x9 Shimano XT right now and would like to swap to a sunrace CSMZ91 12speeds cassettes, I won't need to change the freehub?

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 ??

Great video! Do I understand correctly that the gx 1x12 fits a Shimano 8/9/10 hub? I have a formula dc22 hub with a 2x8 drivetrain that I’d like to make 1x12.

Brother, nice video. I have an Epic Comb 2012 with X5 (front ) and X9 ( rear), do you think I can do this upgrade you just showed us in the video?

You could have used an nx or sx eagle cassette because they use the standard shimano driver and not the xd but still a great way to get around your problem

I got the SRAM NX 12 speed but its a but too large for my Shimano 135mm hub. It comes out flush with my lock nut which means the 11 tooth is a 1-2mm from my frame. Will this produce the same result? Or will it fit a 135mm hub?

Are you happy with this conversion? How is it riding? I am considering this with my 3×8 TREK 2012 Gary Fisher Yahoo. I love the bike, but hate the front finicky/detracting 3x gear derailer.

So this works on any hub with a Shimano free hub?

Hi just came across your sram 12s conversion (Shimano Hub) I’ve just only converted my Focus HT ebike from 9s to 10s using Shimano Linkglide system….Wow what a difference…. however I’m a sucker for the new electronic sram asx etap shifter/derailleur and need to know if can I fit the 12s cassette onto DT Swiss wheel 10s 3paw hub or do I require a new 12s hub ? Furthermore will I need to replace my 34T chain ring and cranks ? My ebike Focus Jarifa2 appears to have sufficient clearance for chain movement to large cog at rear !

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.

Shimano 9/10/11 is all the same hub. I put a sunrace 11speed cassette on a hub body that had a 9 speed cassette on it over summer. I would have put on the 12 speed but it wasnt out then.

Thank’s !

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?

hey man you said CSMX80 EA5 its only 11 speed or do you mean CSMZ91 WT5? CSMZ90 WA5?can you double check?

Do you have issues with backpedaling in the 50 cog?

If any given bike comes with an Eagle drive train, does that mean a Shimano cassette would not fit on the rear freehub?

SRAM eagle sx runs a Shimano freehub anyway, I think nx does as well, I know as I just changed my wheelset 👍

Would 12 spd cogs fit for 135mm freehub? Or should i replace for 142?

Hi does the chain drops down the sprocket when u back pedal?

Did u have to change the hub....im looking at doing this but my current hub is an 8 speed

@Jordan Sands was this a Shimano FH-TX505 rear hub?

Hey, do you remember what dimension you have on that hub? 35mm?

Can i fit 12 speed caseet on 9 speed hub idk?

Was this done on a 10 speed hub body or an 11 speed hub body? Thanks!

you could put nx casette and have gx shifter thats how im running and works flawless on my canyon grand canyon 7

What hub do I need for a 12 speed?

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.

Nice conversion Jordan. Don’t listen to the torque dorks and weight weinies.

I got a 21 speed multitask bike do this work on it I want to upgrade

Great video! Was trying to figure out the XD Free Body conversion, you skipped it. Did it workout ok in the long run?🙄

New sub

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

I really want use ur setup but maybe from a 3X8 to a 3X12 just to get up 30to maybe 45 ish degree inclines on my city's park so thank you

How do you insure it fits in the frame

This good in RB so fast speed

Next video. Puting 12 speeds on the front

What’s the weight difference from the old components?

Hi there I wanna make my own bike for cheap but wanna go for a SRAM but I won a mtb bicycle with a 135mm spacing would a 12 speed sram SX, NX or GX work with a wheel which says 11 speed?

I thought a 10 speed cassette was large omg 😂

Hello can I have the old cassette ? 🙂

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.

i have a 3x9 setup, will this sunrace fit?

Estan muy buenas esa velocidades yo quiero unas de esa cuanto sera su precio

Will this cassette fit a shimano 10 spd HG hub??
