Fantastic video thank you for sharing
Tip of the day! a 50p coin is good for holding the back bolt slot while you tighten the from nuts .
wow, You did this in 2014 ...amazing, like like like
@@LoveMTB most of narrow wide chainring are 4mm width, while gears on 3x systems are 2mm width. So we can use the same bolts from 3x systems, when converting to 1 by.
I just bought myself the Race Face Narrow/Wide and installed on my existing arms also, I got the lime green, looks amazing.
Yes it does...
Hey LoveMTB, I converted my nonboost Scott Spark (2016) frame XT 2x10 to an 1x10 with m6000 rear derailleur with 11-42 Deore cassette in combination with XT shifter, XT FC-M8100 crank, AbsoluteBlack oval chainring (34T) and SLX 12x chain. The performance is outstanding. I tested the setup sufficiently in a hard endurolike MTB marathon race. Thanks for your support... 🙏🚴👌🏻
60 seconds on the grinder and I made my chainring bolts the right length for a single ring.
Good one, cheers
You also saved the weight for you front derailleur, cables and the shifter! :)
+LoveMTB XD Less weight can't hurt bro ;)
Excellent explanation of the parts and the presentation of the video. Thanks for sharing.
The chainring shims give it a cleaner look if you aren’t using a bash guard.
Great!
Thank you!
I have been looking for this information as I did not know why the chainring has that shim, or whatever the name is.
Cheers! :D
Cool, I bet it looks sweet on the bike. you should have put it on man. Thanks
I put plumbers tape on those chainring bolts, keeps them from making any noise..
you actually saved MORE then that wt-wise. rotating mass is triple its static wt felt resistance.
It is indeed useful! Thanks for sharing this idea👍👌🤙
Nail Varnish excellent thread lock
@@LoveMTB Yes I can ,been using it for 40 years ,even the clear laquer is better than loctite blue/red.
Fantastic details, thanks for posting.
Thanks, dude. Awesome video!
300grams plus front derailleur plus shifter, so you saved about 500grams?
That's great, tomorrow I am going too for 1x9 11/32, in near future 11/36
decathlon has a neat cassete with 11-42 range, dirt cheap for 9speed, you can buy it for like 15-20 euro, just discovered it a month ago!
I need help, what would happen if you just left middle chainring... would that work? My middle has 32t and that is just what i want so I dont want to buy anything else... pls help
I’m converting my bike to a 1x10 all of the parts should be here Saturday, I got an 11-42 tooth Sun-race cassette and a 30 tooth raceface chainring
@LoveMTB do you have Instagram I’ll send you a pic in a couple days when I’m done
@LoveMTB I followed you on both my accounts @okaloosa.bike.club and @sam.huml
how'd the 30T go? I've ordered one but bit nervous,wondering if I should've got a 32
Great videos Mevnet!!
Very detailed, thank you!
Thanks man, this helped a lot
Tşkler güzel çalışma
Thanks for this informative video!!!
Hey I need some help
I have a 2018 rockhopper comp and it has a stout 3x9 i only use the 2nd chainring in the front and was wondering if i can just take the two rings off And still use my same cranks and everything ..cant spend money on new cranks at the moment
Thanks would this work for my 2019 Marlin 7 with the shamano 3x9 system?
Hi, can I just use the stock middle chain ring instead of buying a new chainring? Do I just have to buy shorter bolts and just remove the smaller and bigger chainring? Thank you in advance
+LoveMTB thanks man!
Did it worked fine?
When the chain ring wears after normal use does the chain slips?
quick question, so if i convert my 3x to a 1x and buy the exact same race face chain ring, i will NOT need to buy single chain ring bolts? I can use my existing?
Thanks man, I ended up buying single chain ring bolts.
Hi really nice video!, i need help, ive got a 2017 trinx x7 elite and i have a 2x10 setup with a prowheel crank, my problem is can i change my 2x crank to single 38T crank?
I'm looking to upgrade my 3x10 to 1x10. I have a 11-36t shimano cassete, cranks are fc m612. Is 34t oval too big for the uphill? I'm scared that I don't spinout while going fast. Do you know any chainrings that would work for my crankset?
I was looking for this! Someone showing that there's space for the chain. Do you know if is enough of a space for a bmx chain?
Do you need to change the size of the bottom bracket in order to do this conversion?
May i know the length of the square tapered bottom bracket that you are using?
My current 3X7 feels like the chain is gonna drop out when i use front gear 2 and back gear 7 (largest cog) was pretty worried that when i convert to 1X10 my chain will drop off immediately.
My planned setup is;
1) Shimano Zee FR 10 speed rear deraileur and shifter
2) Shimano UN26 113mm Square Tapered Bottom Bracket
3) DECKAS 34T round chain ring (not sure is oval a better choice though)
4) Shimano HG62 10 speed fly wheel
5) Shimano m475 rear hub
6) KMC 10 Speed Chain
+Kew Madara A rear derailleur with a clutch will reduce the amount the chain bounces around and potentially coming off the front chainring.

Hello, good video. I want to change the 3X10 to 2X10 in my bike. It has a SRAM S-1000 3X crankset, SRAM X7 front derailleur, SRAM X7 shifters. ¿Do you know if I need to change front derailleur and the left shifter or just the crankset? Thanks.
Thank you very much
thanks very usefull info there
I’m building a jump bike and it’s a 2X10 should I make it a 1X10
Freddie Cowling I would change it to 10 X 1
Great vdo
Thanks.
hello i have the same setup 1x10 30t chainring and i am about to install a 11-36t cassette in the rear just like you did. How do you like the gearing for climbing up steep hills? also is it fast enough on the straights?
you can get a 11-42 tooth casseste
@@shaanrakhra5483 I have a 435 gram 11-42t cassette right now with a 30t chainring. I was wanting something significantly lighter. Seems like the only option I have is to go 11-36t with a 28t chainring?
So if I convert to 1x I'm supposed to keep the middle chainring or the smallest
Why does everyone who does also buy a new chainring.. Couldn't you just keep the middle one and remove the other two?
its not made to be equipped alone, its designed so that any wobble makes the chain move so you need a proper one thats designed to not fall
Great video! Quick question - do/did you have a problem with the chainline when doing this conversion?
why guys greetings from brazil
can you use the original 30t chain ring
Yea
+ewelina kryszczyszyn you might want to change to a new chain ring for a better ratio saved weight and it will run smoother if your old chainring is worn
you could but it would be terrible, chain would be dropping all the time. the original is designed with angled edges on the teeth to aid in shifting, also the teeth are shorter, does not hold on to the chain well.
a single may be better but if the original chainring worked okay in a 3 ring setup I dont think it would be all that terrible in a 1 ring setup - I dont see why it would drop all the time.
you surely can. i've done 1x and ss systems in tones of cheap bikes and they always work. if it slips, probably just need to remove 1 chain link and try again.
Hi sir I have a question.. What if your crankset is 3x but the chainring is not removable?.. What will you do? Tnx?
@@LoveMTB ok thanks
I have a square tapper 100mm. You think i can use the same crank arms? Is 2x9
Because my plan was to change the crankset and bottom bracket for external bottom bracket, but I don’t think i can get crankset with a long spindle
what brand is that crank arm and how do i get one so i can convert thanks
It doesn't have to be the same crank arm, it just has to have the same sized bolts, which most do. Just check what yours are now, they might well be fine
Hi dude! I wana put 32 NW raceface on my spider from Sram s1000. Only one thing i am not sure that there is same chamfer on the chainring which allow to chain feet proper. Do you know how to ensure it?
i have 104 on s1000
You right it is old series 104. Do you think (www.chainreactioncycles.com/race-face-narrow-wide-single-chainring/rp-prod109723) will fit without spacers?
I will try, appeciate your support!
Could you put a link to where you got the Lasco 152mm crankset?
+LoveMTB Thanks. I've got everything except the crankset. For some reason I thought you reused the old crank. FYI-The MEC ACE 24 has this Lasco crank. But it was a 7spd hub. It was either change the hub or change the crank. Not sure which was the lesser of two evils. But i went the Ghost Powerkid 24 route.
+LoveMTB I can't seem to determine if the SR Suntour XCT 414 152mm is a crank that i can remove the chainrings or not. I can't find anything confirming yes or no from Suntour. Would you know?
+LoveMTB I saw that too. I wanted to be sure, because not everything on the internet is right! And I tried calling these online shops but they don't even have the part there, it's at the warehouse. But I got my answer from SR Suntour. I called them directly.
The XCT T312 is on their site and for anyone else wanting to do this build for their kid. You can buy directly from SRSuntourna.com and click on shop.
the XCT T312 comes in the 152mm and 104 BCD. As for the chainrings, the middle and inner chainring are riveted together. The outer and middle are bolted. So you can remove outer and have it as a double, or your can remove the middle+inner chainrings and get your 1x crank.
So ordered the XCT T312 in a 152mm. Can't wait! I have everything else complete.
What if my crank arm is welded on the crank set
You'll need a new crankset...and possibly a new bottom bracket
@@mynameishaydn3287 yeah I bought them last week
Will this work on my sr sontour 2 by ?
Is it better to convert an existing 3x crankset or get a new set of arms to attach to the chainring?
I’m asking because a used Shimano Alivio 3x can be cheaper than a new arm set.
Great, thanks for all the help. Will be converting my Mongoose Vinson to a 1x from the existing Alivio SRAM gearset using the 30t Snail ring.
chainline varies a few mm, so the chain may be more crossed if you use a 3x crankset, but it can be solved with spacers in the bolts too!
Where did you buy the Lasco crankset?
Thanks! That's what I figured.
Just FYI, I have found a new source of some custom made Lasco cranksets with 2 ring setup and bashguard.

Good fideo
So what gear you using on the back ? 18T ?
Ohhh sorry i thought you had only one gear on the back & how do i calculate the gear ratio ? Thanks
Should I turn my Bike in a 1×10? I have 2×10.
@@LoveMTB I ride a Specialized Stumpjumper, I hate it when the chain falls off the chainring when I speeding up... I would be fine with the gear range...
@@LoveMTB do you have Instagram?
Can you use just the middle chainring taking the others off ?
since noone else will tell you , yes mate you can, currently I have taken off jsut the top ring and left my 1st and 2nd rings on as I like the smallest one and you dont really see it behind the 32
@@Millzieeeee thanks for that 👍
@@dazzasp3 listen though , if you have a 3x and take off the largest ring please remember don't try to shift higher than the middle ring it's an instant chain drop , will be a learned behaviour I suppose
@@Millzieeeee never use the top ring 👍
@@dazzasp3 perfecto
I did same thing. and after a few rides there is now annoying chain chatter. basically the chain is sliding and contacting the spider as it spins
What is the purpose of this? A single will have more chain misalignment than a double or triple chainring properly shifted. Is the point to easily get progressive gears? I currently have a triple x 7 (21 speed) and I only use the largest 2 cogs with the granny chainring, cogs 2 thru 7 with the middle chainring, and only the smallest cog with the largest chainring so that gives me 9 speeds. In order they are (1,1), (1,2), (2,2), (2,3), (2,4), (2,5), (2,6), (2,7), (3,7). Notice that I never have to change more than 1 gear (either front or rear) as I sequentially shift thru the gears. No double shifting is required. This simplifies things. Also, since I use (2,4) most of the time, the chain is in near perfect alignment cuz those are both the middle gears with a 1:1.7 gear ratio (34 tooth front and 20 tooth rear).
***** You bring up a good point too. Kids are kinda dumb so making it just a simple 1-7 single shifter is something their simple minds can better comprehend (but why wouldn't they just buy a 7 speed bike in the first place)?. However for adults like me, I prefer the added challenge, flexibility, and range of a 3x7 setup. Actually I am contemplating upgrading to a 3x9 setup so I can use 3 cogs for each chainring (still a 9 speed) but with more range (lower low and higher high). I wonder with a cassette system if the rear cogs have to be sloped as they currently are or if they can alter pattern such as 35,28,22,25,20,16,18,14,10. The idea here it to help keep the chain better aligned. The front chainrings can be selected so that there is a progression of the gears (For example, 3rd gear (20/22) can then go to 4th gear (30/25). I've never seen a cassette where the cogs are anything but sloped (large to small). The front chainrings would be 20/30/40, giving a range of 2x. The rear would have a range of 3.5x. Total range of gears is then 7x (from 0.57 to 4.00). If anyone has tried something like this please let me know if it works cuz I may try it too. The drawback here is if you forget to double shift from 3rd to 4th you can accidentally effectively downshift from 20/22 to a lower gear 20/25 instead of upshift to 30/25, even though your gear indicator may show 4 after the shift.
***** As far as a single saving weight over a triple, it is negligible. Just take some french fries and soft drinks away from those kids and that will make more of a difference than the conversion to a single.
+David James converting a triple to a single sheds quite a bit of weight. 1-2lbs. so i wouldn't say it's negligible. Those steel chainrings aren't light when compared to the 30t N-W from RaceFace.
the logic behind going 1x vs 3x is that with any multiple front chainring setup there's going to be overlap. For ex. in a 3x7 setup you won't get 21 unique gears. There will be overlap. Going 1x7 means you lose upper and lower gears.
But going 1x10 (and i'm using 10sp because 8,9&10sp use the same rear hub) you can retain most of the gear ratios from a 3x7, 3x8 or 3x9 setup, and benefit from the weight savings as well as only having to think about shifting the rear derailleur only. And i don't know how many times i've dropped a chain from my front chainring shifting to the smallest ring. A 1x pretty much eliminates that.
Ray G I disagree that all 3x7s, all 3x8s, and all 3x9s have gear ratio overlap. They can be designed so that doesn't happen. Also who cares about 1 or 2 pounds on a bike? That is negligible compared to the entire weight of the rider+bike.Even 2 pounds is only about 1% of the total weight. If you add 30 pounds to a 3000 pound car will you even notice a difference? That would be like adding 4 gallons of gas and going for a ride and telling me you can actually notice that.
+David James For me it's a simple case of I never used the big or granny ring on my 3x10, so they may as well be removed. No shifter, no mech, less cables and 2 less rings = weight saving, cleaner looks and less maintenance.
Can't be fast
Its for a child, thats why its so small
