@@benbryan6512 this crank is 104BCD so Correct for the same chainring like one video, but you must the size of chainring choose according to your needs Use RATIO Gear calculator and compare chainring size with casette ⚙️
i did this conversion several months back and its worked out great. no more messing with a front derailleur and i don't feel that i've lost anything in terms of riding performance. i used the middle ring more than 90% of the time anyways on the 3 ring setup.
53T/39T chainring and 11-32T Casette has the same upper and lower gear ratio as 1x 53T chainring and 11-42T Casette. 1x isn't totally losing out on the important gears if you don't mind the less narrow gear shifts.
From what I understand about chainline, the front ring needs to line up with the middle rear cog. So you would use option II and possibly up to 4 mm of spacers and longer chainring screws to line up the chain.
Thank you so much for this video!!!! I unnecessarily took mine apart before I figured out how to take the crank off and it has been a B*** trying to put the three pieces back together. I didn't realize that the outer ring goes OVER the crank but your video helped me figure that out. Thank you again!!!
Been doing this for 10years plus , chainline from middle ring doesn't matter , unless running 12speed where it needs to be bang online in order to reach top and bottom cogs without catching frame
After I got a couple more teeth in the back , I found that I needed the upper and lower ranges less frequently. Eventually I wondered if all the clutter and extra needs of attention was worth it for as often as I needed the outer ranges. I'll still keep the 3x for the road trip bike, but the switch will simplify the commuter.
I like budget 1x conversions and I do it myself sometimes but I feel like the 4 spider doesn't look as great because the way the spoke designs aren't sporty. The DM chain rings look sweeter.
I've done the same but with SRAM narrow wide steel rings which last much longer. The difficulty then is getting them to fit a different BCD. It can be achieved to a good finish with an angle grinder and a drill though.
i did this conversion on two different shimano 3x-Cranks and both times i had to file a bit of the chainring mount on the crank to put the chainring from china (Deckas, Snail, etc. all the same) into the correct position (Pos. option 2 in you video)
The oval crank is an amazing power boost and the weight reduction helps balance the bike out some carbon bars and bars and a billet stem should balance the rest out nicely.
It's so funny how things trend. Those oval rings were big on road bikes in the 80s until some famous competitor said they sucked and everybody stopped using them. Now they are back! lol
Czołem, dzięki za filmik :) Myślę właśnie nad przerobieniem u mnie z 3 na 1 rzędową korbę, tylko pytanko zasadnicze. Mam MTB przód 3 i tył 9 biegów.

First option is bad. Puts the chainring in the same position as the large ring on a triple and creates a huge angle to the chain line when in the big cogs in the rear. You really shouldn’t even show it. You want that single in the same position as the middle ring. Those attachment plates for the outside are slick though. Personally, a single front ring would not have enough gears for me. With modern rear cogsets, you do get the climbing gears, but lack the high speed gears for downhills.
@@gonzalol1754 No you can put it in either position inside the spider or outside the spider. As a rule the middle position will give the best chain line overall.
Really has nothing to do with logo you can run it either way. What he is showing is you can run the chainring in both outside the spider or inside the spider. For most the inside position is usually the best for chain line puts it where the middle ring was. No matter which option you choose you can run logo in or out.
Okay this actually seemed a lot easier than I thought, was out riding today and realized how little I need a 3x so thank you and I will re reference this video once I get a 1x chainring Edit: my cranks are allterra but a similar set up in the front rings will this work?
@@growingup4487 oh absolutely, the park I usually ride to ( a normal park since there’s no bike parks near me) has this massive hill that is super fun to go down but can be a pain to go up and even then I hardly use the biggest and smallest chain rings. I’m almost always using the middle one
My wife just rides on the middle chain ring and as it has 32 teeth, could I not just keep that ring, when converting her bike? I know buying a 34 tooth chain ring would give her a greater power range but I was thinking of keeping the cost down!
Sure. But it depends on if you change the rear cassette. With a modern cassette, you might have equivalent lower gears with the 34 and it might be worth changing. If you want to compare, you can find gear calculators online that will show you what the gear inches are. You just have to input the wheel size and the range for front and rear gears and it’ll show you the numbers for each gear.
The narrow wide single chain ring helps to stop chain drop. The stock chainring with definitely work for street riding but on rough trails and hard riding in lowest and highest cassette gears you may end up with the chain trying to bounce off or “shift off” the stock chain ring.
I have a 21 Speed hybrid, 1-year-old. Could i just reuse the middle ring from the crankset, All I need is the correct fitting fasteners? Then i got a 7 speed.
I'm about to do this on my older 26" full suspension trek fuel 90 with an oval 32T chainring. I have a 3x9 set up. Is it going to really suck climbing hills? I'm thinking about changing the rear cassette but figured I would try it first with the old one on there.
What's the actual benefit of this conversion? I have two chain rings and i use bigger one mostly of the times and small one when climbing steep sandy hills. Works perfectly. I know one ring looks cool and neat but is it actually wort it? As i like to get faster on the tarmac and i like steep climbs too.
Cleaner look, mechanical simplicity, slight weight saving and streamlining of the controls. If your range works for you, it's hard to argue for the expense and hassle.
Hey dude, the 94+96 BCD symetric dekas chain ring can fit to shimano altus FM 361 crank just like yours? i saw u had 104 BCD chain ring to that fit in.
Mostly the con on most setups is outside the spider will cause a pretty bad chain line when in lower gears. Inside the spider which is middle ring position tends to center it better with cassette this will keep the chain line better weather in low or high gears.

Chainring actually belongs behind the spider for the 32t range area to mirror the original position and chainline

Personally, a single front ring would not have enough gears for me. With modern rear cogsets, you do get the climbing gears, but lack the high speed gears for downhills.
I think the large ring is attached to the middle one, so he is installing the ring in the only place possible which is the middle?
@@gonzalol1754 No you can put it in either position inside the spider or outside the spider. As a rule the middle position will give the best chain line overall.
Is the option 2 vs option 1 just preference? Or a lil better performance to it? Thanks for the idea for budget building.
Its connected with chain line and little with visual
Next video do two giant mountain bikes vs each other.
One with the 1x vs 3 x
Problem with this is your chain line in your bigger cog’s will be extremely angled causing more and faster drivetrain wear.
I love option 1 with turning over disc, many brand logo on bike
Really has nothing to do with logo you can run it either way. What he is showing is you can run the chainring in both outside the spider or inside the spider. For most the inside position is usually the best for chain line puts it where the middle ring was. No matter which option you choose you can run logo in or out.
Super helpful ❤❤❤❤❤
Is it possible to use the middle spocket from the stock instead of buying a new one ?
Maybe yes, if the chain line allows but narrow wide spocket is better 😝
bullshit answer, sorry. that will not work at all. your chain will fall off before you even arrive at your hometrails
