Please could you let me know What size I need for shimano fcm 391 crank thanks

@@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 ⚙️

Very good 😊

Can you put a link to the stuf you used

@@Sebatron-pr9bv Race Face narrow wide chain ring RNW104X30BLK, Shimano Acera FC-M361 crankset (this is for a square taper bottom bracket)

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.

same

​@@piotr462are you stupid?

😉

Very well

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

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.

Usually yes 😁

actually using a mtb uphill makes you realize how little the front 3 matters

@@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

Its connected with chain line and little with visual

Thanks bro 😉

Yes

That chaining has no offset.

you have to count it with the ratio calculator or read what people use and it will be the best for Ciebie

Yes its all what you need

@@lonerbikes Thank you very much.

its work too on two wheels crank

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

Great 😊

Shimano CX 50 crank set is 46/36, try that

Chain line difference, in 2nd option i use bolts from SNAIL set from aliexpress 😉

@@lonerbikes So it's used to control the chainring offset? And, couldn't you have connected in 2nd option with original bolts?

@@YanikBrown yes, yes you can also use original screws, but the snail set looks better :P

yh u can mate

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.

You can keep the 32T but you must replace the current ring for the narrow wide ring. It will prevent a chain from falling of the ring.

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 use shimano, but all cranks types with 104 BCD, you can fight used good condition and buy new deckas crank wheel 😛

If you make 1x ? Drive you can remove front derailleur because you need use narrow wide crank gear

Try to find on Aliexpress: snail bike chainring bolts

No, you need crank with 104BCD Which is flush with the holes

No, you need some crank with 104BCD, to fit it with crank wheel ( deckas 104BCD)

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.

If course you fucking can, imbecile.

Use a normal chain for 8speed. Dont use singlespeed chain because its bad for chainrings 😝

🙂

Po co taki zabieg?

@@subkarpaty zeby miec naped jednorzedowy modny i popularny obecnie stosowany w nowych rowerach

Just use the two original chainrings. A narrow wide (1x) chainring is designed to not shift lol

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.

it's riveted/non removable

Its Shimano Acera FC-M361

So o just buy the first one DECKAS narrow wide on ali 😃, i dont think so that can be fakes of this on alie 😜

@SanDeep Bisht Um no you will just remove it. You could leave it on and never touch it but I guarantee you will accidentally hit it forgetting that you went to 1x. Just remove front shifter and derailluer and be done with it.

3 gear Crankset is for people who like driving fast

@@ericgonzalez9096 Yes i was used to that before I got new bike with NX sram 11x1 and I was surprised about how slow it was in comparison to a 3by ,, but that's because my old bike was a cheap cross country and my new is a electric trail bike

If this crank is 104BCD - then the DECKAS gear in the video will fit Check that this crank is 104BCD for sure, Because the bcd of the sprocket and the crank must match- facing the holes 😉

it depends on the model of your chainset if you have bolt on chainrings its doable, if not... than

Suntour is garbage, you don't want that crap on your bike

No, but its doesnt matter , Important here is only correct chain line 😉

Very big differences, read something about this 🤓

@@lonerbikes can u create some real comparison video when 2 guys ride 1 & 3 speed for acceleration, speed & uphill, maybe that will interesting 😀

@@Bts-ce4ej 3 speed faster lesser torque, 1 speed slower higher torque

I don’t think you have to I think he just wanted to because I’m going to try this soon

dude, its required to swap chainrings when converting a 3x crankset into 1x because the ones installed in 3x cranksets aren't narrow wide which allows the chain to be transferred to other rings in the crank while a 1x purpose built chain-ring has narrow wide teeth so that your chain wouldn't derail when trailing or going through rough terrain.

Do I have to shorten the chain if I do this and if yes by how much do I have to shorten the chain ?

@@JS-bh3fg it depends if you are willing to change your cassette from a smaller teeth count to a bigger one(ex. from 11-32T converting to 11-40T and higher). If you decide to keep your old cassette(possibly a smaller teeth size),you need to shorten your chain to keep your derailleur in tension. If you change to a bigger cassette size, you don't really need to shorten the chain pretty much. edit: it depends on the size of your cassette and your chainring when choosing the right length of chain. PS: if you have a medium cage derailleur, you either extend it with a goatlink/extender(downside of installing this is not having a smooth feel when shifting up/down) to accommodate a bigger cassette or the jockey rings will collide with the biggest gear of the cassette or...change to a long cage derailleur.

if your chain line allows it I think so narrow wide sprocket in the place of the central table top from the middle or outside depending on the chain line

@@lonerbikes Are you switching just to be fashionable? Unless you’re changing your rear cassette to a modern cassette, you’re going to lack gears on the high and low end. If I were still racing XC, I would never go 1X; just not enough high end gears.

yes

Yep, exacly

Can do by some spacers, no need correct chainline, not backpedaling

@@dienphanvp thanks!

It does not make sense And the chain line will be bad

@@lonerbikes what if we use 3 same size cog to keep chain in line

Great!
