Back again with another action packed Explained video for ya. This time around I'm discussing all things sprockets. From gear ratio to material to bore size...I do my best to breakdown what you should be looking for when buying a sprocket. Then, I run through 15 or so sprockets from various companies thanks to Source BMX.
Check out the massive stock of sprockets (and everything else) that Source BMX carries:

Getting back into bmx after like 16 years man things have changed
I’m back into the life after 14years...
And yeah man, things definitely have changed 🤣
Yeah i almost died on my new street tech geometry bike lmao grew up riding trail geometry bikes.
I'm with you guys. Started riding in 88... Lol
Same boat with you fellas late 80s saw Crew walk Hell Track and I was all in. The first time I rode a 9 tooth rear sprocket double wall rim with a fatty 100 psi tire blew me away. I felt forced into mountain bikes never really liked ‘em . a 20inch bmx with 44 16 gears you couldn’t keep up and as you put on weight as you get older just felt unsafe. Today I ride a 20 inch 36 9 gears with 155 crank arms “ mama look I’m ok with my short legs and husky build😂 I used to hate it when I was called husky in the 80s now I’m like this grown ass earned man body son. Gen x we’re the greatest generation now. Always the coolest. I can’t wait for Lori to get out of prison so we can go ass sliding
Same here lol. What happened to the 44t??
Great vid, love nerding out on all the specs! Really like the lighting as well. Any plans for a follow up to the "how a bmx video part is made"? really enjoyed seeing all the tech and planning that goes into your edits. cheers.
I’m on team 28/9 let’s get it
What I've ran for years now, a 28t shadow lashaan kobza cobra sprocket that I've had for years now
Over 20 years of riding, here are some of the most iconic sprockets I remember having.
44t DK Iron Cross - The first nice sprocket I ever bought, it went on my DK Legend back in my race days.
44t Profile Whippet - One of the sharpest and most iconic looking sprockets in BMX history, Golden days!
44t Sharp Hardcore - Remember that 420 chain wearing holes in your seat stay? Street Cred! My Kink Emprire Revision B probably weighed in over 30lbs at this point.
30t Tree OG - A revolutionary sprocket at the time. Extremely durable, light, classic looking. Probably my favorite in terms of practicality but it also had a really classic look that I still love.
25t Profile Spline Drive - Another huge evolution was the spline drive sprocket. Aesthetically it reminds me of my Tree sprocket, but it's much more refined like the Whippet. In my opinion it's the most beautiful sprocket I've ever seen. I'd rather have the 30t, which Profile makes, but I got the 25 to match the driver on my hub which only came in 9t.
Love geeking out to these videos man. Big fan
Started 44/16
Graduated on 28/11
Now on 10s 30x11-42T
I went with the Begin sprocket, thats what my local shop had on the shelf, I'm pretty happy with it so far
As usual, homie, very much appreciate the time and effort you put into these tech vids. It's worth mentioning, though, that multiple sprocket bolt positions is very desirable, even if you don't bash your sprocket or use a guard, as the bolt hole wears and gets bigger over time. I remember being broke and sweating my un...tightenable...? sprocket, until I realized that I could just switch to another hole and start fresh. It was a solid disc, w/no machining, so I even ended up drilling a couple extra holes myself. That bad boy held out for YEARS until the teeth ground down and shark-toothed. Cheers, love and respect!
Totally true. Forgot to mention that! Thanks foe the kind words and the constructive addition! 🙌
most of the street riders I see end up with la guardia, I fell in love with the knox v1 when I got it on sale
Chingon .saludos desde Tonalá Jalisco México
Got my profile 29 tooth an man i love it 29/8 gear is the best for flow in my opinion!
primo sprocket bolts are called "chain ring bolts". old sckool 2 pice bmx and road bike use them.
Got the Profile Galaxy 28t blinging our my S&M ATF 😍
Great insight.
This video made me realize that I don’t have a sprocket for my profile cranks that I just bought
43/16 was the hot race setup back in the day. I see how these give better ground clearance for tricks.
Yea I ran a 44 16 for everything. 28 9 is close to it I feel
The primo omigauard is the best! (IN MY OPINION) I run the 26t black on black. Ourbmx totally forgot to mention how cheap it was. I can't remember off the top of my head but it was around 45$! That's its. Win win, primo is tight af!⚔
Its 42$ lol
FBM 28T Supernaut natural looks like a cragar, rader, or American ribbed spoke wheel. On my Sunday 3rd wave. TLC Bikes 25T vintage oilslick. Looks like a vintage Porsche 911 alloy wheel. On my sons Colony Inception. I like sprockets that look like vintage wheels.
They look like beyblades. Haha. I run a solid 28t sprocket btw. Informative video tho double thumbs up.
Remember the days when bikes came standard with 44-16 :) The fusion sprocket on my Haro Sport and some of the Dragonfly and Hoffman bikes. First time I rode 25-9 was when I was sponsored by Specialized and got both (!!) a couple Fuse 4 & separate S-works frame in grey metallic. Really miss those days.. 🚲
This sproket very high quality and good eye chatting
My two favorite sprockets were the Threshold 46t with bash guard and the poverty penny 45t. My son has my poverty penny hanging on his wall with broken teeth or I'd put it back on my bike
I was gonna say I don't understand how rotating a sprocket gives you more life for sprocket grinds cause it rotates with your cranks, then I relise "Ooo yeah the cranks get in the way so you can only do grinds when your cranks are level so it only wears down two spots" made me feel dumb af and I mess with bikes all the time 🤣
it would be nice to know the weights for both the 25 and 28t
36/9 setup for my BMX cause my friends mostly are using RB. Avg running 40-50 kph.
Very good video A.K.A. niiiiiiiiiiice
I remember my first grind disk, 44 tooth khe aluminum beast.
Don’t forget the Sunday Sabretooth V2
Do an episode about pegs. I know it sounds like a simple part but there are a bunch of things to consider when buying pegs. It wasn't as simple as I thought it would be.
Will do!
Hope this isn't a stupid question, but which chain should I run if I want to run the 30T Profile Galaxy spline chainring with a rear cassette. Not sure yet, but maybe something like a 8-10s cassette in the rear. Shimano or Microsift setup. I'm asking because I would want to run the 165mm BMX crank upfront with threated BB into normal hardtail mountain bike frame, want to create a half bread. Half pump track, half bike park kinda machine. Would still need to figure out the chain-line etc.
Ive got a profile blackjack 36t sprocket,pretty much need a dirtbike chain with it. It is indestructible.Literary.
Ever since I got a Tree Light I won't run anything else. Crazy strong. Only one with the I beam design and it's 5/16 thick.
I prefer the old profile logo style sprocket. 23t anadized purple was sexy af! But wore out pretty quick
If you like the profile galaxy, you’ll like the madera helm sd. Also made by profile
What’s a good sprocket ratio on a 27.5 big bmx
My 6061 6mm sprocket is all wongo Chongo now it just doesn't look like it spins true and it's only like 5 months old I'll definitely be looking for a thicc 7075 sprocket now
Have a revenge/s&m budsaw sprocket (pot leaf) Rasta style color wise. I miss 36t sprockets but there's not a 13 tooth driver for a free coaster
I can never find the parts I need from source in the us and I love them. Most of the time I have to go with oriol bikes
Yep. They don’t even need to ad, just to have shit in stock more.
On god though. An since covid no fucking parts man.
Empire
There’s definitely a massive shortage of parts since covid. I went to odyssey a month or so back and it was a wasteland. They didn’t have a single pair of pedals in the entire place. 🤯
And we always recommend to support your local shop if you have one. 🙌🙌
If I wanted a 9t hub on back can I go 23size sprocket on the front 🤔
Great work Jeff Z, like always 👌
That’s not Jeff. 🤣
That’s Stew Johnson , he makes videos
He's Ryan Fudger, i changed the name jaja
Hey nice
Is it okay to use 44/22?
First 25 tooth I had was on an Eastern Jane
30/9 FTW
What about shadow and colony sprockets?
What name of your sprocket bro? I can buy it what brand?
I thought it was La Guardia at first too. Don't sweat it.
I’m currently waiting for my frost blue Sunday Knox V2
U still waiting?
28t 9t seems to be the best overall for me but I understand how someone could need a 25 in tight spaces.
I have a 12.1 backend on my medieval, and im worried about a 26t fitting
@@ArmyBoiSweat shit dude thats tight haha
basically the driver teeth amount divided by the amount of teeth on your sprocket will give you how many revolution the wheel will rotate on one crank rotation.
25/9=2.777
28/9=3.111
30/9=3.333
I ran a 28t 9t for all round riding its the best for jumping gaps, random dirt jumps without run ups, random quarters with open area run ups to gain momentum is much easier than running 25t 9t which looks like hamster riding a bike but works for beginners for grinding. good to know what's ratio works for your riding discipline. started on 44/16, 36/14, 30/11, 30/10 and finally 28/9 king of ratio's
@A H i road with Dirt Monster 2.10 front and animal rear 2.10. but now i roll fly rubens 2.35 front and rear for all round. never change the tire setup since 2.35 came out.
Over the years ive gone from 45/16 then 36/13 then 23/8 then/25/9 and im running 2.25 tyres
Socket drive sprockets ?
I ride 27 x 9 but my next sproket will be a 28t.
our sprockets xaxaxaxa
Why do some sprockets come with thicker/wider teeth to accompany half link chains but the drivers are always thin?! Etc. on free coaster-cassette ??
How is a 39t/16t ?
🙏
I am certainly happy none of my customers have asked me to machine a sprocket with half teeth
Hello, my son is 5 (big for his age,) and has started riding the pomp track. I bought him an Specialized RipRock bmx 20”. It is not the lightest but working on it. Right now the freewheel is 18t and the sprocket is a 40t. Going to replace the sprocket to save weight and mostly, so he can have a little more power. I am thinking to replace the sprocket with a 20t. What do you think?
If you're going 20t front and 18t rear he'll be pedaling really fast to go slow even. That will make it super easy to pedal but will have no speed.
Question, i bought bmx for my kid to cycling every evening for fun. It is 44t front and 18t rear. My kid said quite heavy to paddle at start. So im thinking to change the sprocket size. What size of sprocket and cassette should i go for so that easier for my kid to paddle better and faster at start?
Are you sure it’s a 18t? It should be 16. A 39 tooth sprocket will make it easier, but if you have a local shop, I suggest taking it there. 44/16 means the bike is pretty old and could use an update, if you have the cash.
@@OurBMX Sorry my bad, yah its 16t rear, i just double check it. Ok, so 39t for sprocket, rear just leave it 16t?
How about the size you mentioned that now a day bmx usually comes with 25t+9t, is it much much easier for kid to paddle? Is it possible i go for 25t+9t?
Well actually the bmx i just bought it last year. First sorry im quite noob in this, the shop guy told me its 2020 model, a bmx race bike type. I bought it because they doesnt have any stock for 18" kid bike. And he said 20" bmx is fine for my kid, so i go for it. And since my kid told me quite heavy to paddle at start so i started to google around until i found your useful video. Then after that im quite suprise why they still selling 44t+16t bmx. Yesterday i noticed my friend's 2 unit bmx that he bought for his kids have smaller sprocket, he bought it back in 2017. Am i got scammed by the shop? Lol.
Hard to say without seeing the bike. Some race-focused bikes still use 44/16 gearing ratio. But to answer your question, if you switch to a 39 tooth, it will make it easier for your kid to pedal, yes. Good luck!
28t/12t?
I run 44 to 16 tooth
Swear to god the la Guardia is indestructible
cool vid, lots of valuable info, but guys that lighting/blur makes it hard to watch
animal is also made in the USA
Oh yea, someone point me in the direction of a spline insert that is 22mm AND will fit the RNC titanium sprocket. The RNC came with a 24mm insert, and the sprocket is marketed to use the profile insert design. But the RNC titanium sprocket is thinner than the aluminum ones. So, the Profile insert will not work because it is not thick enough to seat all the way against the RNC sprocket, without damage. And if you did press the profile insert all the way till it seats, then it will be protruding out the other side of the sprocket, instead of sitting flush. I'm at a loss. RNC guy is.......difficult to get a hold of.
I found a wethepeople 26t sprocket and I run 26-9 it's so good
That’s a good combo for sure.
What kind is it, I’ve been tryn to find a 26tooth or 27tooth for so long😭
Edit: with bash guard
@@just1frosty516 Its a wethepeople turmoil sprocket, but it doesn't have a bash guard
Oh aight ty my good sir
@@jasonw7053 thats a 25t
I ride 35/14
I’m tryn find a 26 or 27tooth sprocket with a bash guard... help pls
Maybe the United one is an option.
But if not, search around Sourcebmx.com
I couldn’t find one in source I looked at every sprocket😪, if I ever get to work wit a bmx company ima make a signature sprocket that’s 26tooth with a bash guard
Ahhh, yeah 26/27 is a pretty unpopular size unfortunately.
Why the sudden jump in popularity in sprocket guards ?
Street got more popular
@@ArmyBoiSweat street has always been popular.
only 5 mins in to vid, old school setups were 43/44 to 16/17. when did they become much smaller?
I'm over 30. I believe sprockets went small in the early 2000's
They slowly got small and a smaller over time. When I started riding as a kid in early 2000’s the common ratio was 36/13, then mid 2010 (I think) was around the time that 25t sprockets were coming out. Also the rear hubs went from a freewheel to a 1pc driver that went directly into the hub.
When cassettes came onto the scene and the larger-sized freewheel wasn't necessary anymore.
@@OurBMX True, but they did also make a 13t freewheel for a short time, Odyssey made them, I think. I had one until a could afford a cassette, but yes I did forget that the cassettes had the cogs that you could put on.
@@OurBMX "When cassettes came onto the scene and the larger-sized freewheel wasn't necessary anymore."
They are still considered necessary by most people who run actual BMX bikes. BMX stands for Bicycle Motocross (AKA: Bicycle Moto-X, AKA: Bicycle MX, AKA: BMX), i.e., a bicycle version of the off-road motorcycle _racing_ sport that's called motocross. The traditional sprocket sizes allow for smaller changes to gearing for different tracks (for example, going from 44/16 to 45/16 isn't as big of a jump in gear ratio as going from 25/9 to 26/9 is), and larger sprockets are subject to less stress for a given amount of force applied to the crank arms.
Here's an example of a top BMX racer's bike:
elevnracing.com/connor-fields-win-his-2nd-usa-bmx-1-pro-title-at-usa-bmx-grand-nationals-tulsa-ok/
Notice that it doesn't have a sprocket that's the size of an Oreo cookie.
The bikes on which dainty sprockets are now standard, are offshoots of BMX bikes. The divergence from BMX bikes started in the early/mid '80s. The things that they are designed and used for have nothing to do with motocross.
Seems I have a 40-16...
I have a 60 teeth sprocket with a 12 tooth in the back lol
Heavy to pedal?
I thought the bigger the sprocket the easier it is to pedal well i was wrong
Marketing technique IMHO. Your sprocket still flexes when you pedal hard from the start, meaning wear and tear sets in more if you ride hardcore daily. Smaller sizes really dosen't matter, but with ample amount of pressure each day gives it more probability of cracking or chipping on the metal. I always run 39 or 40T to 16 FC, so if I torque for speed it'll be a speed I can handle, or at least something enough to clear a jump at full adrenaline to make me cautious and think WTF am I doing.
Profile forever.
How would 28 8 feel ? Lol
Tough.
I would imagine its like 32-9
