Bill, that was one of the best explanations of disc size and modulation I have ever heard. Wonderful job. Racing BMX, road, Cross, and Mountain since the 80s, I now really get the point you are making as Mountain definitely does require modulation ability but also the ability to really stop or slow you down on steep downhills.....not the case with BMX, where it is almost all modulation/maintaining speed. Thanks again for this video.
You are very welcome. Glad we could help
Coming from the MTB world, I love hydraulic disc. And if you taco your rim, you don’t have to worry about the rim rubbing.
Totally make sense in MTB bigger wheels, Knobby tires, bombing down hills, wet stuff, mud, gunk, rim brakes SUCKED on MTB's... BUT with BMX, the smaller wheel, the controlled environment, the V- brakes offered great modulation and great braking... BUT DISC have arrived, so lets do ti RIGHT!!!
I have just switched over to disc brakes on my RS7 cruiser, this video is food for thought, thank you 🙏
Glad it helped! Thank you for watching!!
Another great update! Same holds true for big bmx bikes. I want to feather the brake and keep the wheel up on a wheelie. Makes sense to use a smaller rotor.
Thanks! It does! Got to be able to feather when you need it! Anti Lock Brakes exist for a reason!!
God Bless you..Bmx is super..
Good stuff! I figured smaller rotors would make more sense for BMX back when I first saw the disc brakes showing up... Don't need the same braking on the track like I need for a long DH run...
Right on! You don't need the same braking. Different bikes, different forces. Use what you should use. Not what you want to use.
Good video and true. 120 is plenty, a 140 is almost too much and a 160 which I had and what your OS20 comes with is entirely excessive. Instant lock up and great for high siding just like you've mentioned in a podcast. Good for getting bent too in crashes. Admittedly perplexed by the decision to use a post mount and 160 on that OS20 frame. I had a custom Ti frame made with the same set up and will never spec a post or 160 again. I like hydraulic for sure, but a good cable disc is plenty for bmx. Good video!
120 is more than enough. The OS20 frame was designed 4 years ago and was based off of the Shine D/J rear set up for disc… and for the BIGGER guys on it, the BIGGER wheels, and running a cable activated , it works super good!
@@SupercrossBMX. ah, that makes sense being a 160mm and cable. Hydraulic is way too much with a 160 rotor. Buddy went cable on this same setup and loves it. Definitely prefer flat mount versus post. Excellent
Wonder how the size applies to 24” cruiser size wheels
You’re getting good at the tech tip Tuesday videos 😬
I’m trying to catch up to you! But I know I will never be as good as the master Kj! Did you watch the burnout at the end?
We still like you KJ
@@Jackbaker99 We LOVE Kj!!!
The new Vision RSX is awesome! Would love to see a detail video on it. And with the flip chip it’s so nice. Perfect for disc like these!
One is coming! I am glad you like it!
Need an honest opinion, I am 43 and will be purchasing my 1st race bike to get started. Both my kids discovered BMX on youtube so this is where we are headed now 😄. So I am between the mongoose title elite and the redline proline for the bike. The goose has V brakes and redline is disc. Priced fairly equal. But you addressed my exact concern about disc on BMX, I am thinking safer bet is V brakes on the goose to get acclimated to racing. But am I going to regret not going with factory disc right off the bat?
First! Welcome back to the sport! But either will be a great entry level bike for you, look for which has the best components as you will most likely be transferring those over to a different chassis as you continue to enjoy the sport!
@@SupercrossBMX. Thanks!! I think I've decided on the Mongoose, i won't need disc stopping power and it has a tapered head tube!
Thank you, Bill, you nailed it with the portion of proper brake set up being the key to using disc brakes on a BMX. I run disc because I want all my bikes to feel the same (BMX, MTB, and Road). Also, bending a rim crashing in one moto doesn't mean you're out of the next moto been saved by this a few times. Disc has always been easier (for me) to set up too. Trying to get toe in on the pads right and everything in the right plane with rim brakes has always been a hassle. Maybe a video on proper disc brake set up for next Tech Tuesday? Considering Supercross mostly sells frames and parts I think your clientele leans towards the mechanically competent (or at least mechanically curious). 48K people watched KJ shove dirt around his yard, watching you set up disc brakes while drinking Rancho Luna might break the internet.
If I set up brakes while drinking @ranchodelunamezcal I know I would break the internet! 😂 no , seriously we have a lot of great stuff planned, and we listen to everyone’s comments. And we are trying to get to everyone of them… well maybe not me drinking a bottle of Mezcal while dialing in Disc breaks…. But you get the idea. But thank you for the comment… I hope you liked the video… and keep coming back for more of what they torture me with.
@@SupercrossBMX. I had no idea James and Nolan at Donut were BMX guys! A collab with SX and Donut would be amazing. James doing a rider retrospective like he did for Richard Petty or Dale Sr. would be unbelievable. You could do a conversion project on their Miata to haul bikes, tools, then take if for a racing road trip to Grands or something.
@@bryantsutton2915 Yes, we spoke to them a while back about getting them one of our Legend Bike Co. Eddie Fiola Bikes, and then James had his heart attack, and we lost contact. But I think it is fair, they send us their 8 million subscribers for our 8 thousand!! Thats an even trade right??
A follow up video suggestion: adapting your v-brake bike to disc brakes. Not all bikes are designed specifically for discs, which leaves out most racers.
Appreciate the suggestion! And no, not all bikes are designed for Disc, and there are a ton of Adapters out there, our Sister company @Speedlineparts makes one, but with all Disk Brake Adapters, you have to be very careful with how you use and maintain them.
This is a Great Video! 💯💯💪🏾💪🏾
Glad you enjoyed it!
Bill thanks for another great video! Don’t worry, I sub’d a while ago because I wanted to see what was happening. To be honest, Super Cross is setting the bar on content. Keep it up!
Thanks for the sub! I appreciate that! Hope we are keeping you entertained and educated!!
Do y'all have a recommended or preferred Caliper/Rotor setup? Most 2-Piston calipers that ive been able to find only seem to be compatible with 160mm+ rotor options.
You can use any rotor size with the calipers. Most of our riders are running the www.supercrossbmx.com/products/shimano-deore-xt-bl-m8100-br-m8100-disc-brake-and-lever
I may be screwed i have super knobby 80s style race tires and already got majority of the 120 rotor installed and im running high psi
Rotor size depends on riding style and I agree if you're racing bmx then smaller is better. I personally use the 160mm rotor since I converted my bmx to a e-bmx and when you got a 72v 3000w electric motor pushing speeds close to 60mph the 100mm rotor not going to work
If you are on an e-bmx and cruising the streets then you NEED the 160mm rotor. We were specifically speaking about BMX racing.
What about mechanical/cable vs hydraulic disc in BMX?
Great idea!!
They won't always fit though, right?
Afaik you can always go bigger with spacers but mounting a smaller disc requires the initial mount to be set up for it.
BMX IS THE BBBEEESSSTTTTTTT!!!!!
BMX is the BEST!!
I totally agree about single pistons and small rotors being enough, but v-brakes are garbage at stopping. Racing is about feathering yes, but what about practice when someone’s kids eats shit and we need to stop *now*. We should be able to do all our braking with 1 finger and enough brake stroke to not contact the ring finger. Riders can easily learn to uses discs during their manual practice
sometimes you have to go larger if you have interference with caliper and spoke clearance.
That is true. But if you can the smaller is better
👊
I'm running 140mm and I will get 120mm eventually
120 is the way to go!!!
@@SupercrossBMX. do I need a different adapter
Running a dirt jumper for years . Hydro brakes are not what you want . Using the cheaper cable you can modulate easier. Hydro was just for flex back in the day and now they are cheaper everyone is grabbing them . I think they make a 110 unless the discontinued it
I have never seen a 110 rotor. 120 is the smallest I have ever seen as a production item.
@@SupercrossBMX. yup they have them , but you would have to make a smaller adapter for the caliper .
But what if my bike takes 140
They make adapters
I want to run a 5000mm rotor. Gonna shout it from the hillside lol
s 5000mm rotor is HUGE, are you rolling on 200" Wheels?? That is bigger than the 29" Wheelie gang!!
@@SupercrossBMX. yes! Starting a new monster bike sport. You should see the chaining. It's the size of a dime. Got this new tech It's so powerful it's pushing so much power to the wheel it's unreal! Great for desert riding!
@@SupercrossBMX. in all seriousness though what brand/model has a good racing ideal disk brake? There's a few out there nowadays. Thanks
Tons of good ones out there, HOPE, Shimano, TRP, tons to choose from!!
Bmx racers should juat take a page from freestyle bmx and just run no brakes .faster that way
