[@BUILTLIGHTWOUNDTIGHT]

I pedaled around on a 1986 Redline Proline 800p running around a 19.75" T.T. I had a xxxl goose neck and a crazy tall handlebar. Back then I was totally clueless about sizing a bike for anyone! Then I got a Redline 720xl with Tange blade forks, and the first set of 401 flight cranks in Idaho Falls. I thought this was a major step in the right direction! I still needed a set of 8" tall bars, and the longest gooseneck I could find. And I made it work! My son has this Redline now, but I still was wanting to find a little bit bigger Frame!! So I bought my first 24" cruiser. I bought a 97 Haro group one si with a 22" T.T. and added an 8" tall set of bars and the same xxxl threadless stem I could find. This was a lot of fun! But it still felt a little on the smaller side, but was a monster by weight of compassion to the 800p. Then I found a Mosh 3 star method, and did all the same things. Then one day I decided to Google xxx lbmx frames, and one thing lead to another. And poof the se racing fast ripper was invented, so I decided to take a little closer look. After seeing the top tube at 23.6" I was like o.m.g. this is the ONE!!! After waiting around 3 months for it to show up. I decided to swing by a different bike shop, and sitting outside was the GT PRO PERFORMER in neon orange 🍊 the owner asked if I wanted to take it for a spin? I said nope, because I will want to buy it... So after the fourth month of waiting for the fast ripper, I pedaled back to the bike shop. This time I was thinking about a test ride! And poof my new gt... The main reason for the big gt, is that it has a laid-back seat post and taller bars! Holy Hannah this was awesome!! Then after looking online at the geometry, and seeing that 23.5" top tube. I was like sold, just take my money please!!! I am 6'5" tall with a 36" inseam. My knuckles drag on the floor! I finally have a few bikes that feel like they actually fit me. I don't need a long stem, but do still like riding a taller set of bars! Awesome video man!!! 😎

God I remember when it all started well in England first start to see changes in very late 70es early 80es than it went crazy . I was into race .got a couple Curtis bmxs very old school how different now .just started watching more .it's just amazing now how fare its come so much respect .

[@jcbenson01]

Thank you for taking the time to make these videos. It has been helping me make better sense of some things as I dove down this new rabbit hole of bmx racing :-)

[@SupercrossBMX.]

So glad you liked the video, and the Rabbit Hole of BMX is amazing!!! Enjoy!!

Pedal thickness is something I noticed not many people take into account. I’m not sure about clipless , but there are a ton of flat pedals out there that vary in thickness quite a bit.

[@SupercrossBMX.]

Pedal thickness is a thing, but so is the thickness of the soles of your shoes… pedal thickness really comes into play to keep you from rolling your pedals, more so than bike sizing, but it is always a consideration when we start to fine tune the ride

[@lenBrill1971]

Old school VANS are fairly thin honeycomb gum sole shoes. With a sharp set of thin platforms, rolling a peddal is hard to do. And once you plant your foot, you feel like you're clipped in. I raced from 1986 - 2000. I'm 53 and still "bear" the shin scars of old school super thick bear traps. 😊🇨🇦🤟

[@libertynindependence]

Couple of bolts here, couple of bolts there. 50 bucks here, 60 bucks there, no problem.

[@WaveLordLuis]

Very informative as always. I’m a tall dude at 6’5 and I only ride pro cruisers and I absolutely love em with a 55mm stem. The 60mm stem made me feel like I was gonna flip over my bars 😅

[@SupercrossBMX.]

All about where you feel comfortable! Sounds like you found your sweet spot!

[@TheDjcarlos67]

Nice video Bill. Greetings from 🇬🇧I'm 5ft 10" & had an XXL 450Z but felt a little cramped so I swapped with a friend's XXXL & put 10" bars on it, as I also felt a little hunched over on it. Totally surprised that the extra length & height actually made it easier for me to manual (go figure?) & the tall bars make it easier on my 55 yr old back. No BS this is most perfect bike I've had in over 40 yrs riding BMX, despite it being (on paper) way too big. You really need to experiment with these things 💪

[@SupercrossBMX.]

Glad you liked Carlos! Hope the uk has some great riding going on right now. And a taller bike is setting your back up higher, less pull but more comfort for sure. Again, different people have different needs and different comforts, I am glad you found yours!

[@LemonySnicket-EUC]

I'm 6' and 62 yrs old and I'm going through this same experimental learning curve. I'm wanting a 24 inch wheeled neighborhood cruiser that I can manual on easier. I just want to have fun at 62. I've got nothing to prove.

[@faehimmirza2381]

Just the video I needed

[@SupercrossBMX.]

Glad we could help!

[@1eyedwilli3]

You need my Tange Ultra Strong Supercross from the 90s hanging up there.

[@cyberlingbot3d896]

I'm 5'7" and a pro size fits me perfectly, I did ride a xL for a short time but really hated it, I couldn't get the front end up for manuals or bunny hops as easy.

[@SupercrossBMX.]

Like we said, different riders, different sizes… lots of personal preference…

[@mariocampos2044]

Really? I am 5'6. I use a XL and I had to move the bar a little to the front because I feel I dont fit. For me, it could be good a XXL to feel comfortable.

[@SupercrossBMX.]

@@mariocampos2044 like we said, different sizes for different riders and different styles. You arr 5' 6" and you are thinking you need an XXL and Cyberlingbot is 5' 7" and thought the XL was too long and loves his Pro. Beauty of it is that we have different sizes for different riders. You get that freedom of choice.

[@kimfuger1036]

Thank you!! Great Video!! We would love to have you on Mom's Talk BMX for a "bike size" Talk!!!!

[@SupercrossBMX.]

Email us and we will try to set something up!

[@nomdeguerre13]

Gonna upset the apple cart by going against the old as dirt TT numbers being gospel amongst a certain website.. I have designed 4 frames this past year and a half, was fun watching. Could easily be a half hour and more in depth. Could not imagine a 63mm stem, isn't there an unwritten rule about the front axle being in general alignment with where the bars mount? Anyway, good stuff Bill. 🎉

[@SupercrossBMX.]

Could go hours... fine tuning a Bike is a huge thing. And we have people asking for 70mm Stems at times. A certain Elite World Champion ( Current I must add ) is running our 63mm stem on her bike as it set her up the way she wanted in her rider area.

[@MorleyRH]

I need that shirt! The Black Sabbath one

[@mariocampos2044]

I think they should change the rules. I mean, they should allow the riders to use a size frame of their preference. Same if they want to use "speeds" like "MTB" bikes use. So, you could see races between 20 and 24 or even 26 if they want to.

[@gotmoto]

So what’s deal with some manufacturers randomly listing the rise of the stem in degrees? Most are in mm but some will say 5° or +/-5° etc. I know the +/- is whether it’s mounted conventionally or inverted but not sure why they use degrees instead of mm

[@SupercrossBMX.]

I think some will list degrees as it is one degree for a full run of stems where a 48mm is one measurement up, a 53 another, a 60 another, and it is easy and accurate to list the design dimension.

[@marlonmendes1954]

Legal 👍

[@mikeyseibert1406]

Adding a longer stem to make up for a short frame isn't always good. Putting your bars farther out over your wheel changes steering

[@SupercrossBMX.]

Correct, proper frame sizing is always best, you always want to go with the longest frame, shortest stem combo... unless you want to speed up the steering a bit, then the longer stem will quicken the steering a bit. Too long of a stem causes flop as you PUSH thru the turns.

[@stephen4185]

Can u do a video on your os20 frames?

[@SupercrossBMX.]

Sure, what would you like to see. I thought we had covered the OS20 quite a bit already.

[@stephen4185]

@@SupercrossBMX. can u tell people about the bb height is different and how u have to use different gears to a normal pro bike

[@SuperEddietv]

If you're banging your knees, get a bigger frame. If you cant manual your bike at all and get the front tire off the ground............................🤣

[@mariocampos2044]

nice your Black Sabbath tshirt

You dont strike me as a fan of Black Sabbath but the shirt says otherwise.

[@SupercrossBMX.]

How can you not like Sabbath…. Ozzy… Geezer, …Iommi , Butler…… Faeries wear boots….

[@roberthull959]

Sooo you're willing to send us different sizes to try out and we can return what we dont like? Id like to try one of everything you have

[@SupercrossBMX.]

Hahahaha…. Sure, AMEX Black Card on file and we are good!

[@roberthull959]

But for real. Im undecided on the haro blackout or the chase pro xl. How do i decide? No shops around me carry either. You guys dont sell complete bikes. What do you do?

[@SupercrossBMX.]

No, we don’t sell complete bikes. But many great bike shops will build customs for you to your specs. As far as the others, try to find a good local dealer in your area that carries good bmx bikes, ask questions, sit on the different bikes, but better yet, go to your local track, make friends with people, and ask to try a few bikes, I guarantee you will be better for it.

[@johndoe-id8td]

Can't nothing is in stock lol

[@SupercrossBMX.]

@@johndoe-id8td Sorry, most shops are getting stocked back up well now. And at the local track, some one has to have a few sizes you can try.

[@simoncarter-by7yh]

I do no . I am 52 and would like the gt pro speed i am 5/3 in hight . Pro or xxl in size i am no change the part of the bike

[@paulmeade3297]

Ok bro!, That’s the Radest Shirt Ever,, how can I find one?.

[@SupercrossBMX.]

Thanks, we have those shirts on SupercrossBMX.com

[@ShreddedKnuckles]

I’m 6’5 246lbs, am I too big for a BMX Bike? Should I just give up on the idea of reliving my youth? Will I look like a Gorilla phucking a Football? I’d like to freestyle the bike but also ride on those days when my wife forces me to go on a bike trail. I guess you’d say I need a hybrid.

[@SupercrossBMX.]

Check out the new 29” BMX bikes and you will be fine!

[@ShreddedKnuckles]

@@SupercrossBMX. thank you sir

[@nakkusuzan796]

Man would you please give out the measurements of the bmx

[@SupercrossBMX.]

Which Measurements are you looking for? All our SupercrossBMX measurements are on the www.supercrossbmx.com website

[@jfs116]

Size of torso =top tubes, long legs you need longer cranks

[@SupercrossBMX.]

Not true.. Longer legs push your torso up and change your back arch, crank length is a separate item all together, We have seen very short Torso, with Long Top Tube, and short legs with Long Cranks... so that is not always true.

[@karmaq8462]

Im 6ft4 on a 29 ?

[@SupercrossBMX.]

At 6’ 4” a 29” Big Bike is fun to cruise but a Pro Xxxl or Xxxxl 20” would feel good

[@karmaq8462]

@SupercrossBMX. yeah I'm 39 , just want to cruise around , still getting used to it again but I find my 29 a little on the big side.

[@karmaq8462]

Also for my son who is 5ft4 should he be riding a crusier 26 or 29 ?

[@davetumolo1497]

If your an adult rider and fall in between sizes for your frame do you feel the rider should go with smaller or larger frame size?

[@SupercrossBMX.]

Go larger for the longer wheelbase for more stability and then run a shorter stem

[@byc1013]

Frames are too expensive

[@usbsol]

Useless...

[@SupercrossBMX.]

Sorry you thought it was useless. What exactly would you like to see?

[@kamaumalone]

Will Supercross be selling the Pro plus size again for the RS7 frame? @supercrossbmxtube

[@SupercrossBMX.]

Yes we just do them in short runs as it is not a super popular size
