Carbon Fiber vs. Aluminum BMX Bikes: What’s better? - The worlds greatest BMX debate!

[@johnpullman]

The carbon -v- aluminum wheel would be great

[@rickfrisby9887]

Carbon vs aluminum wheels comparison please. Nice job on the video guys!

[@cleomalmin3644]

Yes compare the carbon rim vs aluminum rims

[@carriepatton7811]

Please do carbon vs aluminum wheels!

My wallet says aluminum all day except the Speedlune forks that I run on my 20/24 bikes.

[@jimmietaylor4753]

Aluminum is super lite

[@jgreenlyjr]

I’ve always ridden chromoly but interested in your review. Being off my BMX bike for about 10 years (over 50 crowd) and about to build new bike so nice to watch your review. Thanks Mick

[@cglasford1]

steel is real!

[@BLITZKRIEG1]

that's what my kart frame is made of

[@jacobjames1171]

Looks like a ton of fun out at your track.

[@jimmietaylor4753]

Maybe carbon fiber is going to be lite

[@NTuneLabs]

Those are BOTH beautiful bikes brother!

[@dc-g2280]

I'm lucky enough to have a prophecy Scud evoXL carbon, and a 2003 Supercross evoXL. the Supercross is a really nice ride, and that extra forgiveness from aluminium actually makes the ride less tiring. I also always have that worry of carbon cracking etc?I think carbon is best left for serious riders and tech junkies- I love my Supercross, Def my preferred daily ride.

[@christiantabangay3202]

Sir can you do a test if a carbon rim can survive a street tricks and high jumps and impacts vs. A aluminom

In past years, I would have always went with carbon. But after riding the aluminum, I loved it!

[@devlinweaver1343]

@@kjromero8538 yea I love riding aluminium bikes just because it feels smooth and when the frame flex’s it just makes it a nice bike to ride at the track

Carbon frame on Aluminum wheels is the sweet spot for me….

Lots of people feel that way. You can always fine tune how your bike rides and adjust the parts you use. Tire Pressure, Bar type, stem type, etc....

[@JaredPhillips]

I'd like to see the carbon vs aluminum rims video as well

[@thebentley71]

Dude I'm 52 & my health is failing me. All my life, I've always wanted a nice bmx bike. In the early 80's I dreamed of a Hutch Pro Star & Trick Star. I also wanted a Predator 16 inch pit bike, because I'm only 5'4". I also liked tje mini frames because they were small. My mom was a single parent. In High School I started working, but my priorities were school clothes & a vehicle to get back & forth to work.

[@TORKiT]

Aluminum FTW! Why is Supercross the only place to buy Speedline parts? Off topic just curious.

[@TheDjcarlos67]

I've easily had 40 bmx bikes since the 80s but my 4130 SX450 is the best riding of them all.

[@glenogle2901]

I Fully agree after coming off a carbon Envy back to an alloy Frame i feel like its a better all round bike than pure Carbon 40+ rider

[@kjromero8538]

that was the first time I had gone from a carbon straight to an aluminum. not a huge difference, but enough to feel the difference. a lot easier on the back and a smoother ride!

[@marcduren1978]

Love these videos. Awesome job. Old man on aluminum here lol

What about titanium lol?

[@SupercrossBMX.]

Ahhhh… the dreaded Titanium… such a wonder material… for certain applications… a BMX Racing frame has not been proven to be one yet…

[@lazlo2511]

Alu is more forgiving, carbon not so much... your back is way better on a aluminum! I think you summed it up to personal opinion on the feel, each person will have a different want so basically the test before you buy policy! On this case... watch before you win it! 😉

[@bradleycarroll8360]

Great review leaving me with one more question, Super interested in the longevity of the frames, are aluminium frames more resistant to damage from crashes than carbon?

[@TheAwGooner]

Aluminum can sustain a mild dent with no issues. Once carbon is cracked it will need to be repaired or replaced.

[@franpri77]

I grew up racing BMX (NBL/ABA) and road bikes (TXBRA). When I raced road races I had both aluminum and carbon rigs. Reason being is that I raced A LOT of criterium races. Which are timed brutal thrashings on about a 1 mile circuit for 55+ minutes. Crashes happen often and lots of carbon gets broken so I raced my aluminum rig mostly. My aluminum rig on long road races on various textures of road would beat me up, the frame was stupid stiff but no where near as compliant as my carbon rig. Meaning I did not feel beat up from road vibrations. Given that I am no longer a sponsored rider and I have to pay for my own gear and bikes now, when I head back to BMX this year I will be racing aluminum just from the sheer standpoint that I cannot afford to be sending my frame to Calfee to have the carbon repaired if it gets cracked or replacing it completely if it breaks.

[@mittenstatebushcraft6381]

That's pretty much how I figured it would go. 😜 If I was a younger man with a higher skill level I might choose carbon, but being one of those "old dudes" at 48, alu- mini- um is my choice. Yes KJ, I'd like to see an aluminum rim vs carbon rim vid. This weekend at Midwest some of my riders were like carbon, carbon, carbon and quoting the gospel of carbon and how light it was.......until I took them to the J&R tent and handed them a carbon rim and an aluminum rim. I did the same with one of the dad's. They were enlightened. Anyway....... Keep em coming, KJ. Your vids are not only informative, but entertaining as well. ~Rob Gray Mayhem Michigan Team Manager

[@jameshuff5713]

I'm just a 48 yr old father of a 6 yr oldgirl who started out racing 10 months ago in league. Got her a gate ,practiced everyday for about 3-4weeks. She has a redline mini thats taking her through novice pretty quick. Everyone talks about this at track ,aluminum vs fiber. We'd love to try out the fiber ,but so expensive for me. I want the best for her and i feel bad that i cant afford to provide her that fiber bike,rim. I would trade you one of my 90s elf bikes just get a fiber bike. I know its not worth as much as your bike but . I guees what im tryingto say is id give the world for my daughter. Ride hard guys. Loved the video. 🤘👍
