** DO NOT BUY THESE CRANKS ** -Rnc Superlite Titanium Bmx Cranks! 

As I been saying for like 20 years to everyone, eat a hefty real cheeseburger & do some push-ups & you wouldn’t need this light weight crap that doesn’t last haha! 🤣😉 That is crazy though how easy that happened. I see a few people running them & kinda hard on them but maybe that was just a flaw pair? Like you said, no way that’s one piece of machined out ti or it wouldn’t of done that. 3 pieces & that spindle pressed into that one arm probably. Crazy! Good video for people to see & the company that makes them. Glad you didn’t get hurt homie! 🙏🏽

Had nothing but trouble with Ryan from RNC. I'll Never buy another RNC product after dealing with them. I'm glad you made this video for the world to see!

Draw a line with a marker across the two parts that are moving, then jump on it again. If the lines don't line up then it moved 100%.

I can’t say I’ve ever seen a set of cranks do that or even be sold unfinished. Good on you for making this video.

Nothing wrong with letting people know your experiences with certain things.

I think if I spent $500.00 bucks on a set of cranks & something like this happened to me I’d definitely want a full refund . That’s a lot of cash for something that doesn’t work the way it should . You did right Mike I totally have your back 💯% .

I run a set of the RNC 3 piece cranks and never had an issue. I was thinking about getting a set if the superlights for my next build but will wait and see if the design is improved. Thanks for the thorough and honest advice on these

Thank you for sharing your experience. Glad you didn’t get hurt. Hope you got your money back.

Come back from an absence for this video, wow. Glad to see Fede's still got that integrity i know and love him for.

If I was RNC I'd full refund you and send you another set of cranks. You'd likely make another video on the updated ones and your followers would see the problem was corrected, as aopposed to giving you a refund and this being the first video you see when googling them.

You are on the level and you give an honest opinion, literally the reason I watch. I trust Profile.

The website said the ARMS are machined from solid Ti. The spindle was clearly hydraulically pressed onto the arm. Maybe they should weld the arm and spindle together if they can't get the splines to hold. You should get your money back and the "fixed" cranks.

PROFILE GANG

i've bought tannus tire armors and a ravencrest knife based on your videos because i know we can trust a core rider like Fede. i love the knife and i haven't gotten a goathead flat in almost a year.

Wow! Thanks so much, Mike, for sharing this. I'm sorry to hear that not only are you having a bad experience with RNC product failure, but the fact that some your subscribers are treating you like shit for simply looking out for the BMX community. I know personally that you are not the only one that's had a bad experience with their products. My birthday was yesterday and I was going to build my dream bike and was seriously considering getting cranks from them but NO FUCKING WAY! I've never had a problem with my Odyssey Thunderbolts or Profile and I've been at it for decades! Keep doing what you do brother. The majority of us truly appreciate it. Thank You!

Sucks about your cranks, but at least you didn't discover the issue while whipping a 10 stair, Lol. I went to the website and they are still selling them, but the ones in the picture on the site do not have the visible seam where the spline meets the left crank arm like yours in the video do. The ones on the website has what appears to be some light puddling as though they have been lightly Tig welder. I have been riding for 31 years and have watched at least a thousand you tube videos and can honestly say I have never subscribed to one. Until now!!! Honest reviews are hard to come by these days and although I have not even seen you ride yet, I am subscribing to your channel. Thanks for keeping it real, hope you get squared away by RNC.

I get how some people could find "crank arms are machined from a solid bar" a bit misleading. Though the spindle and arm are two seperate entities. As a machinist by trade, that would be ridiculously hard and nearly impossible for a small machine shop to machine the spindle and arm out of one bar. (This would also double the price at least) The arms would done on a mill and the spindle would be done a lathe most likely.

Yet again we’ll done MR. Fede as that’s a lot of $$$ to be spending. Profile have never let me down 👍👍. Cheers Chris ( from London )

Your the man Fede thanks for telling your truth, cromo 3 piece cranks for life! Im running the fit blunt cranks and kink brace cranks 💪😎

people are mad that their favorite company is getting exposed just like in the last video lol

This same thing just happened to my 2pc 19mm regular rnc cranks today after 4 times riding them. I’m only 162 pounds! It’s crazy. Waiting to hear back from ryan. I have his bolts, love them, no issues with them.

The crank that was pressed-in moved. Full stop. The idea that they could work without welding was a roll of the dice. It came up snake-eyes.

We run the older RNC cranks on our prototype electric bmx and LOVE them. They're exactly as advertised. Granted, Ryan was terse in his communication as he was with you, and also missed his lead time by months. That does make for a poor buying experience. But the product itself was bulletproof. So we just chalked it up to a small company struggling to handle high demand. That's something we 100% understand. The kind of mechanical failure you experienced, though, is genuinely terrifying and unacceptable. It's the kind of issue that could get someone seriously injured at just about any speed - the drastically higher speeds we achieve only makes the issue that much more worrying. One of the advantages of purchasing a bespoke, handmade product like the RNC cranks is supposed to be an increased attention to detail. The fact that such a huge mistake slipped through is indication that it's not just a customer relations problem at RNC. We've got a pair of these superlights allegedly being made for us now (again, Ryan missed his stated lead time by months). We'll definitely be taking a close look and putting them to the test in a controlled environment.

At 7:09 you can see that the spindle is not welded to the arm like it is shown on the website. I think they straight up forgot to weld it after pressing the spindle in.

you just saved me a ton of money and time - greatly appreciated

I know they look cleaner with the press fit however on a high pressure part having a weld definitely makes it safer.

Dude profile , primo , odyssey, FSA all top end well know for strong and safe drive lines , I like the fact you gave these ti cranks a honest go and a review 👍🏻, as I was thinking of getting a set , I ended up going with 170mm black primo hollow bites tried and tested for yrs 💪🏻

i'm always bummed when a company does shady shit like this. i won't buy from RNC. as far as other product videos, I still really want to see you ride front brakes or a full flatland mode bike

Holy sh*t... $550 and you break your leg on a stair set

It clearly states in the line below the one you read that the spindle is made of a different, better heat treated titanium. Still shouldn’t have slipped though, you’re right.

Thanks for making this video! You probably prevented a lot of kids from getting hurt and wasting their money.

Mike -- at 6:06 in the video, you could take a sharpie and draw a line across the two rings, since they are pressed together and NOT one piece, and then put it all back together and hop back on your bike. I bet you the sharpie lines will move apart.

Having seen the atrocious manners of the seller in his text messages I didn't want to say this but it says ' *Crank arms* are machined from a solid bar of titanium' - doesn't say crank arm *and* spindle. Also it states that just the spindle is heat treated which suggests it's a separate part. That being said, they still shouldn't fail like these have.

The two piece design with no welds does make it seem like it would just be one piece of machined titanium, but the description does separate the two saying “crank arms are machined from a solid bar” and “heat treated titanium spindle” The wording is misleading though, especially since they don’t say how they are put together. They just say (no welds) which to them means that each arm is one piece rather than most cranks that weld on the piece for the pedal to screw in and the piece for the spindle.

I've been riding for 20+ years and I the best cranks I've ever run, are DK socials. Can't for the life of me understand why people are hung up on lightweight, when a set of 80 quid cranks will more than do the job. Great video Mike, hope Scotty sees it, as I believe he's running a set too.

I have the rnc cranks. I like them. when first came I had an issue with spline drive sprockets and crank arm not going on. he responded to me after 2 days. I sent them back. had no contact from him. then 2 weeks later new cranks showed up at my house. after a bit of riding, I have had no issues. mine are not welded like the ones in your video. I also have rnc bolts on my wheels and stem (holding up better than my profile titanium bolts) we will see how everything holds up over time.

The description clearly says "crank armS (implying there's an axle somewhere) are machined from one block of Ti (no welds, unlike, you know, regular crankarms) making them unbelievably strong and stiff." i see no deception there. Then it says 'heat treated ti spindle' again implying you now have Ti 'arms' and heat treated Ti 'spindle'. Where they go wrong is saying it's a *2-piece design.* It's clearly not from an 'exploded view' perspective but from an intended usecase perspective, it is. It's designed and intended to function as a 2 piece crank. The design doesn't try to hide that the axle is pressed in. Look at the outside; you can clearly see a round groove where the axle sits flush with the crank arm. You can also see the spindle looking like steel almost, because of the heat treating it's probably not the same shade of Ti that your crankarms have. At least from what i can tell. I bet they just fucked up on the tolerance for what's likely a non-indexed interference fit. They may be happy to fix it for ya. Hey i'd be pissed too. But i would've been wary before i bought them. Their cranks from 15 years ago were much better from a design standpoint (splined is an instant fail in my book)

I definitely thought about buying some RNC cranks when I saw them come out. Been keeping the profile race cranks in my cart just in case I seen reviews like this. Glad someone honest out here.. SUBSCRIBED

I purchased a crankset from RNC and sold them a week later. Lots of promise and beautiful machine work, but need more R&D and aren’t ready for retail. Same goes for new MTB cranks. Judging by the photos online, I believe the design will present problems to mountain bikers. RNC just needs to do more field testing on bikes, not pressure testing in an arbor press, and he’ll have a solid product.

Glad you were able to get your issue sorted ,I couldnt with my seat clamp issue I had .

Now welded on the end his stripped on.. ive been running mine 1yr now on street riding, no probs yet..150lbs street riding. Rnc could be better dealing with customers probs 4sure.. ride for life!!

I stick with chromoly cranks myself and really like Shadow Conspiracy cranks they make. I have two different sets on two different bikes with no issues with them at all. My opinion is I don't need to shave a few ounces or up to a pound makes that big of a difference if you can do something or not. Time, practice, workout, and patience has always worked for me.

I used to ride the animal cranks 175 For 7 years I got new cranks They're polished there the Eclat Maverick cranks 170 I love Em Got those like in January

“Why do you want to skip the ad!?” So I can watch my fricken video dammit

Jeez! I was getting ready to grab a set of these cranks and came across this video when I googled the product. I wonder if i should just continue to buy the Profile Mini Magnutanium!?! Still very light and about a hundred bucks cheaper. BUT, their not gonna be as strong.

Having light parts might be cool but all I’m saying is I’ve been running the Dennis enarson rig cranks for 3 years which were hand me downs from a homie who ran them for a year and I weigh 260 and they’re running strong

Damn man but you are testing products no hate so they can see how they function right and those cranks slipped massively and I would be pissed too man to have the service and how they performed, you are helping company’s grow and show awareness, you have my respect man your an honest man

So just to make this clear. When he says they are Crank arms are machined from a solid bar of 6al-4v titanium (No welds) making them unbelievably strong and stiff. That just means the crank arm themselves. The spindle is separate and is pressed in. There is no possible way to make the spindle and the arm out of once piece. No cranks on any level are one piece they are all 2 pieces usually pressed then welded. Did you contact rnc and discuss this with him. I believe for extra measure he is welding the 2 piece the spindle and the arm together. Just the arms are machined complete.

I’ve always ride Profile. I’m currently riding Profile SS. Glad you caught it in time brotha

Gonna stick with my profiles and ti spindle

i got a spindle last year from them and one side has a issue and i can only put a crank on one side, so its been sitting in my shed since 2020 makes a nice paper weight ill admit. wasted $150 CAD seems to be no consistency with the QC on there products.

Looks like the spindle is pressed into the crank arm. The crank arm may be machined from one solid titanium blank. It looks like it doesn’t say that the crank arm and spindle are one piece. It looks like the spindle is pressed into the arm. If it is slipping obviously it should either be spline on both sides or pressed and welded.

Profile cranks hands down best cranks. I no longer ride but put a lot of years and abuse on their cranks street riding and never had an issue.

another reason not to go with titanium is if you should put. your bike down say skid on a patch of gravel you can get 3000+ degree long lived sparks that can set fire to any grassy areas in the area. i am referring to when titanium plated golf clubs strike a rock in the golf course and starts the greens on fire

4:12 I believe that is supposed to be welded on the end (like how odyssey thunderbolts are welded) .... That's supposed to be the only weld on these cranks

Remember kids, the Eastern Grim Reaper frame…. lighter is NOT always better😅 I’ve always been taught to never run a spline drive sprocket with a ti spindle, these things just seemed pretty no bueno from the start.

You can not cast Ti. It needs to be drawn. You then machine it afterwards.

Fede, IMHO, ur about as real as they come.... I obviously don't know u personally but when I had IG , I noticed you straight up had ur interest posted as in the stuff u liked and those u followed! Most won't do that, they'll only post and like content related to their channel/page so the fact YOU do YOU is the reason I'll always watch! Keep doin what you do, homie! if you ever come to Dallas TX , look an Old Fat F*cker up and u can teach this OFF a new trick !😃

Their description is pretty vague. Probably done on purpose, but who knows. The arm itself is one piece but the non drive side is probably a taper with a keyway or a spline the seats on the shoulder of the spindle on the nondrive side. I'd be pissed too, I know those aren't cheap. QC is so often over looked in manufacturing and it is the most important step. Would be interested to hear what the actual issue is.

This video was well done. And explained.

OG fly dolmen cranks. Best ever.

lose a sub gain a sub, its quality not quantity anyway. respect.

Someone un-subscribed you because you posted an honest review.? I spend that kind of money on cranks & I'd be mad too. I honestly wouldn't be too worried about the loss, lol dude has thin skin or possibly some kinda bias towards them. I just subbed you to make up for him 🤣

I stick the the tried and true profile cranks. They take a beating and last decently long.

Use a marker mark both pieces then do the jump test and see if the lines still meet or dont line up thats how you could tell if the “1 piece” side is moving like that

RNC bmx cranks are jank. Mike exposed the inconsistencies in determined product guarantees. RNC made low efforts in the delivery of the product, beside the quality. Good on you, Mike!

Hey man you said you lost a subscriber welp you just gained a new one I have a 1960s Japan racer one of a kind that's made out of pure titanium

I'm still run wethepeople 22mm spindle cranks with a good old USA bb on my 2002 macneil Heaton. Its a tank but I love it.

I thought you stopped uploading. I haven’t had any of your videos in my recommend or coming across notifications.

Thanks for spending your time and money so I don’t have to. Love your channel.

I have RNC titanium cranks...haven't even used them yet. But mine are different than yours. Mine are actual 3 piece. He'll write back. He did for me.

oh LOL, also he wouldn't offer me a refund for my troubles with his cranks. Said I rode them too much and too hard already... Maybe I should put him on blast on RU-vid too ;)

Crazy . When I get two piece I want two piece. Also requesting a refund and going back to what you trust is 100% rite. Thunderbolts for life here!

I’d always buy a 2 piece like odyssey or verde that come with a lifetime warranty

Holy shit, I'm happy I haven't got them yet.

Mark it with sharpie

Great video bro

These arent welded like they got skipped. The pictures I've seen of the 2 piece cranks have all been welded at the outside of the spindle to the crank arm.

Wow.... Don't buy them at all is a surprising review from you so I'm guessing it's bad.

Wow this is crazy

I will always use snafu mayweather cranks with a ti axle super light for the strength in them

My family runs a business, this is not at all how we would run it. Customers come first.

Looks like they tried a press fit design or an interference fit where you put on piece in the freezer (spindle) and the other in an oven (crank arm) than assemble together As shown looks like it can handle shock loads

hey fede! can you test and see if berd spokes would work for freestyle? I'm very curious to see if they are truly lighter than ti while remaining stiffer

thanks for the warning man.fuck the haters

They look cool, but I take function overlooks

EDIT: Just checked their sight, and as of now, the photos that they are showing show the crank arms being welded to the spindle, so obviously this happened to a few people. As fro how you dealt with this, I think it is 100% justifiable. If you had sent one message or no message and then just made a video talking about how they suck / the company sucks, that would be different, but you have a explanation for everything you did AND you waited 3 months for a part that was promised in weeks. That is something that a company should be called out on, that's something that the rest of us should know. Respect. The arms are made of a solid billet of titanium, and you keep saying "cast" but these are machined. The spindle is a separate part from the cranks. I haven't finished watching the video, but I don't see any lie so far... just a misunderstanding. My guess is that the spindle is press fit and that they just didn't get it right (maybe on this set of maybe on a batch) Obviously the cranks are junk and the purchase experience is unacceptable... If these were made with the spindle as part of the arm, from one solid billet, these things would be thousands of dollars instead of $500. Not trying to say that they aren't pricy or that they don't owe you a useable set of cranks... just that it is surprising that they can make TI cranks for that little money knowing the price of materials and what it takes to machine titanium. I bought some RNC stuff way back in the early 2000's. I still have the cranks and sprocket. They were cool to have BUT they weren't well thought out. It didn't seem like they had any / much research and development as there were several issues and the aluminum they used was too soft. Press fit is when the actually make the hole a few thousandths of an inch smaller than the spindle. They then usually heat one part and cool the other, push them together and once they reach the same temp they are locked together really well. This process is used for a LOT of stuff and works extremely well when the dimensions are correct.

Damn that sucks 😕 I would stick to profile or snafu bmx cranks

Dude they do look sweet though but it’s a shame they move…it should be spline in both sides🤷🏼‍♂️ guess I’ll stick with my redline flight chromo cranks👍🏻

I am willing to bet that it’s not one piece, but rather temperature press fit. Heat one piece and cool the other and press them together and as they acclimate to normal temperature they essentially lock together very tightly. Seems that’s what they did and the process is flawed because the supposed one piece is slipping.

It could be a taper lock just like machining tools. Or wedge you get it

Anyone have any feedback or advice re: the alu cranks they do? Design of both those and the heavier Ti ones look a lot safer - neither are milled all the way through to leave holes.

I think Logan Martin rides them cranks I have the last version and so far they have been great but that new design might be flawed like your showing

I believe Scotty Cranmer or his buddy ran these on their full titanium bike I wonder what experience they had? Also those pedals look awesome what are they?

how much you wanna bet that guy that un subbed works for RNC

And I was going to buy these next pay! LOL

Miss seeing you with Scotty and the boys mike! Definitely glad to see that you're doing your own thing though 🙏🏻🙏🏻 definitely going to sub and catch up and what you got posted already

My bike has been doing this creaking for about a week now, couldn’t find any videos on it.. really hoping my bike isn’t needing a new 3 piece -.-

I had a 2 piece crank that did this and the company had a new one sent to me along with a couple shirts

Wow mike I would be highly highly upset if I spent that kind of money on cranks and they slip I would want a refund to 😬
