I learned a ton from this, good stuff.

@@LuescherTeknik Quick question. What is the model and type of transducer you are using for crack inspection on carbon bikes?

Dude can you help me out ? I have a question, regarding one Carbon Full suspension ebike frame, i'm interested in..

Well said!

Gerald G After working building sattelites, then wrenching in a shop and cutting broken frames up, I agree!

Hopefully make progress

Best reply yet! but...They question should be how to buy one of the bikes this guy builds for himself!

I'd love to have him with me when I'm looking to buy a new carbon bike (second hand off of kijiji (Canadian craigslist))

I wore custom shoes he made for about a year. Brilliant. But like his bikes, very limited run (or once offs)

So he makes shoes like Adam Hansen? Would love to see an example of his work in this area.

😂😂😂😂😂I was dying when I read "hands down" in your comment. Especially watching this guy talk.

I knew it'd be a gem of a video once we tee'd up Maven to meet Raoul. Based on the result, The Maven nailed it!

I pointed out the photos of you on the TT bike on the way out mate. Fitting you within the UCI regulations had to be one of the greatest engineering challenges of the last decade for sure! ;)

Like a crushed pretzel. Heaps of fun though. Loving what you and Maven are doing.

Yeah mate I gathered he's a very interesting bloke.

Johnny Woo You are absolutely right! I bought 2 titanium frames back in 2003.One is my winter bike with son and b& m lights,the other one was my lightweight project and with around 8 kg it is about 2kg lighter than the winter bike(60cm frames!). I did never regret that buy-both look brandnew and they also ride like brandnew.Outstanding performance. You can hit the tubes with a hammer and you will barely see scratches.Best bikes i’ve ever ridden-the flexing is perfect for the bad roads i’m riding,bad weather doesn’t affect me anymore. And at age 17 years there’s still value to the frames.And maybe after my death someone will decide to turn them into a ✈️ plane. You can also buy them second hand🤙

humanISvegan definitely! I’m on titanium roadbikes since 2004-i got two identical frames with different setup. One like a randonneur and the other one as a lightweight.They are still like brandnew,although both are ridden hard. Summer bike and winter bike.Awsome belgian handcrafted masterpieces! But these days you can also build very light steel frames,very stiff with oversized tubes.I also have a steel bike just to have this special feeling on the road! 🤙

Nothing wrong with aluminum, it's still strong enough.

Aluminum does have fatigue life lower than steel, and is more prone to ride harshly, although my 90s Redline Conquest aluminum Cyclocross frame rides really smoothly. My 2018 Raleigh RSX aluminum rides hard and stiff, though it's fast. My favorite ride of all is my '95 Merlin Extralight titanium- very very nice.. Many experienced for decades riders such as I will prefer Ti and steel.

I'll stick with my titanium frame

lol

Yeah...

Thanks mate.

Great Vid Maven...that Guys a Carbon Zen Master:)).... i hope i fly in his Tail Planed Boeing Planes:))

That'll be that sooper, sooper-dooper hi mod carbon then! I've idly considered setting up a nice little carbon repair business myself, but after watching this video I think it' best left to people who actually know what they're doing.

I thought the same

J S company's don't give a fuck, as long as it meets industry standard, Hell who cares anyway we're the dumb ass people paying 5_10,000 Dollars on a bike. I would pump them out too.

lol

Ye

Made it unwatchable for me

then u were not interested in watching it.

fool

Thanks for the comments. The landing gear is often made of steel, the Aermet alloy was created for F18 landing gear. Carbon is good for some things but not all things, the same as metals, that's why there are no good Ti forks available. Also note that they typically do not weld structural metal parts on an aircraft. There are plenty of metal bikes that have cracked at the HAZ around the welds. The recycling is problem with lots of research going into it right now.

Does heat treating after the welding on metal bikes (i know steel is sometimes brazed so isnt affected in the way welded steel is) reduce the cracking problem around the heat affected zone, or is the area around a weld always going to be a bit weaker?

Wonky Lommiter You are correct. Aluminum frames require heat treating after welding. Keith Bontrager introduced special gussets to reinforce weld effected zones on mountain bikes in the late 80s. They were copied by many manufacturers.

Excellent repair too

Youch! Bloody plastic bag!

Mecanic sounds more respectable

Sorry but you're wrong.

+Fredrik HL but I phoned every 6000+ viewers who watch it and they personally told me "Hi Marty. Yes, I paused the video at the point where he spoke about carbon wrinkling and checked my carbon bike instantly. Thanks for the call Marty. By the way, how did you get my number? Bye." It took a while Fredrik HL. I hope you believe me. I know Fergal Manergal does.

Not unless you have unidirectional.

Guilty. Didn't get a good look so I'm not sure what to compare it to. My Jamis is unilateral.

no wrinkles im my 27yo steel frame lol

my girlfriend masturbates with hers...

better yet test him to see if he's made of carbon fibre as its clear he's trying to take off

He must be part Italian :-)

I think he's epileptic.... Or a musical conductor in his past life.....

He'd be speechless without his hands.

You may consider titanium too. I have one and I'm loving it.

Ive had 2 carbon boardman frames crack within 3 months , im getting it exchanged for the aluminium version !!!

I used to manufacture and inspect carbon structures for aerospace and satellites. Believe me, you, myself and most consumers could never afford a bicycle of this quality. WHY do you think most bikes are manufactured in Asia???? Asian quality is frequently crap and it's very apparent there is little to no QC happening. I have seen numerous companies try to save money manufacturing in Asia and suffer or fail for it. Human safety, quality and reliability are very important to me! High reliability manufacturing is what I did in a 30 year career! Steel is real!! You can SEE the quality. I ride custom steel and aluminum frames. (Maybe Ill get a Ti frame when I sell my house) I know my builder. Ive ridden with him. If there's any issues, (there never has been) I know who to confront. I know his work ethic, his history and many other riders happy with his work. I can visit his shop anytime (local business) and oversee my frame or others being built anytime. I try to support and buy from local business which helps our economy. I get EXACTLY what I WANT!!! Not what some brainless marketeer 'thinks' I need. My builder is a very small one man business to keep costs down. I can get a really nice frame that can last a lifetime for under $2000. It's a killer deal in my book.

bigpun2k6 Youd never know how good your frame is until you cut it apart to inspect the lay up and quality. Ive done this on numerous crashed carbon bikes. I was a mechanical inspector building carbon satellite structures at one time. I know what to look for. I'm also a machinist and high end bike mechanic. Ive built high performance motor vehicles. I know what high reliability means. I haven't seen a single carbon frame that would pass muster in high reliability manufacturing. Ive also precision measured well over 100 press fit bottom brackets for interference fit bearing tolerances. I'm curious as to why they wear out so fast and are so noisy. I haven't found a single pressfit shell that meets accepted manufacturing industry interference fit tolerances. NOT ONE. There's quality for you and as an expert I call it shit quality. There will always be fools such as yourself willing to believe and pay for marketing lies. I have experience in real industry. I KNOW BETTER!

That's exactly what I want to know ?? Or better yet who calibrates the calibrators calibrator ? Fck my head hurts !!

They use a load cell or load sensor and its a fairly simple circuit that almost always has a way to calibrate itself built in.If you google how they work you'll understand how they are calibrated.But in short they get zeroed out,a tare weight is added and then the little microcontroller does the rest.Once you tell it zero and say a 10lb tare weight the little computer calculates the rest. It's not like they are using mechanical measurement like the actual wrench uses to calibrate the wrench.

Thats the old insanity test joke isn't it.

Your mom does, she’s the grand calibrator

Jesus himself

That explains it....

I think it's probably a extremely common occurrence regardless of cost or brand.

hes just trying to scare sales you. I bet it brings in good business.

I was going to ask whether Canyon's CT scanner would pick those up? +Cycling Maven any idea after your trip to Canyon?

My Specialized has far more wrinkles than my Giant.

8 months later. my carbon frame is damaged.

Aaron ___ how did this happen?

@@RuggeroCappello90 first time chain suck caused a derailuer jockey tooth to press into the chainstay hard enough to dent it. Second time someone crashed bysode me me in a cross race landed on my chainstay. That caused two small lines or cracks. Both were repaired and I still use the bikes.

And you should be. I used to manufacture and inspect carbon satellite structures. Now I wrench in a shop in my semi retirement. I cut up crashed frames and precision measure bb shells to satisfy my curiosity. What I find on carbon bikes shows a very big ignorance of QC. Why do you think most bikes are manufactured in Asia? In 50 years of playing around with bikes, I've seen maybe a dozen damaged metal frames that couldn't be repaired, mostly because they weren't worth the cost. In just 5 years wrenching in shops I've seen dozens of bikes relegated to the dumpster!! Steel is real. Metal is better.

No brand is safe! 😱

Mine is $700

+Cycling Maven thanks for that!! p.s your quality of videos is going north very quickly, won't be long and you'll be youtubes top cycling blogger: -)

+Yeah...Nah...Maybe *vlogger

Pff my entire bike costs less than that!

+Cycling Maven did insurance not cover that, if this is a result of the head-on crash from the tourist driving the wrong way? If so shouldn't the whole frame have been replaced?

The Aussie team tell us it's Tool-a.... but they also accept Thool... Tooolay..... tomato/potato, it doesn't matter. It's just good gear. :)

Shane Miller i second that... but i definitely was embarrassed at how I was mispronouncing it all this time.. lol.. what a newb I must've sounded like eh m8?

I'd say i tool-eh, as it's swedish

It's definitely tooly. www.rackoutfitters.com/how-do-you-pronounce-thule/

Yeah

Exactly what I was thinking, bring me some titanium damn it !

If only graphene would take the floor already...but you need know mate, to roll on metal is to sacrifice insanely substantial amounts of acceleration, top speed, stopping distance, comfortability, efficiency and you'd be throwing much more pedaling energy into any crank movement, plus the topics discussed are for racer-types who should know what to look for in buying such godliness for quality/flaw checks...after trained eyes pass inspection, the bike has about 0.0004% chance of failure..you're taking this video as some sort of "DO NOT BUY CARBON FIBRE" type esque when it's nothing more than any other thoroughly informative video about proper care for aluminium or steel frames which have something definitely over 1 or 3 % failure rate (both percents consider perfect care and flawless manufacture, 1 year after purchase/normal use) what constitutes a chance of failure is mostly always going to be the rider's fault, for failing to properly maintain the bike's peak level of performance and success.the land of carbon fibre is a judgment call of practicality-do you race? Commute daily? Non reactive material has a massive reduction in needing maintenance,no need to freak out about water trapped in your cranks, no constant tightening of every bolt and nut per the stiffness of metal/vibration nudging them off, no warping from heavy use

You have made me smile reading this Triodie 12 old mate.

Triode 12 yes i agree. Ill bet this guy gets sued for faulty work. His knowledge is only just above the person selling the bike. The expensive parts are pressured moulded and vacuum moulded in one piece. The stress fractures are not visible to the naked eye or by magnification. Manufacturers will not repair carbon fibre bike parts. There a really good reason they don't. Once riden on the road the stresses from a metal part on carbon fibre is not able to be seen. This guys found a neiche in the market. After i researched and repaired a few of my own parts i decided against repairing anything for others. The risks are very real and too great. Unless a maker can guarantee all his work i wouldn't touch a carbon fibre bike.

OK this is only one MAMIL's feedback but I rode an early Giant CFR2 for 21 years and when I retired treated myself to a new Giant Defy Advanced Pro 1, the old CFR2 is still being ridden to University by my son-in-law and I'm riding faster than ever on my much lighter Defy. Point? The CFR2 is still going strong but the lacquer did erode off, otherwise no cracks, no catastrophic failures despite the odd drop and instant dismount. So maybe not all carbon fibre is as bad as you think, or maybe I'm just lucky.
