What does MVP stand for?

@@bahoonies Most Valuable Player.

@@itsdeebs5156 Just after I fired off that question to you I decided I was being lazy and checked on the internet. According to Google MVP in business means Minimum Viable Product. Makes me wonder what they might have charged for an already outrageously overpriced bicycle?

Too soon lolol

Invest your savings in a titanium frame-Carbon frames are „less than ideal“ for bike packing 🤙🍀

Look at the incredible strain put on MTBs steerers, you don’t see them snapping all over the place, and a road bike has infinitely less strain put on that area. I wonder if ‘less than ideal’ here is exactly that, perfectly adequate, but not perfect?

and for flight control systems software

But steel and titanium bikes often have carbon forks.

@@londonlionel You can buy a steel fork. Forks are pretty easy to install as well. Ive built my own steel forks and stems. Soon I'll build a steel frame too. But it's your money..... as well as your life.

I avoid the speed bump issue by bunnyhopping them at pace....

Not really into Facebook anyway so not that fussed ;)

To paraphrase Chappelle, Facebook ain't a real place....

Thanks for sharing the information from Bora.

Haha, you think these clowns actually employ competent engineers?

Just rub some snot into that rough edge. Fixed.

Nah, haha, just a statistical anomaly like all these bad frames inspected here.

The scan itself probably wouldn't add much to your production costs. Having to bin 9 out of 10 of the frames you got from your production because of the defects you found however would.

High end bikes are in pretty high demand right now. There's a 'shortage'. Haha, People keep itchin to buy compromise and problems. Why should or would they ever improve when there's already a demand for unsafe garbage that offers a great profit margin?

I thought about a galvanic corrosion as well 🤷🏻

Correct, this is another problem, good to see people have learnt about galvanic corrosion ;)

@@LuescherTeknik well after Zipps massive cock up a few years back with their untreated nipples reacting and cracking rims you would of thought more people would have sat up and taking note. I believe Easton had a similar issue with forks that used bonded alloy inserts as well 🤔

LOL

So snag team issue bikes if/when available?

Special👀Ed: "Innovate (compromise) or die trying" They knew ALL about this recall issue months before it happened. They had their recall hardware in shops ready to go. As dealers we got hardware before the announcement was made. You don't just procure junk out of thin air either. They postponed recall announcement until the day after the Sea Otter event in Monterrey CA ended. Held in their back yard, just over the hills. They didn't want to answer a million queries at this big industry event. That might have been sorta inconvenient for them. Pretty clever huh?

the die part was for the customers

@@brucewayne3141 that's really funny. "innovate or die" could both be aimed towards the customer. it was a threat all along

When I bought a brand new Tarmac SL6 and I found a giant void on the external surface of the steerer tube, right under the stem clamping area, they refused to acknowledge the mistake in the manufacturing process. The void was so big that I was able to tap it with a coin and hear the change of the sound frequency.

Ever wonder why a rotor will often rub when you simply ride out of the saddle on a plastic fork? I'll never buy such junk, but it's often my job to 'fix it'. That's what I call job security! The bike industry creates problems that often can't be solved. At least they're refusing to solve them. Let's not even talk about offering solutions to problems that simply never existed.

It seems like the cutting/sawing of the metal piece isn’t carrried out very wel. The edge is to sharp, not ‘round’. Thats what i understood.

Yes, before a car is released, it is tested for many many miles under all kind of real world conditions, ranging from really cold to really warm countries, to assure it will survive real life usage. How much real life testing is done on bikes? Clearly not enough or otherwise I am sure issues such as those seen on the Aeroad and the SL7 would have become obvious quite quickly...

Probably they hired engineer with fake resume lol.

Cars don't have 2000% gross margin, per S-Works ...

I would have used a longer insert ;)

On a tall head tube it can be significant, you would be surprised how much it deflects.

Also curing adhesive takes time and care to do properly.

Exactly how long do you want your expansion plug to be? This one is already oversized.

@@zygmuntthecacaokakistocrat6589 Past the Compression ring. The black extender portion of the plug that specialized provides doesn't grip the tube. If you get a full compression plug that grips the tube past the compression ring, it should help keep the tube from breaking.

Great question, maybe due to weight or contract factory, not sure. Anyone from Specialized able to answer?

@@LuescherTeknik Just hearing crickets?

Yes, but then it would be listed as too heavy, after the fork has been weighed and shown to be 12.7% lighter than last years model, then they add the additional heavy plug ;)

It would be nice if they started using a kevlar braid again, as used to common practice, but AFAIK only Time still do. Abandoned because it costs probably $10 extra per unit.

@@pmcmpc that would cut into their 700% mark up

@@Sir_Godz Rather more than that ... $250-300 cost for S-Works road frames. Direct from Spec, $5-6k price. But as you say, how could they absorb $10 additional cost within a gross margin in the thousands? Just not possible.

Yes fully agree that the walls should be thicker and the Kevlar layer at 45 + and - should be incorporated as well. This would allow the slot that has been cut in the Steerer Tube to be considered "safe" relative to the current risk caused by the slot in just a fairly thin carbon epoxy layup. I would not have confidence in the current slot in the Tube.

Weight would be one issue. If I bought a top of the line carbon frame I wouldn't like a solution that. A solid non flexible steerer tube could perhaps also cause other issues. That was mentioned in the video that there are flex when braking.

Then you have to provide some dozens of different lengths. And there is a weight penalty, plus you don't want some 100 gram extra in this specific area. It can make the bike twitchy.

@@ralfmimoun2826 i doubt a long bolt and a nut would weigh more than that compression contraption

also when you shorten the tube you'd shorten the bolt just the same@@ralfmimoun2826 but come to think of it, this could be a few strands of dyneema coming up from the bottom, like a carbon spoke in a wheel, then a short bolt and a nut.

This mechanical engineer's perspective: More/less relevant to all carbon bikes as you suggest. Conversation is much more complex than presented. All carbon steerers have some level of voids....just like all aluminum and iron castings have voids and imperfections. This is known and a given. You may know about the strength of honey comb structures. Structures with voids can still be strong. All a matter of degree and there in lies the problem. There are about twenty factors if a steerer will snap versus survive. Head tube length, rider weight, rider strength, handlebar width, where steerer is cut, slammed versus not, stem length....many contributing factors. Likely a 110 lb girl will never snap a steerer on a SL7 that is built worse case even without an internal compression plug. A very different environment for a 1500w elite rider. The real world is much more challenging than the laboratory as much as tests are constructed to simulate worse case. This design is flawed in large part due to the cable routing retainer. Yes, beveling the steerer plug will reduce the stress concentration interacting with the less than perfect carbon layup comprising the steerer tube. This design is negligent and the fix is not straight forward. Each bike set up is different which confounds where the stress concentration is for each bike is the problem. Specialized in fact with a known sensitive design should insert a redundant inner wall in the carbon down 6 inches for every frame. Some high watt pro's do this to preclude steerer breakage at maximum sprint. This would likely add weight to an already porky bike but mostly about cost. The cable routing retainer is an added stress inducer. Trust me when I tell you that the engineer responsible has given long power point presentations to the management at Specialized over this issue. Hurting people because of poor design can cost mfr's millions and even bankrupt companies if negligence is proven. I have worked in R&D my whole life and one thing the public knows nothing about is....out of print assemblies are shipped off the manufacturing floor every day on safety critical parts outside the bicycle industry. Engineers make a risk assessment and if they are wrong, many more people will get hurt. All about profit.

@@lukewalker1051 It seems like building forks using automation rather than hand layup could greatly reduce the chance of voids. Additionally adding an internal reinforcement as you suggest seems like a good idea to do on every fork. And, I am not sure why all bike companies can't run every fork through a CT scanner to check for voids and defects. Last I checked Canyon does this on every fork. IMO it should be done on every fork AND on every carbon frame.

Kinda seems obvious doesn't it? Underspec build a part to say how light it is and then add an additional part to bring it up to spec!

Sometimes they are great.

@@LuescherTeknik Any specific examples? Any current ones?

Take a look at Raoul's Time Scylon 2018 Cut Up and Review. I think I'd be saving up for a Time frame (or a Bastion if I ever got rich; Raoul helped them with their fork): kzfaq.info/get/bejne/Y96SaKWi2c3ehn0.html

Yes, that is the problem, the sharp corner dug into the carbon.

In the bike shop we see lots of damaged plastic steerers. Mostly due to consumer ignorance. They can't adjust a freakin headset, never checked it nor even wondered why the front end knocks around. You're a wise fellow. But it's called INFERNAL routing. Absolutely worthless waste of time to the vast majority of consumers. But it sure looks cool!

1) Hard to say as there are lots of variables. 2) I would bond in a machined insert, like the pro bikes apparantly get.

@@LuescherTeknik I enjoy your content and good to highlight these things, but a less than ideal response. Is there a legal reason why you’re not willing to give an opinion? Also, there’s not really an option for an average owner to set a bespoke bonded insert, I wouldn’t know the first place to look, could attempting that actually be more risky than the OEM solution?

You asked me a question, I answered with my opinion??????

@@LuescherTeknik hey look not trying to hate, I enjoy your stuff, but would you honestly say there is a clear answer to question 1? Is this, in your opinion a safe solution? Because SL7 owners, myself included are now left confused whether to ride this bike. Of course there are other variables, there are with any problem.

@@brettsta72 Re-read his response?

I just call it as I see it.

Too expensive for them, that's why. What's so great about Enve forks?

Gila kan.

yEs

Indeed. Very well said. QC and engineering in the larger bike industry is a huge inconvenient joke. A large marketing budget and a fancy paint job is far more important. I feel bad for unknowing ignorant consumers, but the decision to spend money on problems is their own responsibility. No one else's.

Love the term "eyewash"

Was thinking same thought. I understand modern road cyclists would dismiss bike with anything non-carbon except chain (for a while) but hey, alloy steerer would eliminate problem at minimal cost. And probably introduce another problem with carbon-metal connection but as far I see, carbon steerer also has been mated with crown instead of being integral part. Hmmm.

Lol. Add another 300g to the weight of a modern bike. At this point, pros are gonna be riding 8kg monstrosities.

No, the manufacturers just need to make the carbon ones properly and the bike companies need to be less greedy.

Then you have to worry about the bonding of the aluminum to the carbon blades. Alu steerer trades one concern for another. Not sure which is worse at this point though tbh.

What a joke🤣🤣🤣

No material is perfect. I’ve cracked 2 ally frames. One at the head tube weld another at the chain stay. Neither had been crashed or dropped. Just fatigue and cyclic stress from riding a lot

@@getur99 That seems like an ok falure to me. If you have been riding alot and the bikes are more or less worn out. Nothing lasts forever. Also falures like that are (to me) somewhat acceptable and possible to detect. But if a carbon steerer fail the outcome could be fatal.

I am an amateur with 3 high end carbon bikes and never had any issues. But I am not a 100kg+ barrister or dentist like you or drop my bike or crash.
