77designz Issues Precautionary Recall on One-Piece Stem

Mar 15, 2021

77designz Bar Stem

77designz, a small German outfit that makes chain guides, bash guards, stems, and even a bike, has issued a precautionary recall on the brand's first two batches of stems.

The affected batch numbers are 1PS-35-35-B1, 1PS-35-45-B1, and 1PS-35-35-B2.

Anyone with an affected stem is advised to stop using it immediately and to contact 77designz for a replacement.

77designz says the problem is a material defect caused by a milling process issue during the raw plate production that caused the raw material not to have the same tensile strength in all directions. Because only random samples of raw material are tested in the quality control process, the defect wasn’t detected until recently.

To prevent future issues, 77designz now only uses raw material certified for aerospace use and has added reinforcement in critical areas of the stem. There have been no problems detected with the batches not included in the recall.

The full recall notice is available here.

 Something isn't adding up. Why would a bike stem be designed to have a low enough factor of safety that the grain structure matters during production?

IME, they don't. It was a poor design with too little material thickness in critical areas. Sounds like their trying to convolute the answer.
  • 12 3
 I have da package from we are one and the only difference on the stem is these big chamfer on the sides. I'm pretty sure they were trying to get it even lighter and that is what would cause it to fail. That's just my hypothesis

 @bogey: this. how many more beautiful lofted designs are we going to see without true fatigue, failure, and life testing? Well said bogey, well said.
  • 11 2
 I actually find it rather impressive they test material strength with respect to orientation and that they even have the means to do so.

I know of a few people who work in some of the small UK bike part manufacturers (manufacture myself but not bike industry) and can absolutely guarantee they don’t test their material, they trust the certs and that’s that, no problems in 10 years now but they don’t make ultra weight optimised stuff either.
  • 8 2
 They modified the recall notice to remove the "grain structure" reference. So now they're backtracking and trying to hide it. This seems shady.
  • 10 0
 I've been wondering this for several years now. Imo the stem is absolutely not the area to be counting a couple of tens of grams when strength is paramount to not losing all your teeth and breaking your neck. Way too many good, solid, strong options out there to be shaving grams.
  • 4 0
 @iliveonnitro: They still mention the materials directional strength so the reference remains even if the exact term ‘grain structure’ has been removed, so doesn’t seem too much like back tracking.

 @bogey: I also think it might take about 77engineerz to explain how a milling machine can cause a material defect.
  • 4 2
 @taoin123: It doesn't add up. If the problem was the stem being too light in places, they would have recalled whole production and not just items form 3 specific batch numbers. Looking at how they openly presented the designing and strength testing (and failures) of their bike, it all looks quite honest.
  • 5 2
 @kpickrell: They don’t mean a milling machine - they mean the ‘machine’ / process which he material is put through prior to them receiving it.

E.g. it being rolled into plate, drawn into bar etc
  • 3 0
 @kpickrell: I think they meant mill as in aluminium mill, a place where aluminium is made, not a milling machine, maybe who knows
  • 3 1
 voids in the stock material can be a huge factor. so if a mashine in the production of the raw material fails this can result in faults in the end product. also the grain structure has huge effects in steel parts, should be the same for aluminium to some extend
  • 3 0
 Well, the microstructure (referred as grain structure) does have a major control on the strength of a material. It might be possible that the development of texture (arrangement of crystals) during processing (rolling, pressing, heating) creates anisotropy of tensile strength (directional strength)

 For anyone remotely interested in this stem, check out something with a higher level of engineering like NewMen's one piece or 2 piece forged stems.

Either

EVOLUTION SL 318.2 or

EVOLUTION SL 318.4

Jewelry.

The structure (grain alignment) and strength will always be superior in a forged part.

When I hear "Billet" I don't always hear high(er) quality, I hear "easier to make than forged"

 Ideally you would have the stem forged, then machined for finishing.
Forging has limitations in design and precision, but has the benefit of stronger grain structure.
Machining removes many of those design limitation, and can (possibly) result in a stronger product due to additional freedom in design/geometry.

Generally forging (high upfront cost) is economical in higher volume production, while machining (extremely expensive machining time per piece) is economical for low volume production.
  • 12 5
 you can machine from a forged billet.
  • 3 6
 Forging is superior but the factor of safety in a stem should be such that it isn’t required, there’s a reason most high end stems aren’t forged and don’t really ever fail either, unless you go super light of course.

 I would have one of those but it lacks width. Extra width doesn't look good on the scale!

 @justanotherusername: I mean it's exactly what it sounds like. raw metal is forged into billets to gain strength and an advantageous grain structure, unlike an extruded or cast billet.

 @DirtGuru2: yes. it would. you can overcome that a bit with orientating the billet when machining.

there is no perfect manufacturing technique for something that gets loaded dynamically on all three axis'. You have to prioritize for the main force loads, then over build for the others.

 Define ‘aircraft grade’ - we only use certified material here at work but they often come from different mills and we trust the certs that come with them (we aren’t making stems though)

To most aircraft grade means the actual grade of the material, e.g. 7075 etc, not the certification that accompanies it, especially as the intention for most 7075 is in aircraft / high mechanical load applications, why pay for it otherwise?
  • 5 0
 I think the problem these days and we certainly have it in my day job with aerospace supplied material in Europe is that when you buy aluminium billet it isn’t from billet anymore by which I mean rectangular or square extruded and cold worked , it’s often cut from plate ,which can mean hot rolled , cold rolled or cold rolled and stress relieved or rolled and stress relieved by controlled stretching ,the whole “it matches this specification “ is a bit of a shit really ,unless you specify min yield per cross section and or grain direction you can get material with the grain running opposite to where you wanted to be in relation to the part. It sounds like this is what’s gone Pete tong ......bloody plate cut material

  • 2 1
 @Compositepro: we had 6082 supplied to us 7075 once, that was fun - we notice when 3 tools on a programme we have run thousands of parts off on grenaded for no good reason.

Never did find out if it was the supplier or the mill and if it was deliberate or a genuine mistake.

Wouldn’t at all surprise me about the variation in the definition of ‘billet’ or what they consider the correct grade anymore, we have material that looks and cuts differently from the same parent material sometimes.....
  • 2 1
 I gather the tool heads were detonating because 6082 is about half the strength and surface hardness of 7075 (comparing the same temper states that is) and the cutting edge was digging in and getting stuck.

 @justanotherusername: thats scary .... we used to have to hardness test as part of the procedure , the loss of departments and downsizing of departments saw that go by the wayside and its a check that picks that kind of thing up , i dont know what goes on any more ,

 @deeeight: yea pretty much, we managed to achieve a higher feed rate in 7075 in this case 6 and 4mm end mills) as it is so much less ‘gummy’ (technical term haha) than 6082/ 6061 - you just heard the tool ‘load up’ and ping off if goes, Of course you replace it as these things can happen and ping, there goes the next one leading to some more thorough investigation....

@Compositepro - Yea - we were pretty upset as you can imagine and actually received compensation from the stockholder, we had all of the certs etc and numbers matched but it was tested and was 6082 not 7075.

 @ninjatarian: Can't believe they will be changing to "certified" material. Cost would be ridiculous. This thing was 69g FFS so I think that is far more likely to be the explanation.

 @G-Sport: What do you mean by certified?

Every single order we make for aluminium is accompanied by certification, it tells you its composition and where it was produced, if material is mixed from different 'parent' batches it is all marked on the material and the certs are provided to show this.

We pay no extra for this, order our material from a completely standard supplier, not an aerospace specialist, every supplier we have ever used besides some wierd back-street guys we only used once supplied certs - standard practice.

I am not ISO approved but believe ISO shops cant use anything but material with certification.
  • 1 0
 @justanotherusername: I work at an ISO shop and we cannot use any material that does not have a cert and we take it a step further and test all material to make sure it is the correct grade. We also order material with the grain pointed out so that we can align with the part depending on need.

 @justanotherusername: @blurringthelines:
Sorry, I should have put "Aerospace certified". Occasionally in the past I have had to buy actual aerospace certified material because the size I need is sold out in the normal "commercial certified" lengths. Price has been between 3x and 5x, because every single length of tube was tested and had a full report of its own.
The press release used the phrase "certified for aerospace use" which to me sounds pretty unequivocal.

Also; 69g!!!!

 I had a batch 1 split along the centre but thankfully saw it. Was only offered a replacement (no refund).

My batch 2 stem that I am currently riding is a 45mm, yet it appears to be missed from the recall? Russian roulette......

 Missing from the recall means there is no issue with that batch so your stem should be fine. I had an issue with a RaceFace Turbine stem where they'd made the face plate slightly too small so it cracked when tightened, I rode for about 3 days in Wales before I noticed it.... I was sent a replacement but RF did a recall on the original face plate design a few months later. I've been riding that stem for about 8 years now so it's not a worry.

 I was actually considering this product-with a big fork and 29er wheels, my flat bars are near level with my seat.

But there were no reviews, and I’ve had bad luck with light stems. This announcement means this one would just live down to expectations.

 It's so funny to see these pricey rainbow colored machined stems so popular when a near net forged stem is lighter, stronger and usually cheaper. It's like were back in the 90's with all that machined shit breaking, have we learned nothing?
  • 1 1
 Well all the ‘machined shit’ isn’t breaking though, is it?
  • 1 0
 If I were to design my own steerer/stem/bar setup I would machine splines at the interfaces. You would have less needed clamping force, adjustability in 3 (or your preference) exact degrees of rotation, and know your stem is square to the fork 100% of the time. The tube walls would need to be slightly thicker, but the force would be evenly distributed so you wouldn't be relying on a thin plate or rib to keep your teeth intact- it would just have to locate, not necessarily squeeze. Works pretty good for cranks, and they see serious torque

 And when you crash and your bars are against your ribs while the front wheel hits a tree? Wouldn't you rather adjust a slipped stem back to position than spend a few months nursing a broken rib or two?

 Ha ha ha ha ha, there is no material defect, the shit is just to thin for rowdy riders on long ass bars. What did the Germans think would happen? Have we learned nothing sense the Hindenburg disaster?

 Welcome to the 1990s when anyone with a machine shop or wanabe machine shop thought they could design and make bike parts. A whole new generation gets to loose face over weak, light CNC parts because their makers know nothing of metallurgy or adequate design verification and validation. Those who can't be bothered to know the history aof the bike industry re destined to repeat it.

 Single clamping bolt on the bars AND steerer is a hard pass for me. Oh, and they crack!!! Shocker!

 It’s a two bolt steerer clamp. The lower portion of the stem is obscured by the handlebar in the photo.

 @TyBrenninger - This does not affect Da Stem that we produce in our Kamloops facility with locally sourced raw materials. Thanks for checking with us.
