ENVE wheel nipple corrosion.

Anyone had any problems with UST ENVE wheels regarding nipple corrosion ?

My wheels are just over 18months old and have never been ridden in water, i live in the driest state on the driest continent on earth :p (actually a fact) so its not even moisture and rain is not an issue either.

So approx at the 12-14 month mark i start hearing this rattling noise inside the "nipple chamber" on both wheels and think to myself its only some dirt thats got in there.

But its taped tubeless so nothing can escape into the wheels or stans escape out. The nipples seal the hole from the inside so no dirt can get in.

So then during a ride (November) i notice my front wheel is way out of true, when i get home i see that a spoke is loose but undamaged, i untape the wheel to see that all the nipples have a dusty white appearance (corroded), and 3 of them are nearly disintegrated but theres so little left of them i cant even get them off without cutting a perfectly good spoke.

The rattling noise was shards of alu from the sides of the nipples and obviously the disintegrated one from the loose spoke that is nowhere to be seen. The shards looked to be stuck together in little balls as if they had picked up some of the sticky glue from the Gorilla tape that is sticky side down on the underside of the spoke access hole.

Has some stans fluid possibly escaped into the "nipple chamber" and done this ?

Gorilla tape IMO is crap so wont be using it again.

Back wheel i stripped tonight has also 4 nipples in advanced state of corrosion. Cant do much about it as i dont have replacement Sapim CX ray spokes to replace the ones i would have to cut. I have replacement nipples but cant get a nipple driver to grab a corroded nipple :confused:

So ive rinsed the chamber out on both wheels and will retape them with Stans tape tomorrow.

Is there any fluid i could put in there to help reduce corrosion that WOULDNT damage the carbon fibre.

I have no idea if this is an ENVE wheel design problem, nipple issue or what.

Heres the box.... the proud day it arrived, wheels were perfect and completely sealed. Absolutely no signs of anything either contaminating the box or anything getting inside.

This is something that has happened since i got them, some reaction with tape, stans or whatever.... its beyond me and ENVE are not exactly clued up on what caused it yet either BUT they have acknowledged its happened before, they have an idea whats causing it, and they have gave me a solution which i cant see any reason why it wont fix the problem.

Heres the nipples from the rear wheel, its now finished and fitted with brass internal nipples.

I'll get the front wheel done tomorrow hopefully, it was the one that spoke came loose and the nipple disintigrated.... now its became clear why.

9 of the nipples on the rear were too corroded and couldnt be undone by the socket. It took a bit of time but the only other alternative is cut the spokes

Also in the pic is the alu pillar nipple, what the rest of them should look like and the other one is the new brass internal nipples im fitting to the wheels now. Pictured at the bottom was the worst nipple on the rear wheel, looks like it was ready to let go at anytime.

Click here, scroll down the page to spoke tools, its the 3.2mm square one that i got.

The nipples came from there too, pretty good as he sent it fedex priority and were here in 5 days for $6 shipping.

car bone feels your pain ozzy. what a bunch of f***ing jokers they are. did they really think this through? they thought this was going to work? when building something; if you spend less than 95% of time thinking about how it should be done, all possible ins and outs, then you're doing it ****ing wrong and thats it. this is proof.

Just built up a set a week ago of Reynolds but used Brass nipples. Even with Alloy nipples I would expect that on the Reynolds would not have the issue as bad as you would see the corrosion (If it started).

On the Enve the nipples are hidden from view. If you don't check them then they "could" fail while riding. After talking with Enve it sounds like they are aware of and in process of a solution. From the sounds of it Enve cares about their product and customers. Hopefully a solution is on the horizon with it being available to customers seeing corrosion.

I feel the need to stick up for Enve. I've built ~100 of their wheels and I've owned 3 different sets and have several customers with them. Only one of them has had problems with nipple corrosion. On top of that their customer service is top notch. I've seen them warranty things they shouldn't have, just to keep a customer happy. So even though this thread makes it look like everybody is having this problem my sample size is a little bigger and I'm inclined to say that it is a relatively small number of wheels that are suffering from this.

I am with you on this. I have seen Enve warranty some things that no way would I ever think they should have replaced. I have built hundreds of Enve rims and have not seen a single case of nipple corrosion. I do coat the nipples in heavy marine grease on the outside and inside on the threads. I started doing that from the beginning because of the problems I have seen with galvanic corrosion between carbon and aluminum parts.

I have actually seen many different parts on bikes have corrosion issues, it is not an alloy nipple problem. There are so many dissimilar metals touching each other on bikes that corrosion can be a big problem depending on your environment.

The decision to use non anodized nipples still baffles me. ENVE employs some of the best engineers to design a rim but then go with a nipple that compromises longevity and rider safety? Where were the engineers when this business decision was made? Classic example of the left hand not talking to the right and a business person making an engineers decision.

To all the engineers out there - don't back down when an accountant, product manager, or supply chain inserts their misguided opinion on your product.

That's when you make them sign-off on your design spec/drawings...cite names, company(s), and your objections, and have it locked into the project documentation...from experience in the EPC(L) industry. It's Engineering, Procurement, and Construction...what they don't tell you in the private sector is the "Litigation" part ;) New grads, beware!

A short update from my issue. I cant say too much but im being looked after very well by ENVE on this issue now and can 100% say my faith in their Customer Service Dept is restored and they have surpassed what level of duty/care i would have even expected.

Hey Ozzy, sorry about those issues you are having. That stinks, but at least they are taking care of you. I do have a question, why not ti nipples? Is this not an option? I am also looking into Reynolds wheels with AL nipples from I9. I will ask if they have seen these issues as well.

Yo Maz, the non-anodized nipple issue is a first.... an soft alloy internal nipple in a tubeless wheel, sealed from the inside apart from a possible leakage of Stans through gorilla tape in a dry and dusty enviroment.... who would have guessed the reaction.

I was 100% alright about fixing the issue myself but now ENVE have got on the case and its all good.

I mark a door by using a vernier caliper for accurate distance and put small pieces of tape there. then I just line up the tape I want at a certain width with the small ones I already taped to the door. And then I just cut it off at the corner. Whats left on the door is the correct width tape.

Edit: sorry I was supposed to quote ozzy but somehow I was to incompentent to actually pull it off.

After reading Ozzy's account and then hearing a little rattle in my rear wheel, I decided to have a look inside my Enves.

Now the front wheel was re-strung 3 months ago after a big off and the rear has been on for 12 months. I stripped down both wheels and found corrosion as suspected. Green Font Metal Silver Still life photography


So I replaced all of the nipples with brass nipples this time, hopefully I will get better wheel life out of them. Some of the nipples were so corroded that it was difficult to get them out or to get the spoke out. 8 spokes were damaged due to the nipple corrosion. I replaced a 9th spoke because I must have chomped a branch or something sometime.

Some nipples were destroyed, here are some with a little pitting Photograph Rock Grey Metal Rectangle


I am showing this for the information of people in dry humid climates, watch your nipples on carbon wheels. As I have said above, I have had the same problem with DT Swiss carbon wheels as well. I'm not here to bash any one manufacturer, it is the materials that we are working with here.

Kudos to Enve if they work to resolve this, as the problem is only prevalent in particular climates.

Thanks Ozzy for your story, it helped encourage me to check something I should have checked earlier.
