found sjs cycles on google, but shows : 'more stock due in 28/03/2018'
I just mailed some local shops, hope one of them can get a replacement faster...

That’s what my LBS told me.


Is there any other similar screw that we could use?

Contacted bike-discount.de (where I bought) came back with a nice answer :
Thank you for your inquiry and your interest in our products.

Unfortunately, the desired product is sold out and we won’t be able to offer it in the future.
Also contacted sjscycle but they still think end of march.

Same problem, they are made of butter. Pretty crap considering the price.

I have bodged it by cutting a groove in the head so I can loosen and tighten with a flat blade screwdriver. Problem is that I am losing fluid because I can't get it tight enough.

Considering drilling a hole right through, tapping it and then screwing in a new bolt with hydraulic loctite to seal it up. May work better.

Anyone got a better fix while we all wait for replacement parts?

I had to make a Torx into it so that I could unscrew it.
So far all ok.

Help me to better understand exactly how the shops negligence has became your problem?
Ironically, I now have a much better perspective on the issue. I decided to replace a sticking front caliper and low and behold, my Pedro's allen wrench failed to loosen the cap, and instead slightly rounded the hole in the bleed port cap, thus I also had to resort to the torx bit method to remove/install the bleed port cap. :oops:
Of course looks like this has become such an issue that Shimano is nearly sold but I was able to source a couple from an Ebay store based in Taiwan and may even have the replacements before summer. :roll:

Yepp it seems that many have the same issues as the availability of these screws is just terrible!
My LBS keeps telling me each bmonth that the ETA has been delayed by one month..

ST-R9120, ST-R8020, ST-R7020 all use the same Funnel Adapter Y0C698050, so thread on Bleed Screw is the same, and exterior looks the same

Still looking for a replacement screw for my shifter....
eta is being delayed again.

Don't think the Y0F398030 is a alternative since the R7020 groupset is not available yet ?

Seems like tapping in a torx bit into the rounded allen head is actually a practical solution, but if a replacement bleed screw is sourced, my advice is do not over tighten the screw. :beerchug:

Beyond Aero in Berkeley, Ca has at least a spare one I think. Beyondaero.com for contact info.
