Tiny 105 shifter lever to brake lever trapper washer part name/source

I am missing the tiny bit of metal that attaches the up shifter of my right 105 (5700) metal lever to the back of the brake handle. It is about the size of a fingernail with a hole in the centre that traps the metal gear lever into a grove in the back of the brake lever.

It is shown in this Korean language diagram.


My LBS said I would have to buy the whole right shift-brake lever assembly.

I thought to use epoxy glue instead but I don't know if that would hold out.

Does anyone know what it is called or even whether it is sourceable, replaceable or mendable with something else?

I'm not 100% on this, but I'm more likely to side with your LBS here and say you probably would have to buy the right lever again, as Shimano, unlike Campy, is not very good about designing products that are meant to be rebuilt. Not a knock on Shimano, but in my experience, small parts like these on Shimano stuff are next to impossible to find.

Maybe buy a trashed shifter and rob the part? Cheaper than a new one.

Thank you. There is no mention of the part on their web site and no customer service contact address for their site here in Japan.

Thank you. I will look out for one. Yesterday there sets going at 120USD and a front-fork-busted-Bianchi racer at 250 USD (it probably went higher) with 105 components. I missed it.

I will try epoxy first.

seems like a nice little project for a 3D printer if you have access to one.

Nice idea, but I don't have access to a 3D printer.

Using the opposite side for a pattern (mirror image?) plus patience and a few decent files, one could make a replacement by hand.

Time to find a new LBS who actually know something about bikes.


Any LBS should have looked at the Tech Docs - SHIMANO Dealer's Manual / User's Manual look at the EV for ST-5700

From your description/image, you want Y6TH02000 R.H. Main Lever Support You should be able to order this part by any bike shop who stocks Shimano. It's here on Amazon as well https://www.amazon.com/Shimano-10-Sp...=1&*entries*=0 or Rakuten Shimano 105 5700 10-Speed ST-5700 R.H MAIN Lever SUPPORT R - Y6TH02000 - Rakuten.com

Thank you very much indeed. You nailed it. I have ordered it from Rakuten.

I stopped going to the knowledgeable Trek selling LBS, after about two years or so, because the member of staff their got pissed off with me when I purchased a carbon frame online. He felt strongly that the LBS need be protected.

The LBS I now go to is staffed by university students who, as you point out, don't know a lot about bikes, but they are happy to put components onto a frame from Velobuild, which enables me to keep riding a low down carbon road bike. Yeah.

If I were of 'the protect the LBS' mindset, I would be still on my (horror) Trek, and about 13 kg heavier.

My experience with Shimano catalog parts is that you will have to wait for the slowest freight ship from China/Japan to get the parts. Figure you'll receive them by autumn at the earliest.

Well OP lists himself as being in Japan, so hopefully that's OK...

Your issue is resolved, but for 3D printers, look around for public use ones. My local library just got one that can be used for a nominal fee. Also, there are websites that will print designs that you upload. I don't know the cost, but certainly less than the cost of a whole printer (but almost certainly not less than the 77c you just paid!)

They estimate they'll deliver by courier on the 5th of June, this Sunday.

Alas, the courier charge was 5.4USD (there was no Japan post option). All the same, it is less than a printer, which is not available in my local libraries.
There are however online services in Japan such as ??? | 3D**********??? 3Dino(**********??) which is pricey, but Kinko's Japan has a really cheap 3D printing start up campaign (till the end of June) at $5 + $2USD per cc of volume, plus $2 per cm of height.
3D**********????5?16**********??2016?5?16??6?30?? | **********? | ********************

Perhaps I will make something cute for my daughter, using blender.

Thanks again to jimc101 for the solution.

The little bit of plastic arrived today. It was 88 yen plus 540 yen for the courier. I have fitted it and the problem is solved thanks to jimc101.
