Has anyone found a cheaper sensor ring option? (42 slot).

[Rideit]

I am looking to have three different rear wheels at the ready.
The MSRP on that part is a little ridiculous, imo.
TIA

We can't even get them at all in the USA

 

[steve_sordy]

As long as you get the correct material. I doubt that any old metal will do.

 

[Rideit]

Well, yeah, that’s a given..

 

[steve_sordy]

Well, yeah, that’s a given..

How are you going to do that?

 

[nowayfra]

Try different metals? I’m sure it’s an easily identifiable steel alloy, lol

Its for a "hall-sensor", google it. The alloy just needs to be ferromagnetic, means if you put a magnet onto the metal sheet it needs to stick.

 

[Rideit]

Yeah, that’s kind of what I was saying. Of course I would try a basic ferrous metal disc first, lol.
That’s what I meant by ‘easily identifiable…

I just registered after seeing your post, but don't think I can send PMs yet. Would you mind messaging me with where I could find a CAD/step file for this ring? Thanks!

You wouldn't want a basic ferrous metal, it would rust quickly. I was assuming that you would have picked a stainless steel, but some are magnetic and some are not.
Anyway, thanks to @nowayfra you now know that it has to be magnetic, and I suggest stainless steel. eBay has some, but Google "magnetic stainless steel sheet" for other options.

Thanks, great tip! I was aware of that, but I figured I would ask whomever water jets or laser-cuts it.
Cheers!

What's the MSRP you are seeing in the US? I picked one up from a UK Amflow dealer (where I am based) for about £9 posted.

Unless you have direct access to laser/water cutting machines I think you would struggle to get a one off that cheaply...

 

[Rideit]

I just looked, there are NO parts available from the Amflow USA site, unless I just don’t see it.

Yes they are around €10 in the EU - for example: AMFLOW GESCHWINDIGKEITSSENSOR RING 42 T

Correct. I asked Amflow and they said “soon”.

 

[Rideit]

Then I’ll probably hold off. I was going to make 50 of them, as the only price I found here was $59.00.

Yeah, I discovered Amflow had pulled all their parts and accessory info off their site while trying to look up some weight figures for the stock parts on the bikes. Weird. I did discover Ronhacks lists a lot of accessories still, and is acting as if they have them in stock. I didn't see the sensor ring listed but, given how many small parts they seem to stock (everything from brake hose guides to chainstays) it seems like it might be worth checking with them if you're in a tight spot and need one soon:
