Hi @Mina08, a 2.5mm magnet may work, but I'm not sure. It does not have to be flush with the cog, but it does have to be powerful enough to trigger the speed sensor. If you use a high quality and very high strength neodymium magnet it may work ok.
Just a quick update here on the LSS. A few people had some issues with the clip ring that attaches the LSS to the rotor. I spent some time re-designing and prototyping it and have a new design that should both provide a more consistent clamping force (i.e., more tolerant of small dimension...

Hi @AleksEU, I'm glad you like the LSS! You can buy a spare planet gear here:
LSS Planetary Gear v2 by JD_3D on Shapeways
Which should get you up and running. I'm still looking at ideas and methods for increasing the life of the small planet gear and have a few different ideas I'm exploring...
Thanks @G P Smith! To answer you questions, for disassembly, take 2 butter knifes and slide them under the cover and then gently work it loose. Also use a screwdriver or butter knife on the clips and carefully un-do each clip so as to not damage them. I personally do not use any lubrication but...
I've given this some thought and since the small planet gear will wear out well before the other parts I think the best thing is to release the design file for the small planet gear. That way people with access to a 3d printer can print their own replacement planet gear if theirs wears out...
Thank you @dogzilla for your support! I will always try to improve the product, and yes it has been a lot of work prototyping and supporting this. You don't need to replace the entire unit after 500+km, you only need to replace the very small planet gear and those can be purchased separately for...
Good point about the gear teeth. That is something I think I can improve on. Right now the design is a bit conservative in terms of the gap tolerances as I wanted to make sure it would fit for everyone. But tightening up the gaps and improving the teeth profile could help the life significantly.
PEEK would be great but unfortunately Shapeways doesn't offer that material as far as I know. I've heard it is very expensive. Thank you for the offer on printing it. I have ordered the planet gear in aluminum (which should be even stronger than PEEK) so I'm hoping that works out as it is...
Hi @FlatSix, thanks for the feedback and photo. In your case there does seem to be quite a bit of wear on the planet gear. Thankfully the other gears look ok (which makes sense since they have a lot more teeth). I'm always trying to improve the design and I've been thinking about the best way to...
Hi @VeloMikey. No, I haven't yet made any versions to support specific rotors other than the universal rotor mount I made (which requires zip ties or wire to attach to a rotor). Ice Tech rotors do seem to be one of the more popular aftermarket rotors so I suppose that's a good place to start...
Wow, that ring gear is super loose! That's the problem right there (it's moving causing the large gap and the planet gear to skip). I think the little planet gear has wear because it has been skipping and wearing the ends of the teeth. So I think you'll need a new retaining clip. Not sure how it...
Hi @TPX, thank you for your post. I remember you helped take measurements on the DT hubs way back in January (thank you for that). I think you are the first person to report a wear issue on the LSS. Looking closely at the photos I do see some wear on the planet gear (which is to be expected)...
Hi @McInner1,
I use a 3d printing service (Shapeways) to print and ship my design directly to people who order. This is much better from a customs point of view as they have a place in both the USA and Europe where they can print it (I'm in the USA). But this is why there is no magnet. Let me...
Yes, as @TMS showed you can get a 3-1 gear ratio by reversing which part is bolted to the rotor. Since some of you asked here are a few of the issues I see with the 'copy' product:
1) 3 rotor bolts used to attach one of the parts. May not be able to achieve proper torque on those bolts and they...
Thanks for letting me know. I suppose I shouldn't be surprised as some of you even warned me to patent it way back when I first invented it. I really hope people will continue to buy my original and support me as I've supported all of you here :)
The copy one is not identical and has, in my...
