Congrats, Marco! Great work!
• A bike, pretty sweet
• An old bike, still pretty fun to ride
• Unicycle, no brand name visible

I hate crappy shifting so this is import to me.

If I know these work with sram cassettes im in for a few.
Mine has been proofed for long and it's softer by far, each click makes you happy ;) I entirely redesigned the teeth to work smooth and soft while we're climbing.

Finally I've never tried the kickstarter platform because only few people were involved and hence I ordered the first 50 ratchets straight away.
I commend what you've done. It's a great job getting these things produced.
I'm waiting for the SRAM force cassettes to become available and I'll be shifting most bikes over to 12 speed using ratio tech or your solution. I'm just stuck right now 🥺

Good job 👍🏻
Thank you, now I understand ;)

Thank you @gwerziou. The first 50 units will be shared with Spaniard colleagues members of www.foromtb.com, we shared cost and we paid 25€ per unit. As there were only two people that reached me through weighweenies, I gave up with the kickstarter idea and I guess I will release few units as "homebrew units" via "e b a y" for those could be interested here. I don't want to leave the designed on thingiverse because it will let someone making money with something without warranty despite it has been tested.

Right now I cannot response you questions through private message chat because I'm new here.
