Except that I bought the 30 tooth one. I like having the 2:1 ratio, but 3:1 would be even faster.
But I will change the link to the 30 tooth one. I hadn’t realized I put the wrong link in.
Also, not sure why all the links are showing in Italian now, but they are the same, one just needs to change the language on the page to english (or whichever you prefer).
