The very mysterious US made Ruff Bike Co CSK guard sprocket that I teased a couple months ago is now available for purchase! You can buy the sprocket alone as well as guard options on the website. $82 USD for the sprocket alone, extra $12 for the insert (19mm and 22mm options available), and an extra $10 if you want the guard with it. Here’s what Ruff has to say about it:

“We designed some 25 and 28 tooth sprockets that are compatible with Profile steel spline drive inserts and machined to accept select 4 bolt pattern nylon guards.

These sprocket were manufactured in the US from 7075 t6 aluminum alloy.”
