unbelievable. the UNION FOUNDRY rotafixer T-0001 lockring tool works on the principle of simplicity. first, you have to know how ROTAFIXING works. it’s a manner of removing or re-tightening your fixed-gear cog without using a chainwhip. but just because you don’t absolutely have to carry a chainwhip around doesn’t mean that you don’t have to carry a lockring wrench around. i mean, you still have to loosen/tighten your lockring every time you loosen/tighten your cog, right? so what union foundry did was to create a "cog" with a lockring tooth on it. put the "cog" over your lockring with the tooth in the little slot, and now you can rotafix your lockring in the same way you rotafix your cog! (albeit in the other direction.) union foundry has even gone so far as to partner with PENFIELD to make a flannel protector cloth for your BB shell so your chain doesn’t tear into your sweet matte black paint job when you do this.

you know, if i got one of these, i could totally do away with my TRIXIE (to which i’ve added a chainwhip attachment). now that i have the MONKEY LIKES SHINY 15MM U-LOCK SOCKET, i really don’t use the 15mm end of the trixie anymore, and that leaves the chainwhip and lockring wrench as the only parts of that tool that i need.

PROLLY did the review and provided the pic here, and his post states that this is a special order thing, so i don’t know when or even if i’ll get it, but i’m VERY tempted. this would significantly slim down the tool kit.

UPDATE : HERE’S where to buy it. 80 bones.
