this is a simple and beautiful tool from union foundry, an easy and effective way to fasten/loosen your lockring without having to carry around a chainwhip and lockring tool around with you. if you’re not familiar with the method of rotafixing then check out the video below to see it in action. some really smart thinking in this one, and the beautifully packaged ‘rotafixer T0001-0A’ even comes with a custom produced penfield flannel protector for your bottom bracket. a really great idea beautifully executed.
