Hi guys. My dad just bought a used bike, and decided to clean and tune it. I bought the topeak alien 2, which has most the tools i need, but i did forget i need a lockring removal tool, and i really don't want to ask my dad to buy a lockring removal tool after all hes already bought me. Is there anyway i can remove a lockring without the tool, and without damaging the lockring so much that the tool would'nt work? Thanks!
