Comments about Park Tool FR-5GC Hyperglide Lockring Tool with Guide:
Make sure to order the proper tool! I first ordered the freewheel remover FR 1 / 2, which LOOKS like it should fit any Shimano or SRAM free hub or freewheel. NOT SO. This tool fits Shimano and SRAM free hubs - that's where each gear is removed from the hub, not a unit, which is a freewheel. This tool is to remove the lock ring, so it must be used along with a chain whip.
Bottom Line Yes, I would recommend this to a friend
