Review on HCW-5 Park Tool Lock Spanner (109917) by Corey Listner

I regularly use Lifecore Assault Air bikes at my gym, we have 20 of these and I needed a tool to remove the bottom bracket lock ring and it did does its job perfectly. Why 4 stars and not 5? Price! For a simple piece of metal that has grooves cut into it, you would expect it to cost a lot less. But then again, park instruments are always expensive. Anyway, it's a good quality tool, it does the job and I'm happy with it. If you are planning on using it on a bike I would suggest you take a look at the bottom bracket and see which lock key works with your particular bike. needs. This works on the Assault bike, but MAY NOT work on your particular bike. Many bikes use different wrenches depending on the bike model. Just snap a picture of your locking ring and compare it to the many wrenches Revain has to offer. Most likely they will have it. Much luck.
