Been using Pedros levers for several years now and refuse to use anything else! If I'm purchasing new levers, it's only because lost them or gave them away. These levers have never broken on me, even on the most difficult tubeless road and mountain tirewheel combos. Would highly recommend.
For years, I'd tried every tool I had to stop the chainring nuts from slipping when tightening, but nothing worked. This tool does the job and is cheap. If you don't have one, pick one up before you need it.
