Incredibly useful tool for swapping disc wheel accessories
by OldanSlo

Fits internal disc lock rings, external disc lock rings, and Shimano/SRAM cassette lock rings. Add chain pliers and can make swapping cassettes and rotors around almost fun. Sturdy tool with plenty of leverage.

Feedback Sports BBCassette Wrench
by Jon Tate

Have you ever fumbled around with a cassette lock ring tool an adjustable wrench a chain whip? I have and it can be a little awkward, to say the least. Have you ever stripped the threads of a cassette lock ring on a brand new cassette because your lock ring tool shifted a little as you placed your adjustable wrench on it. I have and it sucks. This BBCassette wrench from Feedback Sports is just the right tool for the job. I've removed and replaced cassettes with a lot more ease and less worry. As a bottom bracket wrench it is so much better than the little plastic thing that is supposed to help you with FSA or Shimano Hollow-Tech BBs. I like a combo tool like this and for $20 dollars it is a good deal.

Works well and looks good doing it
by Sean

This tool replaced TWO two-piece tools that I previously used. It's very sturdy and attaches very nicely. It's a very well made tool that does exactly what it's supposed to do.

Handy Tool!
by SHBiker

Perfect! Can't comment on the BB side at this point, but I used the cassette lockring side of the tool to install a shimano 11 speed cassette on my wahoo kickr core last month and it worked perfectly - comfortable, sturdy and easy to get enough leverage. Feels super solid and well made, a welcome addition to my toolkit for sure!

This is a great combo tool for cassette lockrings, Shimano bottom brackets and external disc rotor lock rings. Finish quality is excellent and very useful in the garage and for bike travel assembly.
