I bought this bolt when I purchased a OneUp cog conversion for my 10 speed cassette. Sometimes you need it, sometimes you don't depending on the derailleur and chain ring(s)you have. Save youself a trip to the hardware store or LBS and order this bolt if you're upgrading your cassette with a big cog conversion. It's a buck!

So this screw would work as intended. It was only a buck so I purchased it. Ultimately didn't end up using it because it wasn't needed. I did buy the Goatlink though...so maybe that's why? In any case, with my setup (xt 10 speed med cage, Wolftooth 42T ring, Wolftooth Goatlink, and 11-36 shimano XT casette), I did not need this screw. My recommendation would be to hold off on buying it unless you find after installation of the expander ring there isn't enough b-screw length on the stock derailleur.

If you need to buy just this, not worth the shipping cost if you can find it locally. But if you need other bike parts, throw this in there if you need another long B-screw.
