Review on Wolf Tooth Components 25Mm B Screw by Jon Dugan

Revainrating 5 out of 5

Worth replacing your original B screw.

The original Phillips B screw is worn out. This item has allowed me to get my derailleur to work with a cog that is three teeth above spec. The old one was fully seated and didn't come out easily. I cleaned the eyelet, smeared it with oil and on a new thread. it went in easily and the hex head works much better.

Pros
  • Cycling
Cons
  • Questionable purchase for the elderly
