Hi all

If you did use this particular tool on your Raven Tour BB, can you describe
how to use it correctly, please. A picture would be great!

Thanks,
Jan

Hi
The small end is a regular spanner for the two bolts on the underside of the BB shell which lock the eccentric in place. It can also be used as a pedal spanner. The large end is used to rotate the eccentric within the BB shell. The eccentric has about three notches into one of which you hook the tip of the tool and then use the handle of the tool to rotate the eccentric to adjust chain tension.

I'd ever seen. Thank you all for that!  :)
