A replacement top-cap for your Eclat Stream Forks.
These come in two sizes, so be careful which you choose.
If you bought your forks in 2012 or 2013 the wider thread (B) is your boy.
If you bought pre 2012 or 2014+ the finer thread (A) is the one for you!
This also fits m24 forks ie (odyssey r32, f25 etc)
