I pulled my Shimano BB out today and found a big puddle in the bottom of my BB. Anyone got a solution? I haven’t pulled the shock off to see if there is a drain hole down there, but if not I’m thinking it’s going in through the shock bolts or chainguide bolt holes. Any ideas?

Thanks! I’m thinking of doing something like this over the winter.
Can't remember exactly where I read it but pretty sure they have a drain hole on the underside of the BB shell.

Usually it is blocked by the sticker.
Don't drill an unnecessary hole.

Like I said earlier in the thread. The sticker blocks the drain hole that is there from the factory.
