This?Trying to find a new one, seems to be out of stock everywhere. Not the intensive reservoir, the main one. Anyone find one of these recently?
I purchased this cap as a replacement. It will fit sort of, but doesn't fit very well. It's not very tight and at my last track event, it came off never to be found again. I ended up buying another one of the same because I couldn't find anything else. I don't have a better suggestion, but thought I would give you my (not so good) experience with this one.This?
