I am having a hell of a time keeping my chain on the front when going fast over rough trails.
Bike is a 2013 Rumblefish and from what their site saws has a Press-Fit 30 BB.. E Thirteen has a TRS system but only is for ISCG or Threaded BB

Same with Srams Truvativ system it seems.

Does anyone know of any company that makes something like those or a PF BB?
