Since the BB on these bikes were close to the tubes that is possible on this bike. What remains to be seen is whether there was a way of pushing grease to the outside in that particular bike. I have no idea if the concept could work, buy maybe? It was likely a mod based on the WTB flushable systems of the late 80s.
