Cozy Beehive said:In other words, you're saying that Cassani said that this is a Gruber Assist and that the pro version is much more silent than the retail one?
Please clarify. I want to know what Cassani really said.
Cassani didn't say that the bike showed is powered by Gruber Assist. But they started the bikes' engine in the video and I could not hear the loud and annoying noise that the Gruber Assist makes. So it is my assumption that this is a more advanced and enhanced pro version that seems to be more silent.
Cassani only said that the bike he showed us has been in use since 2004 and has been used by several pro riders according to his source.
Hope this clarifies any misunderstandings.
