Really quick as well, there has been an update on the official American Speedster website. The Gulf Coaster has been replaced with the new
Slick Rock Camp CycleThere's a
video here from Dan, the creator of American Speedster, himself. This was a concept for a while, and it looks like it's going to be put into production.
To sum this down to what it is, it's a compact version of the Sidekick, but instead, with 2 derailleurs to shift the bike and its chain. In theory, using a 6 speed sprocket, and 2 respective shifters, it should be a 12-speed. This will then be faster than the Sidekick in-game.
Because of this change, I'm canceling the Gulf Coaster project, and replacing it with this new bike.
