This cone cup replaces the threaded cone cup on pre-2013 Rock and Roll trainers and is the mounting solution for carbon Trek Speed Concept frames that require a smaller cone cup on the drive side of the trainer than the pre-installed version. - Only compatible with the Rock and Roll trainer - This cone cup's smaller outside diameter fits makes it compatible with carbon Trek Speed Concept bikes (aluminum Speed Concept bikes are compatible with the Standard Cone Cup) - Use this cone cup on the drive-side of the Rock And Roll trainer (it is not necessary to replace both cone cups)
