Threaded Shallow Cone Cup
The Threaded Shallow Cone Cup is for ROCK AND ROLL TRAINER USE ONLY. This cone cup replaces the the threaded cone cup on pre-2013 Rock and Roll trainers and is the mounting solution for Trek Speed Concept frames requiring a smaller outside diameter cone cup on the drive side of the trainer than the pre-installed cone cup. While the Standard Cone Cup (pre-installed on trainers manufactured after December of 2009)* will fit into the speed concept carbon frames, it does rub on the drive side. So, making a cone cup that has a smaller outside diameter fits better and prevents the carbon from getting marred.
*The Standard Cone Cup will fit the aluminum framed Speed Concept series bicycles, but we recommend using this specially-machined cone cup on carbon-series bikes. The Threaded Shallow Cone Cup will clear the frame flange and not mar the carbon. Use this cone cup on the drive side (side with chain) of the Rock And Roll trainer. Replace only the drive side cone cup on the trainer. It is not necessary to replace both cone cups.
