3/28/18: The red limit stop should be removed and discarded (Fig 3.5) at install of ICG IC4, IC5, IC6 Bikes as shown in the ICG IC4, IC5, IC6 Bike Setup Guide SB-33
Note: this only applies to product prior to August 2021.

The end cap part 190-01-00041-01 should then be fitted in its place (using the same bolt that was holding the RED limit stop in place). The end cap has a long plastic insert attached (Fig 3.6) which helps stop the Computer cable 170-01-00019-01 from being damaged.
