The youngest of the compression system family. It came to life as a result of impossibility to use standard ICS with CrMo/steel bars. CrMo is a hard material and the starnut (from ICS) can hardly "bite" into it.
HIC can only be used with bars of 32 mm (inner diameter).
Advantages
- The bars can be easily replaced/swapped for other bars without the necessity to remove the front wheel or strip down the headset
- The bottom part of HIC is always flat so there is no risk of damaging the headset bearings
