8 years after inventing the worlds first and best Standard Compression Systemª (SCSª), PROTO is proud to introduce the next generation of SCSª. The Sentinel SCSª is the most technically advanced Standard Compression Systemª ever created. Coming in at 3.5" tall, it offers a full 2" of handlebar support to accommodate the taller bars we are seeing become more prominent.
