Protocol RCG-4 Tubeless 700c Gravel Tire

The Silca Protocol RCG-4 is built for the days when gravel gets loose, muddy, sandy, and technical. Its aggressive tread uses fewer, larger knobs with generous spacing between them, allowing the tire to shed mud and loose dirt instead of packing up and losing traction.

The RCG-4 bridges the gap between gravel racing and mixed-trail riding, giving you the grip and control needed for everything from sloppy gravel roads and loose rock to singletrack and off-camber terrain. Full bead-to-bead SealSkin protection adds durability for the rocks and rough surfaces that come with riding beyond smooth gravel.

Who It's For
The Silca RCG-4 is for gravel riders who regularly venture beyond smooth hardpack and into mud, sand, loose rock, and rough mixed terrain. It's also a strong choice for gravel races and rides where conditions can deteriorate quickly and traction and durability matter more than having the fastest-rolling tread.
