SILCA Protocol RCG-1 Gravel Tyre – 700 × 45 mm

Fast Gravel. Confident Control.

The SILCA Protocol RCG-1 combines the fast rolling feel of a hardpack slick with the comfort and control of a high-volume XC race tyre. Designed for riders who want outright gravel speed without sacrificing cornering confidence, it is equally capable on race day or fast mixed-surface adventures.

The 45 mm RCG-1 is an ideal gravel tyre for riding around Noosa and the Sunshine Coast. Local routes frequently transition between tarmac, hardpacked gravel, forest trails and loose-over-hard surfaces — exactly the conditions this tyre is designed to handle.

Its low, ramped centre tread reduces rolling resistance and maintains speed across sealed roads and smooth gravel. When braking, the directional tread provides additional bite. Lean the bike into a loose or high-speed sweeping corner and the elevated side knobs engage, creating a larger contact area for dependable grip and stability.

This combination makes the RCG-1 particularly well suited to fast rides through the Noosa Hinterland and selected sections of the Noosa Biosphere Trails. The network connects hinterland areas including Cooroy, Pomona, Cooran and Kin Kin, with varied terrain that rewards a tyre capable of rolling quickly while remaining composed when the surface changes.

At 45 mm wide, the RCG-1 provides enough volume to smooth out rough gravel and maintain traction at lower pressures, without losing the responsive character of a race-focused tyre.

Available from Venture Cycles Noosa, the RCG-1 is a standout choice for Sunshine Coast gravel riders chasing speed, comfort and control.
