Silca Protocol RCR Road Tyre

The tyres we wanted to ride didn’t exist.

Years of studying tyre pressure, rolling resistance, aerodynamics, vibration losses, rim width, sealant, valves, rim tape, and TPU tubes taught us that a modern race tyre is more than tread and rubber. It’s part of a complete tyre system where every engineering decision affects performance. We weren’t looking to make another tyre. We were looking to build the tyres we wanted to ride. Tyres designed around the conditions we race, the widths we believe modern riders need, and the performance characteristics we value most.

That’s PROTOCOL.

Protocol RCR

Protocol RCR applies the same engineering philosophy found throughout the Protocol family, balancing rolling efficiency, grip, ride quality, durability, and modern tyre system compatibility for today’s road and all-road race conditions.

Optimised for:

• Modern road and all-road race conditions

Protocol RCR Technologies

Pulsar Compound

Hi-performance rubber/silica race compound engineered to balance rolling efficiency, grip, and durability.

Race Casing

High-performance casing architecutre developed around modern tyre pressures.

CarbonBead BeadLock

Carbon fibre bead technology that maintains dimensional stability throughout the life of the tyre.

RCR Specifications

Dimensional Reference

Measured tyre width is based on a 25 mm internal rim width and recorded 24 hours after installation. Actual installed width will vary with rim dimensions.

Specification 

• 29, 34, 38mm options
• 290g in 29mm, 320g in 34mm, 350g in 38mm
• 120 TPI
• SealSkin Tread Protection
• Fastest Pulsar compound
• Width as measured on a 25mm rim after 24 hours
• Designed for race conditions

RCR Architecture

A volume-centric approach that prioritizes width and speed without adding useless bulk, built around lower pressures associated with modern ride rims. It is the first road tire in this size range designed and optimized with the same care as a racing tire, thinner, faster, and more supple.

Performance Data

Against the Vittoria Corsa Pro Control 38mm, the RCR rolled at 31.7 watts in controlled lab testing versus the Vittoria's 40.5, saving nearly nine watts at the same width. It does it 70 grams lighter per tire, which is 140 grams off the wheels on a pair.

Ideal Conditions

From local criteriums to the punishing cobbles of Paris-Roubaix. The increased air volume absorbs impacts and reduces flat risk, making it the answer for rough pavement and long days where comfort holds your speed together.
