CST C979 Tire – 700c × 35mm

CST C979 Tire – 700c × 35mm

The CST C979 is a comfort-oriented urban tire designed for 700c wheels with a focus on low rolling resistance and puncture protection. Featuring a directional grooved semi-slick tread pattern with textured shoulders, this tire delivers fast rolling on straightaways while maintaining cornering grip for city riding and commuting. The 35mm width provides cushioning over rough pavement and potholes while the good tread depth adds puncture resistance for reliable urban transportation.

Key Features

• Directional Grooved Semi-Slick Tread – Center tread features shallow grooves in a semi-slick pattern for minimal rolling resistance on pavement; directional design optimizes forward traction
• Textured Shoulders – Side tread transitions to more aggressive texture for improved grip when cornering or navigating turns at speed
• Good Tread Depth for Puncture Protection – Substantial rubber thickness between the road surface and casing reduces puncture risk from glass, debris, and sharp objects common in urban environments
• 35mm Width – Mid-width profile balances speed with comfort; wider than narrow road tires but narrower than mountain bike tires, providing cushioning over rough pavement without excessive rolling resistance
• Comfort-Oriented Design – Engineered for urban riding where comfort, puncture resistance, and reasonable speed matter more than maximum performance

Compatibility and Ideal Use Cases

This tire fits 700c wheels with adequate frame and fork clearance for 35mm width (typically hybrid bikes, touring bikes, commuters, and some cyclocross bikes). Requires an inner tube (sold separately). Best suited for urban commuters, city riders, and touring cyclists who need a tire that handles pavement efficiently while providing puncture protection and comfort over imperfect road surfaces. The semi-slick tread makes this tire fast on smooth roads while the textured shoulders provide confidence when cornering on bike paths or navigating city traffic. The 35mm width offers enough cushioning to smooth out potholes, expansion joints, and rough pavement without the sluggish feel of wider tires. Not recommended for off-road riding, gravel, or mountain biking where more aggressive tread patterns are needed. Ideal for riders prioritizing reliable transportation, comfort, and puncture resistance over absolute minimum weight or maximum speed.
