Specialized Tarmac Sl7 Sport - Shimano 105 12-Speed - Text Review

The Tarmac SL7 features a FACT 9r carbon frame with Rider-First Engineered construction. The design aims to deliver balanced handling across different frame sizes. Its aerodynamic tube shaping comes from Specialized's Win Tunnel development approach. Clean cable routing creates a sleek and modern appearance while keeping the cockpit uncluttered. The threaded bottom bracket and thru-axle construction provide a practical and secure platform. Overall, the frame combines aerodynamic efficiency, lightweight construction and responsive road handling.

The Shimano 105 mechanical 12-speed drivetrain is one of the Tarmac's key strengths. The 52-36T crankset is paired with an 11-34T cassette to provide useful gearing for both fast roads and climbs. The Shimano 105 rear derailleur delivers precise mechanical shifting across the 12-speed cassette. The two-chainring setup provides a broad overall range for varied road conditions. The Shimano SLX M7100 12-speed chain completes the drivetrain. This combination makes the Tarmac suitable for both competitive riding and demanding training sessions.

Despite its race-focused character, the Tarmac is designed to provide a controlled ride over longer distances. The FACT carbon fork helps manage road vibration while maintaining accurate steering. The Body Geometry Power Sport saddle is designed around rider comfort and support. Supacaz Super Sticky Kush bar tape adds cushioning and grip at the hands. The 700x26 Turbo Pro tires maintain the bike's fast road-focused character. Together, these components create a performance-oriented setup that can still handle longer road rides comfortably.

Shimano 105 hydraulic disc brakes provide strong and predictable braking performance. The bike uses a 160mm front rotor and 140mm rear rotor for balanced stopping control. The Specialized Shallow Drop handlebar provides a performance-oriented riding position. Its integrated 6-degree stem creates a clean and aerodynamic front-end appearance. The responsive steering is well suited to fast cornering and competitive road riding. Together, the braking and cockpit setup give the Tarmac confident control when riding at high speeds.

The Tarmac uses DT R470 Disc wheels paired with Specialized Turbo Pro 700x26 tires. The wheel setup is designed around efficient road performance and dependable handling. The narrow tires help maintain the bike's fast and aerodynamic character. The Body Geometry Power Sport saddle uses steel rails and provides a supportive platform for performance riding. The sealed-bearing wheel system contributes to smooth rolling performance. Overall, the wheel and saddle combination keeps the bike focused on efficient road speed.
