Specialized Tarmac SL7 Sport - Shimano 105
The Specialized Tarmac SL7 Sport is a carbon road bike for riders who want responsive handling, efficient climbing and aerodynamic performance without moving to an electronic drivetrain. Its FACT 9r carbon frame, Shimano 105 mechanical 12-speed groupset and hydraulic disc brakes create a dependable package for road racing, fast bunch rides, long-distance events and performance-focused training.
Lightweight FACT 9r Carbon Frame
The FACT 9r carbon frame has a claimed weight of approximately 1,010g, helping the Tarmac feel responsive when accelerating or climbing. Carbon construction also allows Specialized to balance stiffness with enough compliance to keep the bike manageable over longer rides.
Rider-First Engineered construction tunes the carbon lay-up and tube dimensions for each frame size, helping smaller and larger bikes retain consistent handling and ride characteristics.
Aerodynamics Without Excess Complexity
The Tarmac SL7 uses shapes developed through Specialized’s Win Tunnel testing to reduce aerodynamic drag without creating an unnecessarily heavy or complicated frame. This helps the bike maintain speed during racing, fast group rides and exposed road sections.
Clean cable routing gives the bike an integrated appearance while retaining compatibility with a conventional stem and separate handlebar. This makes cockpit adjustment, servicing and travel more straightforward than a fully integrated one-piece system.
Shimano 105 Mechanical 12-Speed
Shimano 105 mechanical shifting provides precise and dependable gear changes without batteries, charging or electronic setup. The 52/36T crankset and 11–34T cassette deliver a broad range for fast road riding, rolling terrain and longer climbs.
The traditional two-chainring drivetrain also provides smaller steps between commonly used gears, helping riders maintain a consistent cadence as speed and gradient change.
Confident Hydraulic Braking
Shimano 105 hydraulic disc brakes provide predictable speed control in wet or dry conditions. A 160mm front rotor supplies additional braking power where it is needed most, while the 140mm rear rotor keeps the system balanced.
Hydraulic operation requires less hand effort than cable-operated brakes, helping reduce fatigue and improve control on long or technical descents.
Practical DT Swiss Wheels
DT Swiss R470 Disc wheels provide a dependable foundation for training, racing and regular road riding. Their conventional construction makes ongoing servicing straightforward and provides a clear upgrade path if the rider later chooses a lighter or more aerodynamic wheelset.
Specialized Turbo Pro 700 x 26c tyres offer a fast-rolling setup suited to sealed roads, bunch riding and competitive use.

Our Thoughts on the Specialized Tarmac SL7 Sport
The Tarmac SL7 Sport gives you the speed and sharp handling the Tarmac is known for, without making the bike more complicated than it needs to be. The FACT 9r carbon frame feels responsive when you put the power down, while Shimano 105 mechanical shifting is reliable, easy to use and straightforward to maintain.
The 52/36T crankset and 11–34T cassette give you plenty of top-end speed, with a useful range for tackling climbs. Shimano 105 hydraulic disc brakes provide confident stopping power on fast descents and consistent braking when the weather turns.
The DT Swiss R470 wheels are dependable and well suited to everyday riding, although they would be the first place we’d look if you wanted to upgrade the bike later. Overall, the Tarmac SL7 Sport is a great option for riders who want a proper carbon performance road bike now, with plenty of potential to make it even better over time. The Tarmac's generous tyre clearance also gives riders the option of fitting wider tyres (up to 30mm-brand dependent) for improved comfort and confidence on rough New Zealand roads.

Geometry
The Tarmac uses a performance-focused road position, so frame size, handlebar width and stem length can all influence comfort and handling.
Contact Chain Reaction if you would like help comparing sizes or selecting a setup suited to racing, training or longer road events.
Size Guide
Rider height is a useful starting point, but body proportions, flexibility and preferred riding position can influence the ideal frame size. Riders prioritising racing may prefer a lower and more compact position, while long-distance riders may benefit from a slightly more relaxed setup.
Contact Chain Reaction for personalised sizing and bike-fit advice before ordering.
