Specialized Tarmac SL8 Frameset Description:
The Specialized Tarmac SL8 Frameset is designed for speed across any ride profile. Building upon the SL7’s “one bike to rule them all” mantra, the Tarmac SL8 takes this all-around winning design and shaves weight while prioritizing aerodynamics and stiffness. This 1.69 kg (size 56cm) frame is made from FACT 10r Carbon. While slightly heavier than its S-Works counterpart (around 320g heavier), the SL8 frame provides the same level of compliance as its big sibling. The “Speed Sniffer” front design sets the headtube back away from the bike’s leading edge, improving the aerodynamics along the leading edge of the bike. Regarding its stiffness-to-weight ratio, the SL8 provides a 33% gain over the SL7, making this bike equally suitable for crushing the local crit races or a blistering uphill sprint finish. The SL8 is a winning formula designed to take on the most competitive races in the world.
Features:
- Aero In Everything design prioritizes aerodynamics in every element of the frame design
- The “Speed Sniffer” sets the headtube back and creates a sharper edge and lower drag shape
- Lighter than the SL7 while remaining super stiff (33% increase in stiffness-to-weight ratio)
- S-Works Tarmac SL8 FACT carbon seatpost is narrower and more aero
- 32mm tire clearance allows riders to run wider road tires
- The threaded BSA bottom bracket compatibility provides easy maintenance and is less likely to develop creaking noises
- Only compatible with electronically shifted drivetrains, such as Shimano Di2 and SRAM AXS
