We talked about it two weeks ago, a new Specialized Tarmac SL8 was seen in the paddocks of the Soudal-Quickstep formation. According to a technical document who leaked on the networkswe now know more on the future flagship of the American firm. Details.
At first glance, this new SL8 incorporates certain technical data from the SL7, such as the BSA standard threaded bottom bracket. But above all, and this was predictable given the size and profile of the steering tube, this new Tarmac is announced as more aerodynamic. All thanks to the new shape of the head tube and a new seat post. The relaxation of the UCI rules allows more latitude.
The technical document speaks of the FACT 10r carbon version and not of the S-Works model, surely in 12r. In fact, the module is announced at 1,690 g. Spe’ also announces 33% improvement in the stiffness/weight ratio and 6% for comfort (read below). With 7 sizes available, we stay on the same bases as the SL7.
Translated excerpts from the technical document
“Nothing is faster than the Tarmac SL8 thanks to a combination of aerodynamics, lightness and a ride quality previously considered impossible. After eight generations and over two decades of development, it’s the fastest Tarmac ever – it’s the fastest race bike.
• We put aero where it counts […] not just where it looks good. In the process, we created our most aerodynamic bike ever and more aerodynamic than the Venge. Airflow is optimized for maximum benefit with the new steerer tube – the Speed Sniffer. […] With a much sharper leading edge, providing much lower drag […] The Tarmac SL8 has the narrowest, most aerodynamic seatpost we’ve ever made to ensure the air around the legs flows faster.
• Massive gains in stiffness to weight ratio.
– a 33% improvement in the stiffness-to-weight ratio compared to the SL7; […] The Tarmac SL8 offers legendary handling, aggressive responsiveness and maintains proven geometry. The bike is stiffer at the bottom bracket, more precise on the handlebars, and combines with a new benchmark in comfort. Thanks to our Rider-First engineering, every rider, regardless of size, gets the same ride quality and handling. The Tarmac SL8 is 6% more comfortable […] with a unique feeling of flexibility […] . 32mm tire clearance is same as SL7 […] .
• 68mm threaded bottom bracket, flat mount disc brakes. »
