Specialized’s S-WorksTarmac SL7 Disc Road Frameset is designed to meet the needs of every serious racer or rider, one who doesn’t want to compromise between speed, weight and handling. The aim was to combine the best of the Venge and the Tarmac, and the SL7 won’t disappoint. Ready to be built up into your dream bike, the frame is constructed from FACT 12r Carbon that, in a top-spec build, will keep weight down to the UCI limit. Tubing shapes have been created and optimized using the FreeFoil Shape Library and tested in the Win Tunnel, ensuring this is by far the fastest Tarmac to date, when climbing and descending.
Proven Performance Road Geometry has been retained, as has the Rider-First Engineered™ philosophy, which ensures all frame sizes benefit from the same incredible ride feel. The SL7 can be built up with either mechanical or electronic components, and all cables route internally for sleek integration. Alongside all the innovation and technology incorporated into this frameset, it’s available in a range of striking, head-turning colorways.
The latest Tarmac combines the handling and low weight of the Tarmac with the aerodynamics and integration of the Venge, so there are no compromises
Designed using the FreeFoil Shape Library and the Win Tunnel, Specialized has created their fastest ever Tarmac
Rider-First Engineered™ design ensures the most balanced, best handling Tarmac yet, no matter the frame size
The new Tarmac utilizes simple integration for a clean, fast cockpit
Fully internal cable routing for mechanical and electronic shifting, whether you’re using the Tarmac integrated stem or a traditional stem and round bars
Same proven geometry as the SL6 Tarmac
Threaded bottom bracket design
Includes Specialized 2021 S-Works Tarmac FACT Carbon seat post and integrated 6-degree stem
At 23:00 on July 28, 2020, Specialized Lightning officially released the Tarmac SL7 road bike. News about the Tarmac SL7 was actually spread as early as May this year, when a rider took a picture of the new SL7 leaning against a tree on the side of the road, sparking a clamor, and each rider had mixed feelings about it. From the SL7 officially released by Lightning this time, the spy photos that were rumored earlier are indeed the actual car, and a few days ago, Wildway.com also found the virtual reality technology version of the SL7 on the opening screen interface of Specialized Ride App, and the details are also very much in place.
So, are there any other points worth being noticed in this lightning release of the SL7? Let’s continue to look down.

So, are there any other points worth being noticed in this Specialized release of the SL7? Let’s continue to look down.
For Specialized, the Tarmac is ultimately a blend of the Venge’s aerodynamic appearance and the Tarmac’s weight advantage, and this is obviously a must for the hardness requirements of the sprint.
Specialized says the size 56 Tarmac SL7 with front derailleur bracket weighs 800 grams in a painted frame, and if you want to use just the single disc, you can lose about 15 grams by removing the front derailleur bracket.
As mentioned in the previous article, the AR version of the SL7 appears to have switched to a five-way spec, but in fact the Specialized really has switched to a threaded BSA five-way, so it’s lighter and allows for metal inserts to be glued into the frame, while the SL6 uses an OSBB press-in five-way. If the Aerofly II handlebar set is used, the weight will be reduced by another 45 grams, and the internal cable routing will be made easier.
The S-Works frame uses Specialized’s top-of-the-line FACT 12R carbon fiber, while the others are FACT 10R, but weighs just 120 grams more, which is 40 grams lighter than the previous FACT 10R SL6. The green S-Works SL7 Di2 weighs 6.7kg, the Tarmac SL7 Pro UT Di2 weighs 7.3kg, and the Expert UT Di2 weighs 7.65kg.
Specialized officials also said that compared to the SL6, the new SL7 can spend 45 seconds less in the 40km time trial. But Specialized did not elaborate on the details of the frame’s aero design, but only on the whole bike, and especially emphasized that the aero test model was paired with the Roval Rapide CLX wheelset and Aerofly II gripset. In addition, the rear upper fork tee design is also borrowed from the Venge.
This results in a thinner seat post, which also means that the Di2 junction box can only be located at the top of the seat post, within a wider section below the cushion clamping area.
The Aerofly II grips are only available on the first four models from the top version on down. It hides all the cable tubes inside and directs them toward the handlebar, and the brake hoses are extended straight back into the head tube, but the handlebars have such a large Reach value that it’s not generally acceptable. If you buy a frameset and want to use mechanical shifting, the Specialized also comes with a separate wrist-set top cover with holes for inserting the cable tubes.
Interestingly, Specialized says the Tarmac SL7 has an updated profile for the head tube, seat tube, fork legs and seat post, but not the downtube. They also say that many brands offer a lot of bold designs for downtube shapes, but the performance trade-offs in making the downtube more aerodynamic don’t mask the added weight and the reduced quality of overall handling and riding comfort.
Comparing the frame geometries of the three different sizes, the only significant difference can be found in the Stack. the SL7 is 10mm lower relative to the SL6’s Stack, but because the SL7 has a higher wrist group cover position, it rides the bike in the same position as the SL6 while using the same number of spacers.
So it can be said that the SL7 is on the SL6, changing the geometry of the upper part of the frame to improve riding comfort and performance, as well as the Specialized expression of the entire frame stiffness, smoothness and flexibility from front to back more balanced. However, the fit of the rear wheel is not as great as expected, and is the aerodynamic effect in the real world really as good as the official representation?
How is the Tarmac SL7 different from the SL6 and Venge?
At first glance, the new SL7 doesn’t look too different from the SL6 it replaces, and it’s very similar to the latest Venge. But it’s important to note that the SL7 essentially replaces the Venge, so Specialized will likely only offer the Venge frameset in select markets in the future.
The Tarmac SL6 offers a performance design without the aerodynamic and lightweight features of the design. the SL7 is lighter than the S-Works FACT 11r Venge and essentially has its aerodynamic characteristics. In addition the SL7 switched to a BSA threaded five-way, eliminating the need for a press-in OSBB, which means Specialized’s former carbon fiber Power discs are no longer compatible, but instead use their S-Works Power Pod instead, making it usable on Dura-Ace cranks and matching the 4iiii labeled power meter.
The SL6 seatpost is a round seatpost with the cables entering the frame from the front of the downtube, while the SL7 has a better aero shape and hides all alignments from the wristset.
At the time of the Tarmac SL7’s release, Specialized also offered a Peter Sagan limited edition, with only 300 units produced worldwide, which came with a Shimano Dura-Ace kit, a custom Rapide CLX decal wheelset and a black and gold paint job.
