Manufacturer reports a 33% stiffness-to-weight improvement over Tarmac SL7, with greater pedal stiffness and bar precision; comparative manufacturer result without a fully public protocol
The earlier official mainland China source records a CNY 30,990 list-price reference; the 2026-09-24 exact China page response showed the model title but no current price or checkout data. The 7.68 kg size-56 reference and 33% stiffness-to-weight claim come from the U.S. product page and remain regional manufacturer claims. Stock, final checkout and the full comparative test protocol remain unpublished.
road.cc's review of the cheapest Specialized Tarmac SL8 with 105 Di2, compared with the S-Works version.
road.cc · 2025-12-09. Publication review; the video carries a Magene power-meter sponsorship. The entry Tarmac SL8 reviewed uses the same FACT 10r frame and 105 Di2 as the candidate; trim naming varies by market.Grundlage der Offenlegung.
Kernpunkte
Fahreindruck0:39The FACT 10r frame is less stiff than the S-Works but still reactive, and the reviewer prefers it for comfort; it does not ride like its weight.
Passungstest1:21Bars are too wide across the size range (40 cm on a 52, 42 cm on a 54) and cranks long (172.5 mm on a 54), which he calls old-school fitting for an aero bike.
Aufbauhinweis2:48Positives: most of the S-Works aero shapes and geometry, brass spoke nipples and an excellent 105 Di2 groupset with wide gearing.
Gemessen4:11The size-52 bike weighed 7.9 kg, more than the advertised figure for a 56; narrow rims and 26 mm tires hold back comfort and should be upgraded first.

A shop walkaround and weigh-in of the 2026 US Specialized Tarmac SL8 Comp before customer upgrades.
GC Performance · 2025-08-13. GC Performance is a bike shop that sold this bike to a customer; the 2026 US Comp shown has SRAM Rival AXS rather than the candidate's 105 Di2 on the same FACT 10r frame.Grundlage der Offenlegung.
Kernpunkte
Gemessen0:00The size-50 2026 Comp weighed 7.68 kg with bar tape; it sold for US$4,500.
Gibt Herstellerangabe wieder1:27He notes the Comp uses the same FACT 10r frame sold as the Tarmac SL8 Pro frameset at US$3,500, with comfort features borrowed from the Aethos such as thin seatstays and seatpost.
Passungstest5:52Clearance is 32 mm, but the bike ships with 26 mm tires on DT Swiss R470 alloy wheels, and a size 54 gets a 40 cm alloy bar on an SL7 stem.

An August 2025 six-month review of a Tarmac SL8 Pro with Ultegra Di2 on the SL8 frame that, below S-Works, uses FACT 10r carbon like the Comp recorded here. It covers the range structure, ride, fit and reliability; the Pro's groupset, wheels, one-piece cockpit and price differ from the Comp 105 Di2.

Kernpunkte
Preis bei Veröffentlichung0:44The Pro with Ultegra Di2 cost just over £8,000 at publication, £4,000 less than the S-Works he rode the year before.
Fahreindruck1:34Around his test track it was not as fast as a Canyon Aeroad or BMC Teammachine R, but in the same company as a Van Rysel or SEKA Spear.
Aufbauhinweis2:41In his UK range the S-Works, Pro and Expert share the frame design, tube shapes and aero profile; only the S-Works gets a lighter carbon lay-up, about 6.7 kg built against roughly 7.2 kg for the Pro tested.
Fahreindruck7:55Low weight, stiffness, steep angles and a short wheelbase gave it a lively, whippy feel on climbs, yet it stayed comfortable enough for 100-mile rides on rough roads.
Passungstest9:08The Pro's one-piece bar was 42 cm wide on his size 56, and Specialized's website offered no bar-width or stem-length choice; he would pick the Expert, which has the same frame and a two-piece bar and stem.
Verarbeitung und Mängel11:27After six months in all weathers he reported no issues: shifting never needed indexing, and brakes, bottom bracket, hubs and headset were still smooth.
