Tarmac SL8
Algupära
Tarmac SL8 turuletoomine toimus 2023. aasta meeste maanteesõidu päeval UCI maailmameistrivõistlustel Glasgow's — Specializedi teravmeelne vastus SL7 ühele nõrkusele, milleks oli see, et eelmine Tarmacu põlvkond oli tegelikult aeglasem kui lõpetatud Venge aeroratas. SL8-ga väitis Specialized, et see on kiireim tootmismaanteeratas, mida nad kunagi ehitanud on: 685g suurus 56 S-Works raam, ümberkujundatud 'Speed Sniffer' nina kitsama peatoruga, kitsam istmetoru ja langetatud istmetugi, mis kõik koos teevad selle kiiremaks kui Venge, jäigemaks ja kergemaks kui SL7 ning kuidagi ka mugavamaks. SL8 mattis tõhusalt Specializedi eraldi aerokategooria igaveseks — Venge't enam pole, pole ka 'ronimise vs. aero' valikut, vaid üks platvorm, mis on mõeldud kõige tegemiseks. Remco Evenepoel võitis 2023. aasta maailmameistrivõistluste maanteesõidu eeltootmise SL8-ga, mis on selline debüüt, mis lukustab mudeli WorldTouri tippu põlvkonnaks.

- Vedrustus
- Rigid — no suspension. Vertical compliance comes from the round 27.2 mm seatpost and frame layup (Specialized claims ~6% more compliant than SL7).

- Sadul
- S-Works: Specialized S-Works Power with Mirror (3D-printed). Lower trims: Body Geometry Power / Power Sport saddle on alloy rails.
- Geomeetria
- Aggressive race geometry, identical across all trims per size. 7 sizes (44-61 cm). Size 56: 73.5° head angle, 395 mm reach, 562 mm stack, 410 mm chainstays, 996 mm wheelbase, 72 mm BB drop. Same geometry as Tarmac SL7.
- Kaal
- S-Works complete ~6.7-6.8 kg (SRAM Red / Dura-Ace, 56 cm). Pro ~7.3-7.4 kg, Expert ~7.7 kg, Comp ~7.9 kg, Sport ~8.1 kg. Frame 685 g (12r, 56), fork ~358 g.
Verdikt
- True one-bike race platform: climber-light yet aero — 685 g S-Works frame and ~6.7-6.8 kg complete build, while ~16.6 s faster over 40 km than the SL7
- Race-proven at the highest level — Remco Evenepoel (Soudal Quick-Step) and Bora-Hansgrohe debuted and won on it at the 2023 Worlds and Tour de France
- 32 mm tire clearance plus round 27.2 mm seatpost gives genuine all-road versatility and comfort unusual for a pure race bike
- Roval Rapide CLX II 51/60 mm wheels are widely praised — aero depth that still climbs well
- Threaded BSA bottom bracket is service-friendly and resists the creak of press-fit designs
- Very expensive — S-Works trims reach €13-14k, top bracket even among flagship race bikes
- Disc-brake and electronic-shifting only across the whole range; no mechanical or rim-brake option even at entry trims
- Roval Rapide one-piece cockpit (S-Works/Pro) uses proprietary integrated headset bearings — replacements are dealer-only and limit fit adjustment
- Hookless tubeless rims restrict tire choice to approved models and cap pressure at ~73 psi / 5 bar
- Pro (FACT 10r) to S-Works (12r) jump is mostly frame weight and wheelset — reviewers question the €4-5k value delta
