The 2018–2020 Tarmac: disc-era race geometry before SL7's aero integration. Still a low, racy fit; cockpit is more conventional than SL7/SL8.
Riders on used SL6s or comparing a previous Tarmac to SL7/SL8. Check stack/reach — sizes did not stay still. The S-Works kit is the halo build — same geometry as the non-S-Works page for this year, different parts.
