The Tarmac SL9 was born from a simple premise: the only number that matters at the finish is time. Drawing on Win Tunnel research and the sixth-generation Moving Leg Mannequin airflow work that shaped its S-Works sibling, Specialized re-sculpted every tube for real-world speed rather than wind-tunnel bragging rights. This Expert build brings that platform down to a FACT 10r carbon frame paired with SRAM's Force AXS groupset, offered in Gloss Silver Dust/Lime and Satin Warm Smoke Metallic.

The frame carries Rider First Engineered construction, meaning each size receives its own layup so a 49 and a 61 handle with the same intended balance of stiffness and compliance. Geometry is shared across the Tarmac line and remains race-oriented: a size 56 pairs a 570mm top tube and 392mm reach with 410mm chainstays and a 72mm bottom bracket drop, producing a stretched, planted position that rewards a rider who wants to hold speed in a bunch. Clearance runs to 32mm tires, and the frame ships on 30mm rubber to take advantage of it.

The construction details matter for a bike meant to be lived with as much as raced. A threaded BSA bottom bracket keeps servicing straightforward, the UDH dropout standardizes rear derailleur hanger replacement, and the 12x142mm rear and 12x100mm front thru-axles with flat-mount disc mounts follow current road standards. This is a race chassis without the maintenance headaches that once came attached to that category.... Read More
