Specialized S-Works Transition, is a fast and efficient triathlon/time trial bike with the proven E5 Aerotec alloy aero frame. This one’s lightweight, stiff, and built to slice through the wind, making it a great choice whether you’re training hard or lining up on race day.
It’s built with a 2x10 speed Shimano drivetrain: compact FSA 50/34t crank, 11–28t cassette, Shimano 105 front and rear derailleurs, bar-end 10sp shifters. Stopping power comes from 105 caliper brakes paired with 3T aero levers.
Wheels are Easton Velomax aero profile 700c clinchers, spinning smooth and true. Up front is a Zipp tri-bar cockpit for proper aero positioning, and the saddle is a Specialized Romin Evo Expert — comfortable and supportive for long efforts.
The S-Works Transition was one of the most respected aero frames of its time and still holds its own as a seriously fast and well-designed tri bike.
52cm fits riders around 5’7″ to 5’10″ comfortably — good reach with tri bars, and frame geometry that supports both upright training or full aero stance.
I collect and restore vintage bikes and I return gently used bikes to like new condition. Please check out my instagram page - sfbikemarket. I also offer tuneups and repairs for the bikes I sell. Additionally, I know how to properly tune up, maintain and repair Campagnolo / Campy equipped bikes, and have parts for them.
