Seller is asking for 750 and says:

Selling my Trek Domane AL 3 road bike (56 cm) The bike is in excellent mechanical condition and rides smoothly with no issues. It's been well maintained.

• Trek IsoSpeed carbon fork
• Shimano Sora 2×9 drivetrain
• Shimano Sora crankset
• Bontrager wheelset
• Continental Gatorskin puncture-resistant tires

Everything shifts and brakes as it should. The frame has a few small cosmetic marks from normal use but nothing that affects performance.
