Selling my Trek Madone SL6 Gen 8 with electronic Shimano 105 Di2 in frame size M. Original carbon wheelset from Bontrager: Aeolus Elite 35. Major service in summer 2026: retrofitted with TPU inner tubes. Rear tire replaced with Continental Grand Prix 5000 28mm. Bottom bracket replaced. Chain renewed. All drivetrain components degreased and switched to chain wax. Headset bearing will be replaced before sale. Everything will be checked again by a bike mechanic. Two small spacers were removed to lower the handlebar slightly. Can be converted back to original height before sale if needed. Minor signs of wear on crank and frame. No crash history. Test ride welcome. Original accessories are still available (e.g., tubeless setup). Bicycle will be sold without pedals and saddle bag. Garmin mount included if needed. Two spare tubes included.
