Trek Madone SLR 7 Project One, Tri/TT Ready w/ Power Meter & Swiss Side Wheels

Selling my heavily upgraded, custom-built Trek Madone SLR Project One. (Size 56)

It features a jaw-dropping custom iridescent color-shifting paint job from Trek’s Project One studio that looks incredible in the sunlight.

Condition: Meticulously maintained, recently serviced, minor cosmetic scuffs as seen in photos. Never crashed.

Price: €3500
(Open to swap for a MTB e-bike of similar value)

Unlike a standard road setup, the drivetrain on this Madone is a very specific, custom Di2 electronic configuration geared for ultimate top-end speed and data tracking:

The Power: It features a massive Dura-Ace 55T drive-side crank for maximum flat-out speed, paired with an Ultegra non-drive side arm equipped with a Stages Left-Sided Power Meter so you can perfectly pace your TT or Tri efforts.

The Security: To handle that massive 55T ring, it utilizes an Ultegra Di2 front derailleur and a clutched GRX Di2 rear derailleur. The clutch keeps chain tension incredibly tight across the block, ensuring zero chain drop under heavy power.

Fully kitted out with deep-section Swiss Side aero wheels and a clip-on aero-bar setup, it's dialed in and ready to race on day one.
