Trek Domane+ LT 9 Bike
Domane+ LT 9 is a high-end carbon drop-bar electric bike designed for roadies who want an authentic road bike experience with an extra boost. The sleek and efficient Fazua drive system kicks things up a notch when you need it—like riding into a headwind or beating your buddy up a climb—but doesn’t drag or hold you back when it’s not in use. You also get the high-performance benefits of Shimano’s best electronic drivetrain, Dura-Ace Di2.

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
