2023 Trek Rail+ 9.9 XX1 AXS Gen 4

2023 Trek Rail+ 9.9 XX1 AXS Gen 4

The Rail 9.9 is our best long-travel electric mountain bike. You get an extra-beefy carbon frame, unbelievably smooth RockShox suspension, SRAM’s best wireless electronic drivetrain and a powerful Bosch smart system Performance Line CX motor with an extra-long range battery and the new Mini Remote. The new System Controller display sits almost flush with the top tube for a sleek look wherever you roll that stays out of the way when you’re riding hard.

Before using this vehicle, check the applicable local laws relating to your intended use of the vehicle on roads and road related areas.
