TREK Madone SLR 9 AXS 1x Gen 8 Road Bike in Purple Phaze and Amethyst Marble

The Madone SLR 9 AXS 1x Gen 8 is Trek’s lightest and most aerodynamic race bike to date—engineered for maximum performance with zero excess. Weighing just 6.4 kg, it comes in 400 grams under the UCI minimum weight limit, giving you every possible advantage when climbing, sprinting, or chasing the breakaway.

Its featherlight 900 Series OCLV Carbon frame features Iso Flow technology to reduce drag and increase rider comfort, while the SRAM RED AXS 1x12 wireless drivetrain offers elite-level electronic shifting in a simplified, lightweight package. A set of ultralight Bontrager Aeolus RSL 37 carbon wheels and an aggressive Matte Deep Smoke finish complete this purebred race machine.

Key Features900 Series OCLV Carbon frame – Trek’s most advanced carbon lay-up delivers top-tier stiffness-to-weight and aero performance6.4 kg total weight – Sits 400 g under the UCI minimum, giving a distinct edge on steep climbs IsoFlow technology – Enhances aerodynamics while improving vertical compliance for rider comfortSRAM RED AXS 1x12 wireless drivetrain – Lightweight, precise shifting with fewer components Bontrager Aeolus RSL 37 carbon wheels – Ultra-responsive and aerodynamic Matte Deep Smoke finish – Sleek, modern, and built to race Why go 1x?Opting for a 1x drivetrain delivers tangible benefits—reduced weight, mechanical simplicity, and cleaner aerodynamics. With no front derailleur or second chainring, there's less to maintain and a more streamlined setup for racing.

The intuitive single-handed shifting allows for faster decision-making and a quieter, more efficient drivetrain. While 1x systems typically come with a wider cassette range (meaning slightly larger jumps between gears), most racers won’t notice the difference unless tackling extremely varied terrain.

For those who value low weight, minimal complexity, and pro-level performance, 1x is the clear choice.
