Carbon aero road bike Trek Madone SLR 7 AXS serpentine red: going wireless with Force AXS, 7.22 kg in ML

Trek Madone SLR 7 AXS Serpentine: going wireless with total peace of mind

The Trek Madone SLR 7 AXS Gen 8 is a carbon aero road bike in OCLV Series 900, built with wireless SRAM Force AXS E1 2x12 with power meter and Aeolus Pro 51 wheels, for 7.22 kg in size ML. It is a great gateway for the rider leaving a cable-operated drivetrain behind and discovering electronic shifting. Its Serpentine colourway fades from a dark, almost burgundy red to a brighter red.

Technical specifications

Who is it for?

For the experienced rider who has spent years on a mechanical drivetrain and is taking the leap to wireless and a high-end frame. It also suits the cyclist discovering power-based training who wants a complete bike, with nothing to add.

The LVR workshop view

OCLV carbon, Trek's signature. Since 1992, Trek has compacted its fibres under heat and pressure to eliminate micro-voids. The higher the series, the more material the engineers can remove without losing stiffness: the Series 900 chosen for the Madone SLR 7 AXS is 3D-moulded, with fewer fibre overlaps, and is up to 20 % stronger than OCLV 800. The painted frame weighs 796 g in ML and the fork 350 g, with Trek's lifetime warranty included.

Put simply: the Madone SLR 7 AXS pairs Trek's cutting-edge frame with a SRAM drivetrain that measures your watts straight out of the box. Compared with the Shimano SLR 7, it claims 300 g less and easier gearing; all it lacks compared with the SLR 9 AXS are the RSL wheels and the RED groupset.

The SRAM AXS logic is easy to learn: a paddle on the right moves the chain down to the smaller sprockets, on the left up to the larger ones, and pressing both together changes chainring. After two or three rides, most riders never look back, especially when they need to shift several gears at once when accelerating.

The SRAM Force hydraulic disc brakes modulate braking finely on the descents of the Minervois, with little effort at the lever, even with your hands on the drops. The SRAM AXS app lets you customise the paddles and check battery levels; we set it up with you at delivery.

Which Madone should you choose?

Our take: moving from a mechanical bike to this SLR 7 AXS means gaining wireless shifting, a power meter and a 796 g OCLV 900 frame. The SLR 7 with Shimano Ultegra Di2 will better suit someone who wants to keep Shimano ergonomics, at the cost of 300 g more.
