Sram's latest red axs e1 ultra-light drivetrain and power meter for training with data. A universal derailleur hanger so you can get a replacement from anywhere. Plus, it's topped off with bontrager aeolus rsl 51 tubeless carbon wheels and a trek aero rsl one-piece bar/stem.

The madone slr 9 axs gen 8 is our lightest, most aero, top-performing madone that's ready to deliver superbike performance absolutely everywhere. It's crafted with a supremely light 900 series oclv carbon frame for rocketing up climbs, aero tube shaping for slicing through windy descents and isoflow comfort tech to keep you feeling good through it all. It's spec'd with the top components and doesn't make any compromises- the revolutionary full system foil aero tube shapes redefine what fast looks like and help optimise aerodynamics around the whole bike- it's crafted from our highest-level 900 series oclv carbon, which is mind-bogglingly light and stiff where you need the power, and compliant where you crave comfort- carbon wheels keep weight down and performance up, so you can crush climbs and soar down descents- you get precision shifting in sram's lightest package ever with red axs e1 wireless drivetrain, plus an ultra-precise power meter to get more from training days- rsl aero bottles and cages make the whole rider system faster to give you even more aerodynamic gains- a new blendr system on the bar/stem makes it easy to add and remove a daytime running light.

Redefining what fast looks like revolutionary new full system foil aero tube shapes improves airflow over the whole bike while maintaining the lightness climbers crave. Plus, the bike as a entire rider system was meticulously designed and rigorously tested to be faster everywhere. A 80% more vertically compliant isoflowwe refined our race-focused comfort tech to be lighter and have nearly double the vertical compliance so you can ride stronger for longer.

Designed for the world's best the madone slr gen 8 is raced and loved by lidl-trek's fastest sprinters and climbers and is the only bike they need for race day. One-piece aero rsl bar/stem is lighter, more aerodynamic and more ergonomic than the previous version. Plus, the hoods are 3 cm narrower than the drops so you can adjust your positioning to prioritise aerodynamics (in the hoods) or power (in the drops).Rsl aero bottles and cages were specifically designed along with the whole rider system to help make the madone even faster.
