It's crafted from our highest-level 900 Series OCLV Carbon that's not only insanely light, but delivers aerodynamic shapes for crushing descents and straightaways. Lightweight IsoFlow frame technology means Madone doesn't sacrifice comfort for speed. This build comes ready to win with a top-level SRAM RED AXS drivetrain, carbon wheels, a Trek Aero RSL one-piece carbon bar/stem, and RSL Aero Bottles and Cages for more drag reduction. - Revolutionary Full System Foil aero tube shapes redefine what fast looks like and help optimize aerodynamics around the whole bike - It's crafted from our highest-level 900 Series OCLV carbon that's mind-bogglingly light, 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 - New Blendr system on bar/stem makes it easy to add and remove a daytime running light
