The Madone SL 5 Gen 8 is a lightweight aero road bike that brings elite racing tech to a lower price point. It offers similar aero benefits to the pricier Madone SLR Gen 8, but with a more economical OCLV 500 Carbon lay-up and two-piece cockpit with hidden cable routing. It's built to race, with geometry that keeps you quick on the sprints yet in control on fast descents. A Shimano 105 group set keeps the price down while still delivering clean mechanical shifting you can trust.The Madone SL 6 offers legendary speed, cutting-edge tech and unbelievable ride quality in a 500 Series OCLV Carbon package that keeps things light and quick for fast road rides and races. IsoFlow technology smooths out bumps in the road while lowering weight and offering an aerodynamic advantage over your competition, and a wealth of super-speedy features like our newest Kammtail aero shapes, an economical Shimano 105 Di2 electronic drivetrain, carbon wheels and invisible hose routing make for a race machine that feels just as fast as it looks.
You want a featherweight road race bike without top-end race pricing. You're up for racing, club rides or solo spins up winding canyons, and don't want to compromise between climbing efficiency and aerodynamics. You're happy with more economical components that help you get on your dream bike faster.
An ultra-light OCLV 500 Carbon frame with aero tubing and IsoFlow comfort technology. A 2x12 Shimano 105 group set that delivers clean mechanical shifts without the faff of electronic group sets. Tubeless wheels that help fight punctures while reducing rolling resistance, and hydraulic disc brakes.
The Madone SL 5 Gen 8 is the perfect bike for someone looking for superbike performance at a lower price point. It offers the same frame tech as its SLR sibling, like aero tube shaping and lightweight IsoFlow comfort tech, but with a more economical build that leaves budget to spare for race entry fees and bike trips.

To measure your height, stand up straight, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.
How to measure: Stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to the ground to find your inside leg measurement. Your inside leg is very important to your final bike size so please measure carefully.
