Madone SL 5 Gen 8

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 groupset that delivers clean mechanical shifts without the faff of electronic groupsets. Tubeless wheels that help fight punctures while reducing rolling resistance, and hydraulic disc brakes.

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.

Revolutionary Full System Foil aero tube shapes redefine what fast looks like and help optimize aerodynamics around the whole bike
A more economical 500 Series OCLV Carbon frame and new tube shaping shave weight where it matters most to help you fly up climbs
You get clean and reliable shifting without breaking the bank with Shimano's workhorse groupset – 105
Lightweight, race-focused IsoFlow comfort tech helps you ride stronger longer without sacrificing weight or aerodynamics

"Faster than previous Madone...how can a bike this fast be this comfortable?"

"This feathery wind-cheater is just the bike I need for all my road rides."

We reserve the right to make changes to the product information contained on this site at any time without notice, including with respect to equipment, specifications, models, colors, materials, and pricing. Due to supply chain issues, compatible parts may be substituted at any time without notice. Prices shown are manufacturer's suggested retail prices.

Bike and frame weights are based off pre-production painted frames at time of publication. Weights may vary in final production.

How tall are you?

To measure your height, stand straight up, 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.

What is your inseam?

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 inseam measurement. Your inseam is very important to your final bike size so please measure carefully.
