Domane SL Gen 4 Frameset

You're a performance-minded cyclist who craves comfort on a long day in the saddle without skimping on the speed. You want the freedom to let your mind wander and want to build up the perfect endurance road rig that's fast, comfortable, and versatile. You need a platform that earns top marks for tech with road-smoothing rear IsoSpeed.

A light and refined 500 Series OCLV Carbon frame with an internal storage compartment, stable Endurance Geometry, internal cable routing, fender mounts, and road-smoothing rear IsoSpeed. Designed for flat-mount disc brakes and includes a headset and a full carbon Domane disc fork. Added top tube mounts let you secure bags for longer rides without bulky straps and bungees.

Domane SL Disc Frameset is an ideal bike for long rides and races. It’s fast, stable, and rear IsoSpeed absorbs fatiguing bumps in the road so you can stay stronger longer.

Domane SL Gen 4's aero Kammtail tube shapes and rear IsoSpeed comfort technology come together for a super fast, light, and smooth ride
This bike is super versatile and equally suited to all-day adventures on the open road, club rides, and racing
Road-smoothing IsoSpeed and clearance for up to 38mm tires absorbs fatiguing bumps in the road for a smoother, more comfortable ride
A convenient internal storage compartment gives you a versatile spot to stow tools and gear, while top tube mounts let you cleanly bolt on a bag for all day adventures

"When you get on a bike that is fast, quick, and communicative but also floats and coddles the rider like a newborn baby, well, that is a special bike. And that is what the new Domane is: Special. A great bike made better. A bike for the modern road rider: Freaking fast, wonderfully comfortable, and oh so practical."

"The level of smoothness on the Domane continues to impress, creating an experience akin to being chauffered around in a luxury sedan. It absorbs all road vibrations, operates quietly, and accelerates on flats deceptively quickly…I'll be in for a rude awakening after returning to a road bike without IsoSpeed."

"I took the Domane on my local gravel and some select chunky bits to see how it would fare. The most notable transition from road to gravel was the sense of ease. Usually, when you roll from tarmac to stones, the bike can feel skittish and nervous (rider or bike). The Domane feels stable, and instead of holding your breath, you breathe out."

Whether you're riding solo, with a group, on smooth roads, or light gravel — here are the accessories you need to make sure your Domane is always ready.

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.
