Domane SLR Gen 4 Frameset

You're building up your dream endurance road bike for quickness and comfort during your longest days in the saddle, and you want to start with a light, comfort-focused OCLV Carbon Domane frame to get it done.

An ultralight and refined 800 Series OCLV Carbon frame with rear IsoSpeed, internal storage, internal cable routing, and top tube mounts. Domane SLR Disc Frameset is built for flat-mount disc brakes and includes a headset, 12mm thru axles, and a full carbon Domane Disc fork.

Domane SLR Gen 4 brings rear IsoSpeed to an 800 Series OCLV frame for a smooth, light, and ultra-comfortable ride on any road
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
Road-smoothing rear IsoSpeed absorbs fatiguing bumps in the road to keep you comfortable through the longest miles and hardest race days
Includes a bearing top cap compatible with Trek RCS stems. Already have a stem you love? No problem – a traditional bearing top cap is available separately.

"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.

Performance. Stability. Victory. Trek endurance geometry is a triple threat, maximizing control, handling, and responsiveness through perfectly tuned rider weight bias.

Additional tire clearance allows Domane to go where no road bike has gone before. Race, ride, explore.

All-new Flat Mount disc brakes are more elegant, lighter, smaller, and cleaner than traditional disc brakes, providing superior performance and stopping power under harsh conditions.

As befits the world’s most advanced endurance racing bikes, we’ve developed the world’s most stable racing geometry. Still racy, but with a slightly higher head tube for better stability and greater comfort through the entire ride.

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.
