The first few rides on the ONE, I kept looking down. There's a lot to look at. The cockpit is doing something I've never seen before, the fork is enormous, and the whole front end looks like it belongs on a futuristic concept bike. After the initial awe and amazement wore off, what surprised me the most is what happens when you stop looking down. The ONE feels like a bike. Fast, direct, and purposeful, but a bike nonetheless. And when you put the power down and the speeds begin to increase, you really begin to understand the bike's true intentions and where it thrives.
After 4 months with the ONE, the miles have begun to stack up and I feel like I’ve gotten to become quite acquainted with the bike. I've had it on long group rides, ridden up and down our climbs around Reno and Lake Tahoe, raced the Tuesday night crit series, and on a lot of regular training rides where nobody's watching. Not a closed Dauphiné stage. Reno roads, chip-seal, potholes, and all.
Optimized Race Geometry
Modern racers have been quietly rewriting their position for a few years now: saddles creeping forward, cranks getting shorter, bars narrowing, riders rotating further over the front wheel. Most frames were never built with that position in mind, so getting there usually meant fighting your setup: stacking spacers, slamming saddles, running stems long enough to feel sketchy at speed. Factor's pitch with the ONE is that none of that should be necessary. The geometry was built around where racers actually want to sit, not where a decade-old frame template assumes they should.
You feel that intention the moment you get into the drops. The reach is long, but it doesn't ask you to overextend or perch awkwardly to get there. It just puts you exactly where a long, low stem would, minus the twitchiness that usually comes with it. The front end stays planted and predictable even as you tip further forward, so there's none of that nervous, vague feeling some aggressive setups get at speed.
The lower bottom bracket is the quiet hero here. It drops your center of gravity right as everything else about the bike, shorter cranks, fatter tires, is trying to raise it, and the result is a bike that feels grounded rather than perched, especially at speed or leaned into a corner. The seat angle adjustability means you can keep dialing your position forward without ever feeling like you've outrun the frame's comfort zone.
What's most impressive is that getting low and aggressive on the ONE never feels like punishment. It feels natural, even progressive, the bike seems to invite you into that position rather than tolerate it. And once you're there, the payoff is obvious: this is a bike that rewards aggression. Get low, get forward, and the ONE stops feeling like something you're riding and starts feeling like something that's working with you to go very, very fast.
Aero You Can Feel
There's a point on the ONE where the bike stops feeling like something you're pushing through the air and starts feeling like something the air is pushing along with you. It shows up right around 20mph and gets more pronounced the faster you go: a sensation less like cutting through wind and more like catching it.
Factor's own test riders describe the same thing. One of their WorldTour pilots put it simply: it feels like the bike is helping you, not just cutting the air, but pulling you through it. Another noted a distinct "lift" sensation once he got the bike up around 30mph, the same speed range where Factor's wind tunnel data shows the ONE's advantage over its competitors actually widening rather than fading. A lot of aero bikes are fast in a straight line at low speed and then hit a wall as wind and yaw angles increase. The ONE does the opposite: the faster you go, and the more the wind comes at you from an angle, the more the bike seems to want to lean into it.
That's by design. Factor spent most of its engineering effort on managing airflow that's already moving, the turbulence spilling off the front tire, the air sliding around the wheels and frame, the way it reattaches and flows downstream into the rider's legs and arms. The result isn't just lower drag in a wind tunnel chart. It's a bike that, once it's up to speed, feels like it's leaning into the wind rather than fighting it, like a sail finding the exact angle where it stops slowing you down and starts pulling you forward.
Get the ONE up past 20mph and you can feel that shift happen. It doesn't ask you for more effort to keep accelerating. It asks for less.
What Goes Up, Must Come Down
Let's not pretend the ONE is a climber's bike. Our size 56 test build, SRAM Force XPLR with ENVE SES 6.7 wheels, weighed in at 18.5lbs, and it carries that weight in places a true mountain goat wouldn't. You feel it the moment the road tips upward and the pace slows. Below maybe 12mph the handling gets a little vague too, like the bike loses interest the second it can't go fast. Switchbacks at hairpin speed and out-of-the-saddle grinding aren't where this frame is happiest. If your rides are mostly vertical, there are better tools for the job.
But climbing is only half the equation, and the ONE seems to know it. Point it back downhill and the whole personality of the bike changes. The same long wheelbase and lower bottom bracket that feel like dead weight at 8mph transform into total composure at 40mph. The front end stays locked in through fast sweepers, the bike tracks exactly where you put it, and there's none of the twitchy, second-guessing feeling that aggressive aero bikes can have at high lean angles. It's not going to out-corner a Pinarello Dogma F. The Dogma still has the edge in pure, telepathic poise through tight technical descents. But the ONE isn't trying to be that bike, and it doesn't need to be. It holds its own, and it does it with a confidence that makes you want to push.
I found that out firsthand on Geiger Grade outside Reno, a steady, sweeping descent that drops over 2,000 feet in seven-plus miles of wide-open curves. With a tailwind helping push things along, the ONE picked up speed the way Factor clearly designed it to, fast, stable, and utterly unbothered, and I came off the bottom with a new PR. Some of that was the wind. Most of it was a bike that, once it's pointed downhill and let off the leash, just wants to go.
Why We Built With 1x
The ONE is built around one idea: less stuff slowing you down. The drivetrain follows that same logic, which is why we built our test bike as a 1x.
We spec'd ours with a 54T aero chainring paired with SRAM's 10-46 XPLR cassette, giving the drivetrain simplicity without compromising either end of the gear range. The low end is there when Geiger Grade bites back, and the top end holds up fine on the descent, so there's no real-world tradeoff.
Aero is where it really pays off. A front derailleur and second ring are real frontal area and drag, right in a zone Factor already spent enormous effort optimizing. Pull the front derailleur and you clean up airflow through the legs and drivetrain, no frame changes required, just real watts saved.
It's a small decision that fits a bike built to do one thing extremely well. 1x just keeps that focus intact.
Who’s It For?
Strip away the launch-book mythology and the white paper jargon, and the ONE answers a pretty simple question: who actually wants this bike? The answer is simpler than Factor's 40-slide geometry deck might suggest. It's for people who want to go fast, because fast is fun.
That's not nothing, and it's not everything either. The ONE isn't the bike for someone chasing the lightest possible build up a mountain pass, or someone who wants a do-everything frame that's equally happy on a century ride, a gravel detour, and a Sunday coffee shop loop. It's not particularly forgiving at low speed, it's not the bike you reach for when the day's plan is ten thousand feet of climbing, and it doesn't pretend otherwise. This is a bike with a narrow, deliberate purpose, and it makes you feel that purpose every time you get on it.
But if your version of a good ride involves a long straightaway, a tailwind, and the itch to see how fast you can actually go, the ONE delivers something most bikes can't: a frame that gets more composed the harder you push it, not less. The aero gains aren't theoretical, you feel them the moment you cross 20mph and the bike starts wanting to go faster on its own. The geometry doesn't just tolerate an aggressive position, it rewards it. And the descending character means all that speed comes with real confidence behind it, not just bravado.
This is a race bike in the purest sense, built for people who get a genuine thrill out of speed for its own sake. Club racers chasing every aero watt, weekend warriors who measure good days in PRs and not just miles, anyone who's ever hit a descent at full tilt and felt that grin show up uninvited. If that's you, the ONE isn't just fast. It's fun in a way that's hard to manufacture, and even harder to fake.
If the ONE seems like it’s right up your alley, we’ll see you at the shop.
