Two of Factor's finest race bikes, one bike fitter, several months in the saddle. Barry breaks down the ONE versus the OSTRO VAM across ride quality, stiffness, aero, weight, and more — and explains why he wants Factor to build a bike that splits the difference.
Know who has the best job in the bike industry? It's not Tadej Pogacar. It's not Mike Sinyard. It's not even Marianne Vos. Maybe someone behind the scenes? Like Josh Poertner of Silca, or Sebastian Weber at INSCYD? Nope and nope. It's me. I have the best job in the bike industry. Hands down. I don't think anyone else is even close. Why? Well, there are many reasons.
First, I get to focus on one thing and one person at a time. Thanks to the cycling community’s support, I am always busy. There is never a time when my schedule isn’t booked out at least two weeks in advance. During peak season, it reaches four weeks, but even then, I am only ever working with one person at a time, so my “busy” isn’t really all that busy. I get to focus on one rider at a time, and never have to deal with being pulled in three directions at once like everyone else in the shop.
And I only ever deal with people who want to be in the room. Everyone who enters the Regroup FIT studio wants to be there. No one is ever upset, angry, or disappointed. Not so with most other jobs. Imagine being a car mechanic, or an AC repairman, or a dentist… People HAVE to see you, often at very inconvenient times, and are generally not super happy about it. Not so in the bike fit studio! You only end up in my studio if you WANT to be there.
Another reason — I get to play with some very cool toys and very cool people. The Regroup team built an incredible studio, filled it with cameras, lasers, pressure systems, custom bespoke software, comfy chairs, coffee, and on and on and on. All that cool stuff attracts cool people who love riding bikes. Some are professionals, some are amateurs, all are passionate and engaged.
Anyway, I’ve dragged this out too long already. I need to get to the headline and the reason why you are reading this article. Let’s just say that reason number 4 why I have the best job in the industry is because I get to ride some very cool bikes.
People are always curious about what the bike fitter is riding. They want to pore over my bikes and check out the details, and more often than not, they ask themselves whether they should try out whichever bike I happen to be on. It is a great way to showcase a product, and for the shop to get behind a given model or brand. I usually ride the bike for a few months, then we sell it at a small discount when the next shiny bike comes along. My last two bikes have been very special indeed.
I was lucky enough to be one of the very first amateur riders to get to ride the all-new Factor ONE. (You can read my complete review here.) The ONE is an absolutely amazing bike. We had a client who was moving out of the country and who desperately wanted one. They were backordered at the time, but his fit was very similar to mine, so we sold him my beloved ONE.
But don’t cry for me Argentina. We replaced it with an equally badass Factor OSTRO VAM.
Since my first ride on the VAM, people have been asking me how it compares to the ONE. Honestly, it is hard to compare the two. While both bikes are perfect examples of what a modern race bike should be, they are still very, very different creatures. Outside the obvious cosmetic differences, the bikes also have very different geometries and personalities.
The ONE has a very unique voice. It gives the rider an inside look at where race bikes are heading, in a clear, straightforward way. It is simply stiffer, more aerodynamic, and sharper handling than any other bike I have ever ridden.
The VAM is the pinnacle of a more traditional line of thinking. It does absolutely everything well, and absolutely nothing poorly. It is light enough to be built at the UCI minimum, but also aero enough to leave most other “race” bikes in its wake.
Comparing bicycles is like comparing whiskey. Not everyone likes the same flavors, so we group them into categories. Peat, smoke, earth, wood, floral, fruit. We tell each other that one whiskey has more of some of those flavors than another, and the people who like things more earthy buy one type of whiskey, and people who like the floral flavors buy another. We do the same thing with bicycles, only instead of wood and fruit, we talk about stiffness, ride quality, weight, acceleration, and cornering. Below are some of the flavors that struck me about both the VAM and the ONE, and where I think they shine. Keep in mind that these are my taste buds, and not yours.
So here you go. Let the ONE vs VAM taste test begin.
This one is easy. The VAM is one of the smoothest riding performance bikes I have ridden. The reality is that all modern race bikes benefit from the amazing advances in tires and wheels. Disc brakes have allowed the industry to “recreate the wheel” in the very best possible way. Running 30mm tires at 50–55psi is absolutely sublime, and can make even the harshest, most unforgiving frame tolerable. With the VAM, those wheels and tires make an already smooth frame ride like a luxury car. With the ONE? Unless you live somewhere with perfectly smooth, flawless roads, running tubeless tires at low pressure is an absolute necessity. The ONE would quite simply rattle the brain right out of your skull. The aero tube shapes are amazing at slicing through the air, but, like a TT bike, not so great at absorbing road vibration.
WINNER: VAM
This is another easy one… The ONE is far and away the stiffest road bike I have ever ridden. Literally nothing else is close. When you push down on the pedals, the bike moves forward. It isn’t that the VAM isn’t stiff. It absolutely is, but the ONE is on an entirely different level.
WINNER: ONE
My unofficial testing (meaning riding a bunch of different bikes in fast group rides) puts the VAM up there with the fastest all-arounders in the peloton. It feels faster than a Madone, and on par with the Tarmac, but comparing an all-arounder with the ONE is like comparing a Jeep to a fighter jet. They simply aren’t in the same category. The ONE feels like cheating… especially over 25mph. If you are on a ONE, and the group is moving, you simply are not working as hard as the rider next to you.
WINNER: ONE
Similar to the aerodynamics category above, this one isn’t a fair comparison. The larger tube shapes of the ONE simply have more mass. That means that while the ONE takes more energy to get up to speed, once it is there, it is easier to stay there. The SRAM Force-equipped VAM I am on now is lighter in weight than the SRAM Red-equipped ONE I was on a month ago.
WINNER: VAM
Well… it depends on the acceleration. Accelerating away from a stoplight or out of a steep hairpin? The VAM wins every time. It weighs less, and it takes less energy to get that weight moving. If, however, we are talking about accelerating while already at speed, it is a different story. The ONE moves from 25 to 30mph effortlessly. 30 to 35mph feels the same. Get the ONE over 40mph, and there isn’t another bike on the planet that accelerates easier.
WINNER: It’s a tie.
This one is a little more complicated. The VAM corners the way all other well-designed modern race bikes do. If you get a 110 or longer stem on it, the VAM will never surprise you. It does exactly what you tell it to do, and responds to the exact amount of input you give it. The ONE changes cornering calculations significantly. The lower bottom bracket height is a genuine game-changer. If you know how to corner, you can lean the ONE over further, and with more confidence than anything else currently available. The progressive, modern geometry simply feels right.
WINNER: ONE
This is another “it depends” item. The VAM and the ONE are different tools for different jobs. If you live in an area without big climbs and you like to ride fast, the ONE is almost impossible to argue with. I literally giggled out loud sometimes while cornering the ONE at speed. If, however, you love to climb, and you routinely spend time spinning up climbs that last 30 minutes or longer, the VAM makes way more sense. It’ll still be a complete ripper on fast group rides, but you’ll smile a lot more than you will on the ONE during long climbs.
WINNER: It’s a tie.
Once again… It depends. As the saying goes, different strokes for different folks. I recently posted a reel featuring the ONE on Instagram, and the comments… oh my the comments (take my advice and always avoid the comments). The aesthetics of the ONE are polarizing to say the least. I personally think it looks amazing. It made my heart flutter a bit whenever I walked by it, and I was sorry to see it go. It made me want to ride more. The romance with the VAM is different. Maybe a little less passion, and a little more peace. Riding the ONE makes you want to ride fast all the time. The VAM is just as much a joy logging zone 2 miles as it is sprinting up the last hill of a Saturday coffee ride. Which bike will you fall in love with? That will depend on you as much as it does the bike… And who am I to tell someone who they should fall in love with?!?!
WINNER: It’s another tie.
I want it all. I desperately want Factor to build a bike closer in weight to the VAM, but with the aero edge and geometry of a ONE. It would instantly become the standard by which all other race bikes are judged. Based on photos of the currently unreleased new gravel race bike that Factor athlete Romain Bardet rode at Unbound 2026, I think they are probably thinking along the same lines. Fingers crossed!
