ER:ONE - Aero/Racing

The ER:ONE road frame represents a step forward in structural engineering. To achieve the combined goals of low weight, high stiffness, and reduced aerodynamic drag, every stage of development demanded precision. Each carbon ply is strategically oriented, resin ratios are optimized for strength-to-weight efficiency, and tube profiles are refined through repeated simulation and testing. From layup design to functional stress analysis, every parameter is verified and re-evaluated, ensuring a frame that balances efficiency, durability, and speed under real-world racing conditions.

Bike was delivered with all necessary parts in excellent condition. It also came with parts that I didn't expect: 28mm continental gp 5000 S TR tires, wrapped handlebars, a computer mount, dura ace chain, sella italia saddle. Very happy with my purchase!

My ER:one arrived in perfect condition. I have several hundred miles on it and it’s a blast to ride.

So far so good! Rocket ship of a bicycle, feels faster then my Cannondale SuperSix Evo for sure. Thinking of purchasing the AR One now!

I ordered the ER:ONE in XXL with Dura-Ace Di2 components. The ordering process was straightforward. It's possible to customize the seatpost and handlebar width and stem length. It also appears you can choose between a 52/36 or 50/34 crankset and a 170mm or 172.5mm crank arm length. However, this is never actually requested. In my case, it defaulted to 50/34 with a 170mm crank arm length. This isn't the crankset I would have ordered. After all, the frame size is XXL, so I would have expected a 172.5mm crank arm length.

Delivery took approximately two weeks. I received regular updates on the delivery status.

The bike arrived in two separate packages. The first package contained the saddle, seatpost, wheels, tubes and tires (Continental GP 5000 TR), brake rotors, cassette, battery for the Di2 electronic shifting system, and a few small parts.

The second package contained the frameset, which was pre-assembled except for the fork steerer tube being cut short.

Regarding the packaging:
Both cardboard boxes were damaged. The wheel hubs lacked the usual plastic caps. Since the hubs had punctured the cardboard due to the lack of protection, they were (superficially) scratched. Nothing that affects usability, but it's annoying.

The frameset was very well wrapped inside the box, and sensitive components were additionally padded. Everything was complete, no damage.

Regarding the bike:
Fully equipped, it weighs 7400g. That's really good for the frame size. Perfect finish, highly precise workmanship. You can usually see how well a carbon frame is made by looking inside the tubes. There's absolutely nothing to complain about here.

I've ridden the first 1000km and I can say: Wow, this bike feels fast!! I usually ride a Scott Foil on the road and it doesn't feel any better than the QuickPro ER:ONE in any respect!

In search of my next crit race bike, I ended up going with the ER ONE from QuickPro. I was hesitant buying a bike that I could not sit on or ride. Reaching out to their support through chat, QP was very helpful in making sure I chose geometry that would be near perfect to my current fit. I can say now that I have received the bike and been able to ride it, it's absolutely everything I wanted. The fit is great, the stiffness and responsiveness is excellent. The value of bike build I got for the money is second to none. I'm a QuickPro fan!

PS: I had a small issue after delivery and customer support was responsive and went above and beyond to take care of it!

ER:ONE is the most sophisticated frameset period. The purchase process is simple, timely, and very competitive from a price point. I highly recommend purchasing a complete bike from Quick Pro USA. I even when with a custom paint job, and the bike showed up at my house ahead of estimate. Thank You to the Quick Pro Team.

This is a wonderful bike. The bike feels fast. If I had any negative comment would be that the front end feels a bit twitchy. Overall love the bike and would buy again.

Best bike I've had, light, stiff, fast, aero... highly recommend. Very good value, and better performance than most of the mainstream brands.

Mi sembra buona l'efficenza aerodinamica della bici, bella l'estetica , la forcella eccessivanente mastodontica esteticamente anche se sembra efficente. Non ho ancora un giudizio sul peso e sulla risposta in salita

I‘m very happy with the ER One especially considering the Price only minor negative details like the front bottle Mount being a bit too high so it‘s hard to fit big bottles
