Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Felt AR Advanced Disc 105 Starry Night Aero Road Bike





The all-new AR is the bike you need if speed inspires and delights you. Whether you are in the hunt for PRs, segments, or Olympic gold, the AR is built to get you to your finish line. Not just faster but better in every way, the new AR is designed with performance in mind. We know that going fast isn't only about cheating the wind—though the AR doesn't disappoint on that front. It's also about keeping yourself fresher and more composed than the competition. This is why we built the new AR from scratch, starting with a blank slate. We took the performance data from the existing AR, knowing just how fast it is and that it remains a reference point for racers and much of the cycling industry. But, on top of this, we elevated the importance of ride quality and handling to ensure that the total package is simply the fastest and best aero road bike we've ever designed. The AR is a whopping 9% faster than the previous AR depending on the conditions!

WEIGHT DISCLAIMERThe most accurate way to determine a product's weight is to have your local dealer weigh it for you. Because we understand that weight is an important metric, we strive to list it when possible. When listed, weight is based on a single sample in a specific size and with all items as shown in the photo. It is not an exact indication of what your bike or frame will weigh, as there are tolerances in many variables involved (size, finish, hardware, components, and accessories). Felt continues to be an industry leader in weight and performance.SPECIFICATION DISCLAIMERSpecifications subject to change without notice.

Professional Opinion



The aero paradigm has evolved. Gone are the elongated, deep-section, teardrop shapes and hard edges that were previously thought to be the most efficient at slicing through the wind. The latest industry research and theories have shifted aero bike development towards truncated, squared-off profiles (sometimes referred to as "Kammtail" designs) that have been optimized for real-world riding conditions. As a result, thoughtfully designed bikes will perform better during the actual riding and racing conditions that cyclists encounter most often. As the performance benefits of this new paradigm have taken hold, we've seen a validation of the speed gains ourselves. Our development of the new AR followed these theoretical models and industry improvements with more deliberate, hands-on efforts to advance our own platform.


Disc brakes are found on the entire Felt road line-up. Our all-around road bike model (FR series), our cyclocross race bike (FX series), and even our flagship triathlon model (IA series)—all of which have won World Championships in recent seasons—feature disc brakes. Through testing and experience, we know that disc brakes can win races on the biggest stage. So from the beginning of the AR project we knew that the next-generation bike would have disc brakes exclusively.


While fully hidden cable routing systems can appear aesthetically minimal when installed in a precise configuration, a truly closed-off system carries with it several drawbacks. Chief among these is a significantly more tedious and time-consuming maintenance process. It also makes the bike more difficult to easily break down for travel. And, due to inherent space constraints, many fully hidden systems can cause excessive wear and tear on cables and housing if not perfectly set up by an expert mechanic. Likewise, one-piece handlebar-and-stem configurations limit a rider’s ability to dial-in their preferred body position, as well as fine-tune their favored steering interface. With the AR’s tried-and-true system, riders have the option of using our semi-integrated stem (in lengths from 80mm to 140mm) or their favorite stem in whatever material and length they prefer, as well as their preferred handlebar in a myriad of materials, shapes, and sizes.


We pioneered a unique seatpost design for the previous-generation AR, and it offered such a high level of aerodynamic efficiency and a superb ride quality that it only made sense that we would revisit it for the new AR. This latest version still features the signature split design that not only allows for an aerodynamically optimized interface between the post and the seat tube junction, but the two halves of the post flex and shear independently of one another, which increases overall rider comfort. We also created a co-molded rubber insert that lives within the junction of the seatpost and seat tube, giving the entire interface added compliance. Finally, the slotted seatpost design allows for the use of a proprietary clamping mechanism that results in a lighter overall setup thanks to the use of thinner carbon walls, and a more finely tuned level of compliance for rider comfort. So what does all this mean? The new AR’s seatpost provides 112% more flex than the seatpost of the previous- generation AR. Purists will say that an aero race bike shouldn’t be “comfortable.” But we disagree.
