Blending the lightweight, stiff and quick-handling performance of a professional-grade carbon fibre road racing bike with the aerodynamic advantages of a time trial bike, the AR has Redefined what a road bike is capable of accomplishing. Three years ago pro racers challenged Felt to put its aerodynamic expertise toward designing a new road bike. The racers asked Felt, makers of the world's fastest time trial and track bikes (the DA and the TK1), to help them improve their performance and efficiency in the road races they compete in day in and day out. The result of this design is clear. Against its true adversary-the wind-the AR gives racers a tangible advantage. Testing sessions at the San Diego Low Speed Wind Tunnel facility have proven that, depending on speed and wind conditions, a rider can reasonably expect to save from 58 to 75 seconds over the course of an hour when compared to a bike with round frame tubes in similar conditions. Like all Felt road bikes, the AR is characterized by crisp handling. The proprietary blend of carbon fibre materials used to construct the frame give it the stiffness and ride quality for which Felt is known. Beyond the frame, each AR is outfitted with a full complement of race-ready parts. From aerodynamic wheels to flawless drivetrains and gearing that's suited to racing speeds, the AR Series is designed and built to deliver you to your best performance ever.
Pros: Good value, Good quality, Comfortable, Lightweight, Looks great, fast
Cons: poor wheels
Went through a long period of weighing up options, AR4 against a number of other aero bikes including Scott Foil, I rode a few of them and other more standard bikes such as Madone and Domane and Bianchi.
The Felt got me on the way it looked really; stealthy in carbon finish which you have to see in the flesh to appreciate and the psedo TT bike look.
Does it work? I've found that on a flat road with a good surface I can maintain a higher speed with less effort than on my other bike; this benefit only really kicks in at 18mph, so if you are only using for leisurely riding it may not be a huge reason to buy.
It goes well up hills and is fairly stiff when apply more power. It is suprisingly comfortable to ride on longer routes, despitethe mostly poor road surface in N.Bucks.
I felt the shimano wheels didn't really compliment the bike in that they aren't really aero or that light, so I upgraded to Campag Bullet Ultra's.
