The AR15 is Felt’s first aero road bike with an aluminum frame made from their Superlight Custom Butted 7005 aluminum and is paired with an Aero Road UHC Performance carbon fiber fork and seat-post for wind-cheating performance. The bike is built up with Shimano 105 shifters and derailleurs for reliable performance. The 2014 AR series has been completely redesigned and the aluminium AR15 shares the same focus on aerodynamics as its carbon stable mates but brings this important aspect of power saving to a more affordable level.
The AR Road bike has drag numbers previously only seen on TT and Triathlon bikes and this is born out in neutral wind tunnel testing against not only his own framesets but those of the competition.The Felt AR15 is 14% more aerodynamic than its predecessor and between 28.7 and 31.1% faster than a standard round tube giving quantifiable power savings and time gains unmatched in the field. This system means that the frame around the post no longer needs to be overbuilt with relatively weak, compliant fibres and this allows for a lighter and stiffer junction at the rear end. Combined with this is an ultra-compliant seat post. As it no longer has to be strengthened to withstand clamping forces it is constructed of just 6 layers of carbon making it far lighter and much more compliant. The symmetric, ovalised shape with off-set top clamp, allows the post to be used in standard road configuration or rotated 180 degrees for use in Triathlon or TT events, positioning the rider further over the bottom bracket. With the AR15 you do not have to sacrifice weight, stiffness or ride quality to gain an aerodynamic advantage.
Shimano Ultegra / 105 11 speed groupset
Light action Vivid Shifting is just one of many features taken from Shimano’s top end groupsets.The 105 shifters and derailleurs incorporate Shimano’s Vivid Shift technology, with a light but positive feel all the way through the 11 speed Ultegra drivetrain, giving you the gear you want, when you want it, with the minimum of effort.The 4 arm chainset is lighter but still stiffer than most 5 arm designs. The four offset arms provide stiffness where it is needed most in the pedal stroke, ensuring all the effort you are putting in with your legs goes straight to the rear wheel.The symmetrical dual pivot brakes provide excellent power with minimal effort reducing fatigue in your hands and arms, especially on long rides.
Omega / Shimano RS400 Wheelset
Hand-built in France, Omega Aero Road rims and laced them to a pair of their RS400 Shimano hubs, with sealed bearings throughout, to provide a fast but durable road wheelset. These are wrapped in Schwalbe Marathon, high punchure resistance, all condition tyres, low rolling resistance on the straights and excellent grip in the corners.
Felt/Prologo Finishing kit
The Felt Aero Road handlebar is light but stiff and with its aero profile, it perfectly compliments the advanced aero framset.The Felt aero seatpost with it’s split design helps reduce vibrations from the road. It also features 3T DiffLock™ Comfort Module internals.The finishing touch is a Prologo Zero II Ti2.0 saddle. The perfect perch for hours in the saddle.
