The frame of the AR4 Ultegra is from the AR (Aero Road) series of Felt Road bikes which means while lightweight, rigidity and comfort are still important factors the primary concern of the design is aerodynamics. This means every effort has been taken to smooth the path of wind over the frame including a shaped downtube, bladed fork, moulded seat-tube (to shield the rear wheel) and an aero shaped seatpost too.

Even the internal cabling has been thought through with the entry point for these being behind the stem on the top tube (a design feature borrowed from Felt's DA Time-Trial/Triathlon bikes) where the air is already 'dirty' as it passes around the steerer. You get twin bottle cage mounts, a replaceable forged aluminium rear derailleur hanger and Felt even chose to keep the AR frame un-tapered at the headtube to reduce the overall frontal area presented to the wind. No excuses then!

Shimano Ultegra 10 speed components adorn the AR4 giving you impressive performance at this price. This includes the integrated brake and gear shifters, brake calipers and both front and rear derailleurs. The chainset is a compact FSA team issue model made from carbon fibre meaning it is both light and stiff as well as providing the spinning benefits of a 52-36 chainring set-up too.

For the wheels you'll find Shimano's R530 wheelset hard to beat in terms of reliability and their 30mm rim profile keeps things aero too. There are more aero wheels on the market which have correspondingly eye-watering price tags but the RS30's are not just about being aero and can handle their fair share of climbing and sprinting too.

For the finishing kit Felt supply their own-brand cockpit and aero seatpost but you get colour matched tyres from Vittoria which is a nice touch.

Whether you're a club rider looking to shave seconds off your times or a triathlete looking for one bike solution the Felt AR4 makes plenty of sense.
