Price comparisons should also have the components and features offered taken into account. Check what groupsets and wheelsets are included and if there are extras such as integrated handlebars or other aerodynamic enhancements for the bicycle. For example, the Endurace might have a better groupset which would be an advantage at the price mark, but then an aluminum wheelset is rather heavy, the Aeroad might bear a lighter aero carbon wheelset but rather a heavier one, and the Ultimate could boast a fully integrated adjustable aero handlebar. Make your choice whether you will prefer electronic groupsets and low weight aerodynamics only or some compromise on these preferences will be required.
