This video contains product placement from Hunt Bike Wheels. Conventional wisdom says that aero wheels are faster on the flat and lightweight wheels are faster on the climbs but exactly how much faster? Senior technical writer Simon von Bromley delves into the lab to find out! Brands often produce their aero claims based on testing by professional riders, at speeds that are often unattainable to the “normal” rider. What exactly are the differences in the real world, for a normal rider like Simon? Does rotating weight actually matter on climbs? Are aero wheels actually worth it? Thanks to our sponsors, Hunt for helping to make this video happen by sending us the wheels featured. We have the Hunt 60 Limitless Aero Disc and the 32 Aerodynamicist UD Carbon Spoke Disc. The aero-optimised 60 Limitless wheels use a highly progressive, ultra-wide design, with a 60mm deep and 34mm wide rim. They weigh in at a claimed 1,669g, which are light but not ultra light. On the other hand, the 32 Aerodynamicist UD Carbon Spoke Disc wheels are designed to be as light as possible. They use a shallow, hookless carbon rim which measures 32mm deep and 25mm wide. They also have carbon fibre spokes, which are said to be both lighter and stiffer than conventional steel spokes. The aerodynamicist wheels weigh in at a claimed 1,213g. Do you feel the difference aero wheels make? Or are you a lightweight wheels no matter what rider? Let us know in the comments!
