Taking care of the details for speed

SpeedTheory is based on David Bowden’s extensive knowledge of bike fitting, equipment, coaching and power analysis. With the mission to cover every detail to make you faster.

David has designed the Velogicfit 3D Motion and 3D Aero performance bike fitting products that he uses in the studio. He has trained bike fitters within NZ and around the world. 
With his work consulting to Profile Design he has been at the forefront of raising the standard of aerobar and road bar design.
Profile Design’s current lineup shows what happens when somebody who actually rides tri bikes understands the way tri bikes should fit, understands the imperatives of the product and is in charge of making the product.

Whether you are wanting to be more comfortable on your bike, be faster and more aero-dynamic, break your own records or a world record, if it is on a bike you need to talk to David. He can even help you before you purchase your bike to ensure it will fit you like a glove.
