About Us


Working from our studio in the village of Lower Upham near to Winchester and Bishops Waltham, we provide professional bike fitting, performance testing and bespoke coaching plans, biomechanical assessments and sports massage.

Our studio is situated a short distance between Southampton and Portsmouth and just outside Winchester. We are 10 minutes off the M27 making us easily accessible for those travelling from further afield.

In either direction are beautiful cycling areas including Meon Valley, the South Downs and Test Valley.


Garth Kruger

As founder of Vankru Performance Cycling, having competed on the road and track for over twenty five years (including as a semi professional rider in Italy), Garth created Vankru Cycling with a desire to use his knowledge and experiences to help athletes excel and overcome the hurdles each and every one of us face.
