Please note, while you may fit snuggly (according to the size guide) into one particular size, we advise you size DOWN for more manoeuvrability in tight corners or playfulness in flicking the bike in the air. Conversely, size UP for more stability through rough fast rock gardens, aggressive root sections, etc. Our staff will happily engage you in this wider sizing conversation to have you riding the right size bike for your height and riding style.
With decades of experience offering quality bikes and service, you can rest assured we have deeply considered the quality of the products we sell and have the technical skills to assist you.
We genuinely want our riders to love their cycling and to achieve this we focus on ensuring our riders purchase the bike they truly need and want and fits their riding purpose.
We also genuinely want to look after our riders post purchase - its a duty of care that we take seriously.
Lastly, we are riders ourselves. We are in this business because we are genuinely passionate about riding all types of bikes and are here to share our knowledge to help enhance your riding experience.
