Whether considering a new bike purchase or getting the most out of an existing bike, just as important if not more so to price and spec, is a bike that fits. 

Our head bike fitter is Level 3 IBFI qualified, and has extensive experience fitting bikes of all sizes to riders of all needs.


Based in the North East, Triology caters for all types of riders, but the priority is always to make you as comfortable, efficient and in turn as fast as possible. We incorporate the World-renowned state of the art Retül 3D motion capture system, into our bike fit process, and can fine-tune your optimum position to within degrees, but our most important tool is experience, Andy has more than 3000 fits and over10 years of professional bike fitting behind him, and a considerable knowledge of Human Biomechanics and Physiology, ensuring you get the most from your current bike or future purchase.

If you are looking to purchase and unsure of the correct size and geometry of a potential bike, using our Sizing Session and custom fitting jig we are able to accurately measure you for the correct frame size of most available bike brands on the market, before making that prospective purchase. Saving you the risk of wasting money on a bike you have to live with but may never get the best out of.

We have a range of brands at our disposal for our bike fitting service, including Retul, Gebiomized, Bioracer, Formthotics and G8 insoles, aswell as contact point components from some of the leading saddle, stem and handlebar manufacturers.
