¹ Size recommendations generally represent a rough guideline for quickly narrowing down the sizes from which to choose based on the body height. Bike fitting is a complex topic and other measurements and factors have to be accounted for as well. Since no two human bodys are exactly the same it is not possible to give a 100% correct advice for everyone. The best way to work out the correct size is to consult your Bombtrack dealer (info@bikejamming.it) or a professional bike fitter and have them determine the needed size.
