Trampa Boards Ltd are able to tune the flex of their decks relevant to the riders weight height and Ability. Please use this Flexometer as a guide to help you choose the right board for you. The information is to be interpreted as a guide only as there is no fixed rule as to which is the exact right deck for you. Depending on the weight, height & ability of the rider will help determine which is the right deck, but of course the most important factor is personal preference as to how the rider wants their deck to feel.... Some riders like it flexi, some like it firm, some like it very very stiff.... It depends on what you are doing on your board, i.e. freestyle, freeride, boarder-cross, altho there is guidance there is no right & no wrong just personal preference and when purchasing a deck from Trampa we want to make sure you get it exactly the way you want it!
