i think there a sick idea i would happily £30 for one not £15, not everybody can just replace a frame when it gets dented to shit and cracks everyone i ride with saves up for months to get our new frames then after that we have them for a long time we, cant just afford to bash them up so sometimes we are hesitant to try certain gaps just incase we f**k the frame but if we had one of these we would all be much more confident and as a result our riding would improve
plus theres talks going on that you might be able to get them in colours and customized logos i think they would look pretty good
