i believe that cost is an issue and then its down simply to who u believe over the posts, i think supercycles has a very good point and a very goos scheme in replaces for half price(dually noted). everyone knows a mate who had broken the unbrakeable, i believe that there are a few other free wheels u could try, depending on your budget just look over the trials sites, like trials-uk tartybikes etc. if u are a novice or beginner like me then maybe a good quality cheaper free wheel is more up your street. to that end, the more u can spend mostly gets u a better freewheel take what you want from all the posts on hear but in the end you will buy one or the other and u will be happy with your product don't forget if u get it from supercycles they are very kool about things if u have a problem with the item.
