seeing as I am on a friends computer and dont have msn I cant ask my smart msn buddies this question, so I'll put it to the masses (and risk embarasment ) I have a White Industries ENO trials freewheel on my bike. I fancy trying a 16 or 17 tooth cog on the front though to get a preffered gear (and a tad more clearence). I have seen you can get ENO freewheels with two cogs, either 16-18 or 17-19. my question is this....... Would those standard ENO freewheels outers be compatable with a trials one (my understanding is they are the same minus some strengening). If it does fit, my plan is to pop the the two cog outer shell on a lathe and turn down the bigger cog into a stump, I feel having the extra ring of the other cog should strengthen the outer shell quite a lot. Any thoughts? Obviously I want to be sure it would work before I spend my cash on it. badgers Al
