I am the current owner of this bike. I bought from speedmill on ebay. I love the bike but have had a serious problem with it. I'm hoping some one may have some helpful suggestions. The chainstay is so narow that the widest tire size I can use is 2.1 and if the rim gets bent even the slghtes little bit it rubs. Like I said I love the bike just having clearance issues with the rear rim. I was thin kin of throwing on Atomlab Pimp rims but don't think they will work with the small tire size of 2.1. Any suggestions or do you think the Pimp rims willl work with the 2.1 tire size. I love the bike but am frustrated with finding a new rimset that will work with it. the ones it came with bent real easy though I understand they were made to be light not strong. I weigh right at 200 pounds and bent it doing 180 bunny hops.
