NOTE: As with any complete bike, J&R Bicycles recommends that you have a professional bicycle store build your bike. Bikes ordered through mail-order come partially assembled and need to be inspected and assembled by a bicycle mechanic. Failure to do so may void the manufacture's warranty. Manufacture's warranties differ for every brand. You can check the brand's website for warranty information.
