Never knew there were so many stems and bars to choose from. I'm hesitant to purchase anything higher quality as I don't want to "invest" money into the bike if I don't know if I will be happy with the end result. My understanding is that if I purchase a stem and/or handlebars and I install them the bike I cannot return the items. They would probably have marks or scratches and cannot be returned to the seller. That is understandable. Is that the experience of those on this forum? Once you install the parts you are stuck with them? I guess I could resell the items as used on Ebay if they don't work out.
