This might be a stupid question but I just got my new Iron Horse Maverick and I absolutely love it, my only complaint is that when I coast the chain goes slack. This made it kind of tough when I needed to pick up some speed quickly and my first few strokes don't provide any power they only tighten the chain. How can I keep my chain from going slack when I coast? Also, could this be related to the fact that the cranks spin if I take my feet of while coasting? Also a friend who has an Iron Horse Maverick 3.0 suggested taking a link out, as he had the same problem is that the right solution?
