I'm finding that when jumping my mountain bike seems to be very nose heavy no matter how far back my saddle is. What effect will moving to a shorter stem length have?
My bike, a Boardman FS-PRO came with a 100mm Richey stem. I think that moving to a shorter stem length will allow me, and my short arms, to sit further back on the bike and hopefully make steep dropoffs a bit easier to ride. I've heard that shorter stems make the steering quicker too. Will this make my bike unrideable?
