I am building up a new bike. I have already bought the new 07 XTR rear der., rapid rise. Now I am having second thoughts about going with the DCL levers. Will the new rapid fire shifters work good with a low normal rear der.? I am not sure if I want to run the XTR brakes or something else, seems like if I go with the DCL I have to use the XTR brakes with them.
