I have to go with the fit suggestion as well. With the use of the adjustable stem they can determine just what stem you need as well as where your saddle should be positioned. They can shim the cleat to help with foot position and even give you a different stance on your platform. Turns out my stem was too long and it was causing me to lock my elbows when on the hoods. The group ride tomorrow will be the proof of the pudding but the short ride after my fitting felt a lot better already.
