S_DOG34, I have Ultegra 10 speed groups on two of my bikes and it performs beautifully. The cranks are especially smooth with the external bearings and are very stiff as well. The shifting is quiet and precise. You made a good choice, at a great price and it will serve you well for many miles to come.
