I have been absolutely thrilled with my SL4. I like everything about it - the geometry is great for me, fit is spot on, and bike is a joy to ride. It's an amazing combination of ride qualititles - it's stiff, light and responsive, while having stable handling, comfortable geometry and it does a nice job of dissipating road harshness without feeling the least bit mushy or disconnected.

I got mine at the BikeSource Ranch Mart location. They were great to work with, and give me a better deal than I would have expected on a brand new model. A very good experience all around. And with the current pricing on the upgrade kits, I can have a di2 bike in the matte black color scheme, and still be cheaper than the factory di2 model. And once I sell off the mechanical Ultegra parts, it will be a complete no -brainer.
