Strengths: Shifting - The SRAM Dual Drive is like driving a car with an automatic transmission.
Weaknesses: The Brakes - I have flown over the handlebars twice. It's probably my fault for braking incorrectly.
I have ridden this bike 1150 miles and I love it. It is more comfortable than my mountain bike (a 10 year old Mongoose) and my roadie (a Cannondale R1000).
It is the easiest shifting bike I have ever been on.
The frame is meticulously welded together and the graphics and paint job are superb. The seat is comfortable and the tires (700X38) are still flat free, which is more than I can say for my roadie.
