    Please help me to decide between a 2012 Trek Cobia and 2012 Spcialized Carve Comp

    Hi guys I was hoping someone could help me to make a decision between these two bikes. I have been deliberating for some time over these two setups and still am not anywhere close to a decision. I love the color of the Trek Cobia ( red and white) but feel the frame is inferior to the specialized. I think the Specialized has a better frameset but inferior drivetrain ( SRAM v Alivio).

    I wonder if I should buy the specialized for $200 more and upgrade the drivetrain at a later date. Or should I save the $200 and upgrade something else on the Cobia?

    I have tried both at my LBS the Specialized lighter and had a better frame, the Cobia felt better to ride and had a better fork, but was heavy 30lbs. Cobia was cheaper too.

    My quest continues as I have not decided yet.

    I'd go with the one with the better ride.

    Those are tough choices for sure. I love the frame on the Specialized but give the Cobia a VERY slight edge on components.

    It has the better fork but everything else seems pretty much equal IMO.
