    Looks nice but falls apart

    Bike rides nice and feels good but will fall apart on you after a few months, do not ride on anything other than completely smooth pavement or it will shake it brakes and derailleur loose

    Great beginners platform

    Is not "plug and play fender" compatible but DOES have standard fender and rack mounts. This does NOT have the plug and play holes w/ set screw on higher level Specialized bikes. Terrible micro-shift components. Otherwise good starter bike.

    Lovely bike and easy to set up. However, I had to pop into a local cycling shop and ask them to modify the gears on my first ride as they kept slipping. Now it’s lovely and smooth
