Sorry, I am a MTB buying rookie, long story short, I get a good discount thru Diamondback from my employer, and had ordered an Axis Sport for $430 to my door. This mostly for around town riding and maybe some light trails, but I just did not want a road bike-I don't ride like that (so you get a background).

However, when the box arrived, it says Redline on the side-they shipped me a Redline D610 instead. Looking things up, that actually seems to be an upgrade from the Axis Sport, so I guess keep it and don't complain?

Main difference is one is 27.5" and one is 29"--unless there is something else I am missing, please let me know! The frame size is the same so it should fit me just as well.

Thanks in advance!
