DB has been trying to re-enter the road bike market and has been offering some great bikes for the $$.
If you can get a DB Pod 3 for $500.....$200 more than the trek. I d go with that. It is a far better bike package than the trek. 105s vs 2300 alone is worth the difference. Add in a Carbon fork and BB30 bottom bracket, IMO no brainer. I would upgrade the wheels and brakes and you'll have a worthy road bike. In the future, If you wanted to upgrade the frame, 105s are worth transferring to another frame.
Don't buy anything, until you know your size!!
