Good day ladies!

I am looking into a cyclocross. It would be my secondary bike. So I did not want to pay more than necessary. If I could find a used one, it would still be ok. But not an old model.

Husband has been digging the web for what could be good for me (he's looking for one for him too).

So far, the only one I like for looks (I just cannot go dark again - My Amira SL4 is enough) is this one

It will only be used while on vacation, and sometimes to do some gravel bike paths around.

I'm just not sure about the derailleur as it is in Tiagra. Was always told it was not the best thing. I'm used now to Ultegra

Front Derailleur - Shimano Tiagra
Rear Derailleur - Shimano R350

Anyone has experienced with a similar bike. Altough it seems new for 2015?

Can we change it for at least at Shimano 105?

Thank you.
