? about changing chainrings
I just ordered a Motobecan Fantom Cross Pro. It comes with a TruVativ GXP External Outboard crank with 48-38 chainrings. I would like to make it a compact 50-34. Can I just change the chainrings? It comes with a Shimano Ultegra 6600 front deraileur. Will I need to get a compact deraileur? I'm using this bike as my bad weather road bike more or less. Will use it on some rails to trails, and possibly a little bit of single track. I live in an extremely hilly area, and I have a compact on my road bike. I'd like to have the same gearing on this bike, but don't really want to buy an new compact crank unless I have to. Thanks for any advice....
