Hi,

Firstly, please forgive my bicycle ignorance.

I am currently riding a Giant OCR 3 (2008) which has a Shimano 2200 Crankset on it. I am looking to upgrade to an Ultegra 6700 Groupset. The current front derailleur on the bike is a brased derailleur (which I assume means it has a bracket mount that screws to the bike). I'm just wondering if I get a brased Ultegra 6700 front derailleur and change the crankset if it will fit correctly. The new big chain ring will be exactly the same size as the old one.

I have read of people having trouble with such things in the past.

Has anyone had any experience with this? Any other problems (other than telling me to buy a better bike) that I might face if I upgrade the components?

Thanks.
