Shimano Dura Ace 7700 to Dura Ace 7900 upgrade
I have a 2001 Litespeed Classic equipped with a full Dura Ace 7700 group. Someone has offered to sell to me, for a very good price, a full set of Dura Ace 7900 components, brake lever shifters, front and rear brakeset, front and read derailleurs and a 10 sp. casette.
My questions is this, IF I upgrade with the components listed above, do I also have to update the crankset and chain rings (I currently run 53-39 with 170 crank arms).
My friend does not have the DA 7900 crankset/chainring and I kinda prefer the look of the 7700 crankset over the 7900.
So, can I upgrade all the other components and keep the old crankset?
Thanks for any help/suggestions.
BTW, today I saw the last stage of the ToC. I was at the top of the Norwegian Grade (in Thousand Oaks). It was pretty exciting seeing these guy ride up the same hills that I ride on weekends, albeait at a far faster pace.
