Need to choose between Dura-Ace 7800 and Ultegra 6800
I am looking to upgrade my bike. It is a Scott CR1 with all 105-5600 components. It has over 2000 miles.
Things are a little clunky sometimes but generally work fine.
A friend is upgrading is Dura-Ace 7800 with about 3000 miles on it. Seems to be in good condition. He would sell the whole thing, brakes, crank, cassette, etc. for under $400
The other choice is to save up and buy a Ultegra 6800. I would get 11 speed cassette which is nice. It has good reviews and is newer technology so it should be supported longer. Also, replacement parts would be less expensive.
I am looking for ideas on how to make the decision.
