If it were you.....would you get new Ultegra SL 6600 brifters or year old D/A 7800 / 7801 brifters? I keep going round and round on this decision. They are for the beater bike but it would be nice to have a rolling parts bike in case something on the good bike breaks. On the other hand since they are not serviceable age is a concern....
Please no "Should have gotten Campy" comments.
