replacing Campy8 with Shi.10- can mix?
Got a new/old bike, Record 8-sp. Want to upgrade to 10-sp for higher and lower gear, and already have Ultegra shifters and 11-28 sram cassette on Neuvation wheels. Shi. site says only DA can handle 28t rear. Do I need the DA or will a 105 or Ult work, could I use a Force rear with Ultegra shifters? Will I have to change Record front der.? Rebuilding is tough!
