What group are you putting on your Scattante that only has 8 speeds?
I believe Shimano 2300 is the only new 8 speed road group that you can buy right now...
I am putting my old Sora shifters from 04 trek until I get funds.I know lot of you really hate Sora but I bike 85% on the hoods so that's not an issue.Upgraded FD and RD to new 2011 105
already.
Even on 8 speed I rarely use the highest 2 rings.Basically only useable gears I use is 6.
