Looking to update the groupset on my scott:
Here is what I have:
shift levers: ergopower 10sd record QS 2009
f/mech: centaur 2009
r/mech: centaur carbon 2009
calipers: chorus non skeletal polished
cassette: centaur 12/25 and 11/25 2009
chain: dura ace 2009
cransket: ultegra SL compact 2009
Have been looking at Athena 11 (although I dont wanna go to 11 as I have 10v shimano 7800/7900 mix on Cannondale six13) and I don't wanna go through all the hassle of what I used to go through when I had 9v on one bike and 10v on the other. I am all in favour of more sprockets the better as I lived in north east Spain where we are within 1-2hrs of the pyrenees and the Catalan foothills etc etc. It owuld be wonderful to run a 52-39 (or even a 52-38) on an 11-27 or eve n a 12-28. Here are total weights for the following groups: Athena 11: 2234g, Chorus 2144g, Record 2020. Would also be wlling to consider getting hold of 7800 and using 6700 levers as they are fully backward compatible. (I just hate the exposed cables; something that bugged me in 1988 and which 7800 users have never understood.) I may even swap out my addict r4 2008 frame, in white, and get hold of ad addict SL from 2008. I am currently selling a new HED JET 60mm 2009 rear wheel and will look at reynolds attack OR assault or possibly 2009 R SYS standard. All that MUST build into a 6,5kg bike and for all under €3000. The R4 is great but that extended seatpost makes it a ***** for travelling on planes.The R4 with the integrated seatpost is considerably heavier than the standard R4, however it does have a stiffer ride.So what group do I go for.....do I not complicate and opt for 7800 with ultegra levers? What does the 7800 group weigh?? Or do I go for campy 11 and complicated my life but have much improved hand positions like DA 7900 and DA 7800?? Has anyone tried campy 11 athena, chorus and record???
