No, I haven't actually got another bike! But Joop's had a new Chorus 11-speed groupset fitted and I even convinced Warrick to service the hubs on those Eurus wheels and put on new tyres so it looks and feels like a new bike!
Between eating and sleeping during the week between Xmas and New Year, I managed to get out for a few 2-3 hour rides and am really pleased with the new Chorus.
I especially like the shape and texture of the new lever hoods. It wasn't something I noticed immediately on using them, but when I later rode a bike with the old-style levers I suddenly felt that the old shape was really uncomfortable!
Other noteworthy improvements are the shorter throw of the new shifting mechanism, and improved braking performance. The brake calipers themselves aren't any different, but the shape and action of the levers is more comfortable and requires less effort to pull. I don't think it'll be long before I replace the levers on one or two of my other bikes.
I also want to change these bars. I put those FSA Wing Pro Alloy compact bars on just to try them out when they first became available, and never really warmed to them. Now I find that the shape of the new Campag levers makes the shape of the compact bend look really odd. But I haven't decided what to replace them with. I'd really like to try the Deda Campione carbon bars, but don't think my budget will stretch that far (even at the staff discount price). I'll probably just end up putting the old Stella Azzurra Profi bars back on. Then my bars, stem and seatpost will all match again and that's a very important style consideration, you know!
