I highly recommend carbon if you can swing it. It just does everything better. I hit a bump yesterday I didn't see and one hand came off the bars but I saved it since most of the shock was absorbed by the bike. On a steel bike I would have crashed for sure.

I'm still not a fan of the electronic shifting although a lot of serious riders are using it and pretty much all the pros. A good friend fought his several times which left him stuck in one gear for a long ride.
