New SRAM X.X what do you think?

Tweet

The new SRAM X.X is out and features a new 2 X 10 design, I don't think there is much question that on the racing side of things going to a double up front has been in the works for a while, but every time we add another cog to the rear cassette we have to have the durability debate. So here it is, do you predict massive amounts of really expensive chains breaking this year, or will this move be like so many others where everyone is up in arms about the narrower chains, but at the end of the day no one notices a durability issue?
