This is a NEW Shimano Di2 ROAD group. All electronic! Cool as can be! 172.5 cranks, 11-23 crank/english BB. Full group/accessories that are normal.(picture does not show chain or cassette but they are included). $3100 with Free shipping in the US!!! Enough said. Please, see Shimano.com or other sites before asking mundane questions about battery life, cables etc. I am just selling a group that I will not use as Sram Red is all I will ever need! In other words, I had the group on order, love the Red and out it goes…PayPal of course.
