Shimano Ultegra Di2 12 Speed Upgrade Project: Hands-On Ride Review // Part III

What’s the Shimano 12spd Ultegra Di2 R8170 groupset really like as an upgrade from the previous generation Ultegra Di2? This video covers a number of key differences and my observations after a few months of use after upgrading my Giant TCR from R8070 to the new R8170. There’s a few little things that I only discovered about this groupset once I’d had it installed on the bike.
