Shimano 105 gets electronic Di2 shifting technology

Continuing with the upgrade, Shimano is also launching two carbon road wheels, the C32 for climbing and the C46 for all-round use. Both share DNA with the C36 and C50 DURA-ACE and ULTEGRA wheels, balancing aerodynamics, lightness and stiffness. The C32 has a rim height of 32mm, an internal rim width of 21mm and a weight of 1,504 grams. The C46 is 46mm high, has a 21mm internal rim width and weighs 1,612 grams. Needless to say, both wheels are 11- and 12-speed compatible and tubeless-ready.
