We’ve been sitting on this info since March 1st when we originally posted about Shimano’s new cyclocross components, but now that Shimano has finally lifted the embargo date on the info, we can give you the real scoop on the new Di2 electronic shifting for Ultegra.

Ultegra will receive two updates for the 2012 model year. The first update is cosmetic with the addition of a Glossy Grey color. The second is the integration of Di2 electronic shifting for Ultegra. Since the introduction of Di2 at the Dura-Ace level, many improvements have been made in the wiring harnesses. The original four wire system has been replaced by a more simple two wire system that allows cable diameters to be reduced by 3mm for lighter weight and a more slim profile. Cable selection has also been simplified with all connectors being identical so that cable inventory becomes easier to manage. Further refinements include more ergonomic shifter/brake lever hoods and brackets due to the electronic integration and a simplified junction box that lends itself to discreet external or hidden internal cable routing. Retail price target places Ultegra Di2 below the MSRP of Dura-Ace mechanical.

Already released updates to Shimano products include:

  • FC-CX50 and FC-CX70: The new CX cranks will have 46-36T gearing and Hollowtech II construction for maximum power transfer
  • FD-CX70: The new front derailleur is designed specifically for used\ with the new crank gear ratios as well as optimized for the harsh conditions associated with CX racing.
  • BR-CX50 and BR-CX70: The new cantilever brakes have better clearance compared to the BR-M550 and the performance of Super SLR. The BR-CX70 has the additional benefit of using cartridge road brake pads for easy pad replacement.
  • CX50 components will be available November 2011 and CX70 available August 2011
