So I see some Dura-Ace 7900 features have reached Ultegra:
- Hollow outer chainring and hidden chainring bolts
- Shift cables now run beneath the handlebar tape. Brake-lever blades are composite. Lactic Acid Threshold claims these shifters will maintain B-level interoperability with 6600 equipment, unlike Dura-Ace's requirement that you use a 7900 front derailleur with the 7900 front shifter due to its altered actuation pattern. For this reason, I'm not sure if the 6700 front shifting will have the short stroke of 7900.
- Brake calipers now feature the low-profile adjuster barrel and some slight lightening of the forgings (note the flutes in the caliper arms by the brake-pad slots)
- The chain now features a master link and weight-relief slots on the inboard outer plates and the outboard inner plates, like Dura-Ace 7900
- The revised short-cage rear derailleur is now officially cleared for use with 28-tooth cassettes, and there will be 10-speed cassettes available in the 11-28 combo hitherto only available in the ridiculously-expensive Dura-Ace 7900 series.
- Shimano adds an Ultegra-level tubeless-compatible wheelset
- According to the cyclingnews.com article, the double-chainring setup will be available in July.
