Bikerumor Pic Of The Day: Prototype SRAM Electronic Rear Derailleur?
Photo submitted by Matt Witkowski, “I took this photo several months ago. The owner of the bicycle requested anonymity, however simultaneously claimed to be an industry insider. The drivetrain was quite startling–it looked completely alien, and had no similarities to anything I had ever seen before. Amazingly, it appears as if SRAM has developed cross-compatibility with Di2: the bike was equipped with 7970 shifters! Unbelievable! Looks like SRAM really stepped up their electronic drivetrain R&D.”
