Ever since the Di2 was introduced, at prices that most mortals would need a mortgage re-fi to afford, there have been rumors flying (OK, make that wishes being aired) that the line-topping electronic groupset would beget a cheaper Ultegra version. Which would, undoubtedly, be a coup for the Japanese company, and confirm its leading position in terms of consumer products vis à vis its Italian rival.But, so it seems, the rumors have no basis in fact. Shimano Europe has released the following short-and-sharp press release: “On the Internet some information was published about Shimano Ultegra Di2. Please note that this is not official Shimano information.”Now. BikeBiz (the source of this info), is taking this denial as a sign that there may in fact be some substance: why should notoriously tight-lipped company need to deny anything… are some execs feeling a little jumpy, perhaps?Think you that the lady doth protest too much? (With apologies to Shakespeare.)UPDATE: We’ve heard rumor from an anonymous industry source that the current model will actually become the electronic Ultegra and that Di2 is the one getting some new-ness…smaller, lighter battery, perhaps?UPDATE #2: We just heard actual confirmation from an absolutely reliable industry source that it’s happening! Even better, it should be around half the price 0f Di2, which means it could very well put a hurt on the standard Dura-Ace mechanical group, especially at OEM…more as we get it!
