SRAM is now offering its Red eTap wireless electronic groupset with a new WiFLi rear derailleur that’s compatible with wide-ranging cassettes that feature a 30-tooth or even a 32-tooth sprocket.
When SRAM launched Red eTap a year ago, it was compatible with cassettes with a maximum sprocket size of 28-tooth.
The advantage of the WiFLi option – WiFLi is short for ‘wider, faster, lighter’ – is obviously that you can run lower gears to take the pain out of tough climbs.
The new derailleur is designed to work with SRAM PowerGlide and PowerdomeX cassettes, and the minimum cassette size that you can use is 11-26T.
The SRAM Red eTap WiFLi rear derailleur, compatible with existing SRAM Red eTap Shift-Brake Controls, is said to weigh 243g with the battery attached. That’s compares with 239g for the short cage version.
It will retail at £485 when it becomes available in December.
If you already have SRAM Red eTap and want to switch over to a WiFLi system, the kit you need (SRAM Red eTap WiFLi rear derailleur and battery, SRAM XG-1190 11-32 cassette, SRAM Red 22 chain) will be £745.
SRAM already offers WiFLi options for all of its other road groupsets so the introduction of this new Red eTap rear derailleur was wholly expected.

SRAM announced the introduction of hydraulic disc brakes to the Red eTap groupset six weeks ago, so it’s now possible to fit a bike with wireless electronic shifting, an 11-32-tooth cassette, and hydro braking.

I'm just about to climb on my trusty steed to go home and that has a 32T cassette on it and it works perfectly with Ultegra Di2.
The only thing that complains about it are my legs, but less than they used to...
For Danger Dicko; long Ultegra Di2 supports 32T
Aye, IIRC a number of teams in the pro peloton were using the Ultegra Di2 rear mech with the Dura Ace groupset to support the larger cassettes where needed.
Only 11-speed Di2 I think? 6770 was limited to 11-28T
This is great.
My Ultegra Di2 is limited by only being able to go up to 28t on my cassette.
Could try one of these http://www.bikeradar.com/road/news/article/expand-your-road-bikes-gearin...
The sooner this arrives at Rival level the better, so simple to install it will open the floodgates on mass-market electronic shifting.
