SRAM adds WiFLi tech to Red eTap groupset

While SRAM’s wireless Red eTap groupset has been around for a year now, it hasn’t been possible to fit a wide-range cassette for spinning up really tough climbs. That’s now changed with the addition of SRAM’s ‘WiFLi’ technology, which provides a longer-arm rear derailleur and lets you fit 11-30t or 11-32t cassettes.

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.

WiFLi rear derailleur

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 / US$610 / €570 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 / US$920 / €907.
