Thanks. I'm perfectly aware of what WiFli is, running WiFli Force setup myself. My question (not a joke) was based on all the complaints about "sleeping" I've seen said they had installed the WiFLi RD, leading me to wonder if maybe there was a firmware difference since WiFLi version was released about a year after the original short cage version.
scott s. . Battery life being super short is usually one of the first indicators. |
Off topic, but how many hours are you guys getting on your batteries? My bike stays in the car and I generally remove the batteries after rides. I assume they only wake up and discharge while connected. They are exposed to sub-freezing temps in the winter and 100+ while in the car in the summer. Anyway, I only get 35 hours of riding at best between charges. |

I got eTap WiFli just a week ago, and I'm glad to say no issue so far (crossing fingers :))
:beer: Geoff |
So I sent my RD back to the vendor I bought it from for a replacement from SRAM, and I received the replacement and installed it yesterday. Today I rode 60 miles without a problem. As far as I know the new RD has no upgrade/fix or whatever so I guess the problem could happen again. I’m keeping track of the miles I have on the new derailleur. |
How long until the SRAM fanboys accept the fact that ETap sucks?
You are paying SRAM to be test-riders. |

Anyway, I only get 35 hours of riding at best between charges. I've got 2,300 miles on mine with no issues at all. I don't dispute that there's issues out there, but I'd imagine its a bit of the squeaky wheel scenario. Maybe even a higher than normal rate of issues, but still a relatively low % compared to the total population of users. |

I suspected it would have some problems, so I tried to warn others to wait for the second version. Sorry if you didn't get the memo. |

35 hours seems like quite a bit to me. I haven't really measured mine exactly, but I'm thinking it's in the 30hr range.

I, too, have WiFli eTap and am experiencing the "sleep" issue...fresh battery charge, takes a snooze for 20 sec. or so then comes back to life. During it's nap the front derailleur works fine, rear goes neither up nor down. All is fine after a bit of a wait. Not gonna warranty it out until winter time unless it gets a LOT worse.
Happened 4 times during a 110 mi. ride week before last, and then not at all after having sat out in pouring rain all night and riding 80 the next day. |

Please excuse the brainstorming . . . but could it be that the B-adjustment screw is set with the pulley just a little too close to the cluster? Maybe the contours of the bigger cassette when using the WiFli rd have a spot where the cassette is closer to the pulley than it is at the extremes of the cluster -- but just BARELY too close, so that it sometimes works and sometimes doesn't. The condition described seems to be what would (logically) happen if the rd encountered some resistance when trying to make the shift.
Shifting the fd would change the length of the chain / distance of the pulley from the cassette, thereby freeing the rd. And shifting just the rd would register a shift electronically, but the rd would physically back away from the obstruction. Are all your chainrings, cassette, and chain length within recommended specs? I don't know if this makes sense -- just trying to help. It's a theory. |
Hello Good people of bikeforums!
Almost a year later, with a very good season in 2018 thank you very much :beer: , the problem just went away . Timeline: DEC17 I buy the sram eTap off of AMAZON (thank god, because their support and return policies are absolutely amazing) JAN18 I start having issues with the derailleur sleeping and get a replacement from Amazon here note that the groupset got cheaper on amazon , and they refunded me completely and I repurchased it, this way saving about 150euros from the original purchase (<3 amazon) MAR18 The issue still there , it even happened during a race :troll: :injured: MAR18 I get another replacement from Amazon after that I think it happened just once or twice during training , and it went away . absolutely no idea what fixed it... during this time , I did mess around with things , including the B screw that some people mentioned , but can't say for sure that's what fixed it . |
I'm now four rides without a problem after the B screw adjustment. By way of background, this is my second wifli etap rear derailleur. The first had the far more insidious problem where it wouldn't move at all, but then moved suddenly with all the stored changes (very dangerous). It was replaced by SRAM under warranty. This time the problem was different, exactly as described by many on this thread. I really didn't want to have the hassle of another replacement and the subsequent time wasted. That is why I tried FlashBazbo's advice. I am now pretty confident that it is fixed this time. The prior problem definitely required the replacement strategy. Hope this helps someone.
