- Di2 Question (Road)
I have a weird issue with my Ultegra 11s setup, which until now has been faultless
Shifting into the easiest gear, the mech engages the biggest sprocket, but it makes a ticking noise for 6 or 7 seconds, after which it drops back onto the next sprocket down.
I have set the limit screws, and am sure the mech hanger is fine. The ticking noise makes me think it’s something else, as even with the chain off and wheel removed the mech automatically shifts once the 6 or 7 seconds of ticking are over.
Anyone had experience of this and resolved it?Posted 2 months agojohnhighfieldMember
Sounds like your limit screw as Di2 over moves the derailleur to ensure it changes & then drops back a little. It sounds like your limit screw is stopping it over reaching & so when it drops back it’s in the next gear. I would try tweaking the limit screw a bit.Posted 2 months agoMister PMember

But have you put an alignment tool on it? That would be my first job then work from there. If it’s been faultless up until now and you haven’t fiddled with the limit screws then it could well have had a slight knock on the rear mech. I have to check mine every once in a while where it gets knocked in the bike shed at work. A quick tweak with a hanger tool always sorts it.Posted 2 months ago
