Completed the EGR wired build.

Nothing to worry about. Wisely you seem to have made an inspection post the roof rack ride in the rain. There can be similar ingress to wheel bearings, bottom bracket and any bolt on the bike.

Marine or Lithium grease is recommended for headset races. A selection of picks can help to lift and check under bearing seals in cartridge bearings.

Any frame bolts you might remove wipe down and refresh anti seize, same for seat collar, headset top cap, stem bolts.

Water ingress can lead to surface rust on cartridge bearing outers, usually very minor and will not cause a problem.

Just programme frequent maintenance inspections for yourself which will help you to protect your bike and components.

Greetings all!
I am having problems with binding and pairing the rear derailleur and shifter on a new EGR V. 3 installation. I cannot get the shifter to change gear up or down after supposedly pairing.

Success! I think I hope. For the benefit of other readers who may also come across this problem I will share my experience. Looking for any glimmer of help online I benefited from Google Ai on my Android smartphone. Having trawled through lots of entries from Facebook comments and forum replies it was the addition of the 'if you tell me this.....' additional bits of info that got me there.

So what worked? The Ai suggested deleting the rear mech from the app. Then to delete to cache of the app. (I in turn deleted the storage) It then said delete the app and reinstall. Connect the app to the derailleur and then try to pair with the shifter (controller) My first attempts at pairing failed. It was the adamant statement inferring you must be doing something wrong when pairing that did the trick.  I tried again. Finger on the button on the mech I pressed the shifter button for the four seconds, light on, immediate quick brief click on the mech button. It worked!

I also believe I have solved the clicking on gears nine and ten (10 speed) I think it will resolve when setting high and low screws to match the cassette when the wheel is installed. I will let you know as I progress the build later on.

Connection to the app registers the rear derailleur and informs me it has the latest firmware. Attempts to 'see' the controller for firmware update fail.

In the pairing, hold shifter button for four seconds and immediately press the rear derailleur button there is communication. A motor sound and a mechanical 'nudge' result. There is no shift resulting from clicking the shifter paddles. Green light shows in the shifter with each click.

The rear derailleur will shift and and down via the app. In the app I have set to 10 speed. As yet I have no rear wheel, cassette, chain on the bike. Ninth and tenth gear which would be smallest two cogs mech motor is whirring and clicks but makes the shifts. I have written to my seller, no reply just yet but still very early to expect one.

Any thoughts and suggestions from the community?
