Hi all, we recently bought a Vogue Carry 2, really nice to transport the kids around town. However I noticed that the gears/shifting will go up, but not go down. I checked the adjustments of the cable and that's alright. The cable is able to pull the gears/shifting tighter and therefor shifts up. However, I think there might be a spring inside that isn't working correctly or I need to use some kind of lubricant. I did it once with some spray (WD40) but that only worked for a short while. Any hints?
