I did something really stupid today........
The gears on my push-bike were adjusted this afternoon. My 18 speed derailleur system is working as good as I can get on 15 speeds. Why only 15? Well the largest sprocket on the rear gear set didn't pass quality control ( if they had it) as can be seen in the picture. Note difference in height of teeth on the innermost gear. The limit has been set so it won't change into that gear.
Even the front derailleur needed adjustment as it would only change between the inner and middle gear. Again an adjustment to the limit screw and all three low, med and high gears now work.
Now I have no excuse not to ride it.......but not today
