The wind was so cold I wore the winter Dintex/HeatPax gloves. Though I took the GripGrab Windster gloves to change into later. Gears still jumping. 21 miles. Going out again. Plus 7 more miles. A half turn more on the adjuster seemed to fix the gears. Passed my first 1000 miles for this year. About time too!
Friday 7th 39F, 4C, high cloud with a hint of brightness, breeze picking up. Rain and wind promised for this afternoon.
I am wondering whether I reversed the cable clamping plate on the Ultegra rear changer when I put it back together. I had been experimenting with different cable clamping before fitting the ShiftMate. The clamp was reversed and I put it back to normal. This may be the reason for the newly indecisive indexing. The odd thing is that the ShiftMate is supposed to have taken care of the incorrect pull-per-click ratio of Campag Ergo levers with Shimano changers. [Shimergo] So cable re-routing should not have been necessary.
