This post experienced failure on this am ride intended to go around Teresa. I could only shift to the 5th cog and no more up ot Mambog. So this post decided to return because that meant I could not negotiate steep hills at Teresa and Antipolo because the shifter was not working properly.
Could it be failure of the shifting mechannism inside STI? Did the pawls or the plastic dram fail.
Five km from Mamabog on the way beck this post tried to examine the tightness of shift cable. And lo and behold, it was. The cable was loose by at least 4-5 mm. I tightened the cable, (pulled by hand and later with a plier when I reached home) and tightened the nut the cable nut well. And the problem seemed to have been resolved
Cables and uts do get loose and they result in such function failures Be sure to bring tools
Thought I have to see Mario Toledo again or worse buy a new shifter. Good for me. Savings
