Hi all. New here. Wondering if I might get some suggestions or advice on a mechanical issue I'm having.
I have a bike with 3 chain ring setup in the front that will not jump to the big chain ring no matter what adjustment I make.
Touring Bike, bar end shifters, Shimano Tiagra 3 Chain Ring front, Deore 9 Speed Cassette.
I've adjusted the angle on the derailleur to try different combinations, the height down to about 1 mm over the big chain ring, the cable length, barrel adjusters, and high/low limit screws in many different positions. No big Chain Ring. 🙁
Middle and small rings/gears, no problem. The position of the chain on the rear cassette has little to no bearing on the situation. Obviously, you can get some cross chaining, but the position on the rear will not really help or hurt the situation.
The Front Derailleur will move all the way over the large front ring but will not "push" it over to to make the change. And there seems to be ALOT of pressure on the cable. So much so that it frayed one cable. So I just replaced it and now while attempting to adjust it again, it pulled it out of the cable holder on the Derailleur again.
So I got frustrated, and since it was already out, I decided to physically pull the Front Derailleur by hand and get it to the big Ring. No dice. Won't pull far enough.
Any suggestions at all? Thanks for reading.
