So I've swapped out my cranks and chain rings from another bike successfully (after I figured out that there is a difference b/t ISIS and Tapered Square!!).
Anyhoo, had to adjust the front derailleur cage now that it has to fit over a larger set of chain rings. My problem lies with, I seem to be able to set it to change b/t the 2nd and largest ring. But it just won't go down to the granny ring. I've fiddled with it for >2hrs.
Each time I manage to get it to switch from one ring to the other, the other one will not work.
Here's the procedure that I gathered from the many DIY videos.
- Set chain to largest rear cog against smallest chainring. Adjust height of derailler cage to make sure it can go past the largest chain ring.
- adjust Low limit.
- Tighten the shifter cable
- Set chain to smallest rear cog against largest chainring... but cage just won't want to move to largest chain ring!
- Tried releasing the tension of the cable, but it goes nuts thereafter.
So right now, I just adjust the derailleur to work with the middle and largest chainring. Granny ring is not possible. Please help!
