Hi All,

I am new to bike maintainance. I recently tuned up my Trek 800 mountain bike. I went to the Park Tools website and read their reference notes on adjusting the derailleurs. My bike derailleurs now seem a lot more responsive. However, when I did a test run, I noticed one problem. The front derailleur has difficulty downshifting from the large chainring to a smaller chainring if I am riding up a steep hill (with lots of torque on the crankshaft). When I am riding on a flat surface, I do not have any problems shifting with the front derailleur.

Is this a problem due to overtension in the front derailleur gear shift cable? Or is this a problem due to the adjustment of the front derailleur stop screws? How do I address this problem?

Thanks!
