Stiff Gear
Hello, I have a hybrid bike and use it every day to go to university. Recently, the gear become stiffer and very difficult to change to 3rd gear at the front derailleur. I have altered the cable for front derailuer before and it is now worn.
1. Is the main reason unable to shift gear to a worn cable?
2. I try to adjust how limit screw (the low limit works) but the high limit one does not alter the position of derailuer in anyway, any suggestion?
3. My rear mudguard is broken and thinking of replacing it. Is it necessary to have a mudguard? (Sometimes at weekend I do cycle for long distance on towpaths).
Thanks.

Try giving the front derailleur pivots/spring a soaking with penetrating fluid (wd40 / GT85 etc) and work it in by repeatedly pulling the cable from under the down tube. They can seize up. Make sure your adjustments to the limit screws (H/L) aren't stopping the derailleur shifting properly.0

Thanks for the reply. I have taken my bike to check and cable was replaced and the shifter was lubricated. They also suggest to replace the front derailleur which they say is bent. How does a bent derailleur affect shifting?0

Depends what they mean by bent, if the cage guide plates are bent and out of alignment, you will have problems shifting from one chainring to the other/derail the chain. The guide plates could make contact with the inside face of the crank arm and/or wheel rim and tyre, depending on how bad it is.0
